    Good gearing and a great engine can do wonders. Acceleration, top speed, passing capabilities are not mutually exclusive with fuel economy and lower RPMs at higher interstate speeds. Why would I only want to get 18/25 mpg rating and need premium fuel, not to mention having the engine rev about 500-1,000 RPMs higher than really necessary if it used a .7 or .75 5th overdrive? If I need to pass, I have 4th.

    The 4-speed automatic I-35 with 255 HP 3.5L V-6 is rated 20/26 mpg. The 5-speed automatic ES300 with 210 HP 3.0L V-6 is rated 21/29 mpg. Heck, the ES300 comes with V-rated tires and a 140 mph top speed.

    how fast are you going to corner in an ES :)
  • stanny1stanny1 Member Posts: 962
    This is confusing! One needs to make a distinction between FWD and RWD cars. The IS300 is a performance car. The ES300, Altima, I35, etc are FWD appliances. No one should pay more than high 20's for a FWD car. They cost less to make and have so many compromises. RWD starts at about 30k and there is a reason. I wouldn't even want to find the cornering limit in a FWD. What fun is trying to counter the laws of physics in a FWD? FWD, automatic tranny appliances are a dime a dozen. It's the exceptions that are noteworthy, and those are RWD.

    First, riez, on the comment of "Nothing worse than having to drive 1,000 miles at high interstate speeds listening to the engine turn over at 3,000 or more RPMs" my '92 ES300 had a 5-speed manual and turned 3100 @73mph in 5th (I don't know the ratio). The engine was not noisy to me at that speed, it sounded quite nice and quiet. And, because of the engine being relatively in it's power curve, the car never exceeded +/- 1mph through the hills of WV with the cruise set (I'm not from there). And on that note, I averaged 28-31 mpg. Not too bad, I wish I still had the car.

    Second, silverlex, I agree. Riding 1000 miles in any camaro would be a lot worse than listening to that smooth Toyota engine purr, and that's not even bad.

    1. RWD is readily available for the masses. RWD can be as cheap and plentiful as FWD, and just as much an appliance (and poor performer). I can open the automobile dealer section of newspaper and find tons of inexpensive RWD Crown Victorias, Grand Marquis, Mustangs (base & GT), Camaros (base & Z28), and Firebird (base, Formula, Trans Am), not to mention hordes of pick-up trucks and 2WD SUVs. Unless one loads up on the options, a customer can buy many for well under $20,000 and nearly all for under $25,000. Hard to pay even close to $30,000 in this bunch (maybe the deep discounted Lincoln TC)! This spring for about $30,000 you will be able to buy the 300 HP Mercury Marauder (based on Grand Marquis)>

    2. If I'm crusing 1,000 miles from point A to point B at 75-85 mph, I'd much prefer my engine turn over 500 or more RPMs less. I'll have less engine noise. Less engine wear. Better fuel economy. Save $$$ on every tankful. So what is the downside? None, at least not in the real world. Why, oh why, won't these companies build .70 or .75 overdrive 5th gears in their performance sedans and coupes? Maybe the owners don't spend much time on interstates or scenic 2-lane county roads?

    Lexus would not have built the IS300 if it was not a totally separate market than the other Lexus models. The GS buyer is a luxury buyer who may know what RWD means. The ES buyer has no clue.
    He just wants a pretty Lexus. The IS300 wants lean and mean. Luxury is secondary to performance.
    Many Bimmer owners buy an image. They don't know about FWD and RWD, couldn't care. Luckily, they mostly buy the non-performance models and mostly automatics. They will never slip and slide the rear ends like manual owners can and do. The new 7 series is for trinket lovers - it's just too big to do anything with. The average owner has too much money and is too old for any testosterone kicks. It's just about as sporty as an STS. Rolling coffins club. I want my heart attack as I slide around the corner. I'm only 53. I'm too young to drive like I'm already dead.

    I'm 6 foot 6 and that car fits me like a tight pair of driving gloves. I'm glad they aren't selling well cause that equals depreciation. I refuse to pay that much for a car. Luckily it's a Toyota so it'll drive just as nice with a few miles on it but will be a lot cheaper.

    Looks like there are one or two folks who need to be reminded of some things that they've heard previously in this discussion.

    We are not going to turn this topic into a 3-Series vs IS 300 argument. Nor are we going to be uncivil in the ways that one or two of you have been previously in discussing these issues. It's just not going to happen again; we have been there and we have done that and we are through with that.

    We have a fine place for a civil and polite comparison of these two vehicles here: Lexus IS 300 vs. BMW 3-Series. Anyone who wishes to contribute respectfully to the conversation is welcome.

    Thank you.

    We'll keep it toned down, even though you probably drive a Bimmer.(Just Kidding)
  • patpat Member Posts: 10,421
    Oh yah, I get a new vehicle of my choice every year courtesy of my employers in the Town Hall, donchaknow.

    This year I think I get to choose between a scooter (manual of course) and roller skates (the 30 year old kind that clip on to your shoes with a key, and then fall off and make you fall DOWN on your face and of course you lose the key).

    ;->

    Ahem. Back to the IS 300....
  • silverlexsilverlex Member Posts: 156
    Those two modes of transportation should be debated in the Scooter vs. Roller Skates forum. ;)
  • patpat Member Posts: 10,421
    oh yeah, sorry. I'll get right over there. :^)
  • iontrapiontrap Member Posts: 139
    I agree with you 100% on both points. I'm 6'6" also and it is not easy to find a car that fits as nicely as the IS, but the car is not worth the price tag. If it was priced closer to say a Maxima, then I'd seriously consider one.
  • silverlexsilverlex Member Posts: 156
    Are you serious?
  • stanny1stanny1 Member Posts: 962
    Comparing a FWD with a RWD. A Maxima? An IS would run circles around it. The cars have totally different dynamics. The Maxima may have more power, but keeping it on the ground is the problem.
  • fxashunfxashun Member Posts: 747
    It's a nice car. Priced just right for it's intended market. But I just think that it's too darned expensive. Especially when you consider how depreciation hits cars these days. There's no way I'm blowing that much money on a new car.
  • hvan3hvan3 Member Posts: 630
    It's no secret that Lexus tries to appeal to the masses by coming out with "more for less". Lexus has done everything possible to get buyers to their showrooms, even low lease program.

    Those who can't afford BMWs simply buys the souped up Corolla. This is what seperates the haves and have nots. If Lexus priced their IS in the same price range as the 330, no one will be buying the IS. Lexus knows that!

    Regardless what incentives Lexus gives out, the fact of the matter is that the souped up Corolla looks just like an aftermarket boy racer car priced in the entry level luxury price. The aftermarket look does NOT attract the masses. That's a fact and the sales figure proves it!

    The fully loaded Altima will steal some sales from the IS. By the time G35, CTS, Madza 6, A4, and others come rolling along, poor IS will lose more sales. Too bad! Competition is great, isn't it?
  • stanny1stanny1 Member Posts: 962
    I had the last of the souped-up Corollas. It was a 1974 SR-5 modified for slolom racing. It was rear-wheel drive. Then the Corolla went FWD. An econobox appliance. How could you compare a FWD appliance with a purpose built RWD sedan? Much more expensive to build. More parts. More labor. The IS300 is so close to the Bimmer that they are scared. BMW lowered prices recently or have you noticed? I think the IS is honest to it's purpose, which is performance. BMW sells alot of pseudo-plush cars that will never really be driven like the average IS will. If the IS repels some drivers, there are paddy wagons galore for them. The IS is just the initial thrust for Lexus. The pursuit of perfection may bump up against and push the ultimate driving machine very soon. And the G35 is coming up very hard and fast also. It's going to chew the M3's tail.

    "The fully loaded Altima will steal some sales from the IS. By the time G35, CTS, Mazda 6, A4, and others come rolling along, poor IS will lose more sales."

    Hvan-flawed logic, you've listed cars that for one are aimed at totally different demographics. And that cost between $16k and 40k. What's your point here? Your always bring "new" models into the equation. Did it ever occur to you that Lexus does redesign its vehicles as well??? Of the cars you've listed the only direct competitor is the A4, the G35 (Nissan Skyline) and CTS aren't available, the Mazda 6 ? please, Altima will NEVER have any affect on the IS300 sales, again different demographics. How many people do you think go into a Lexus dealer and say, "I'm debating between an IS or Altima." Also in case you haven't noticed the majority of automakes. are offering incentives, low financing, and subvented leases to generate sales, NEWS FLASH.... The economy isn't doing all that well.
  • patpat Member Posts: 10,421
    We are discussing the IS 300 here, and ONLY the IS 300.

    We are not going to use this topic for the heated comparison argument that was taking place here - I was quite clear about that in my post last night, so I don't know why some of you even wasted your time. Please go to the comparisons board. If a suitable topic does not already exist, feel free to create one. But do keep in mind that posts on that board must conform to the civility and respect portion of your Membership Agreement as well.

    We are not going to use this topic as a place to slam each other. Not only was I clear about that last night, it is a message that you have heard repeatedly from me in this discussion and others throughout the Sedans board.

    I'd like to remind a couple of you to leave the management of this discussion to your host. You only make the situation worse when you respond to posts that are clearly outside of the Membership Agreement. Either drop me an email, or trust that I will almost always show up at least within 24 hours, if not sooner. In either case, PLEASE do not respond. You escalate the problem and subsequently make my job very much more difficult.

    As all of you already know, messages posted here must be worded respectfully and civilly. That is a requirement of your membership in Town Hall, and all of you surely know by now that I enforce that.

    If any of you wish to discuss what has happened here, feel free to contact me off-line.

    I am thinking about leasing an IS300 if I can get a good deal. How much room is there to negotiate the MSRP, I know all the other parameters are non-negotiable.
  • jkmfromlajkmfromla Member Posts: 22
    i've been seeing more and more IS300's on the road lately. and it's not the same cars on the same commute either. i live in so cal and i've seen them in the south bay, westside, orange county, etc. not sure if lexus reduced the price, increased incentives or if they got popular overnight, but there just seems to be more on the road.

    i wonder if the people who whine about the IS300 actually own one.
    engine noise? i avg around 80-90mph on the fwy and i have no complaints.
    performance? it's sneaky fast. before i know it, i'm going almost twice the speed limit and handling/ride are great.
    gas mileage? could be better, but if you're willing to spend $35K for a car, who cares if you have to spend an extra $110/year for gas (23mpg v 20mpg, 10K miles per year, 17.5gallon tank and $1.70/gallon).
    competitors? when i bought my car (may '01), the competition consisted of the 325i, A4 2.8, TL-S, C240 and the I30. i didn't want a fwd and the IS300 was a better value than the 325i and C240. i don't think you can compare Nissan's, Mazda's, and VW's to BMW's, Lexus's and Audi's...well maybe Audi's to VW's.

    my only complaint so far would be the lack of trunk space due to the stationary rear seats. a golf bag and a few bags of groceries and the trunk gets almost full. then again, this isn't a family-hauler. if i wanted more cargo room, i should've bought the Envoy.
  • v_techv_tech Member Posts: 52
    great points jkmfromla.

    the IS300 for many reasons is a much maligned little sedan. it is sad that lots of folks fail to see the enormous potential of this new lex. as we all know this car is no slouch right now. it can be tuned to the gills as this months turbo magazine points out. the line for aftermarket IS parts is enormous.

    looks and luxury seem to be its biggest criticism. some folks fail to accept its gen-x looks. others with vision and a open mind can easily see that all cars out there swim in a sea of sameness. the IS is not like the others. i laugh at the folks who criticize its interior. it may not be up to par with a 40K MB or bmw in their eyes but they overlook the obvious. THIS DAMN CAR IS NOT 40k OR EVEN CLOSE TO IT!!!!!! if you look inside the 26K dollar sedans today japanese or american those interiors are what you call cheap. is it really worth a mention?? what for?? what would you expect from a 26K dollar car?? for 26K they can get some great performance but something has to be sacrificed. i don't understand what kind of logic some people have in edmunds. then people will say that the IS has sacrificed some things with respect to its competition and i say, "with respect to a 39 to 45K car, i hope so otherwise one could call lexus a rip-off joint like its rivals are right now." =) the competition wants to believe that the sacrifice is valued at 7-10K dollars but that is a complete joke!! Total value is in favor of the IS300 beyond a shadow of a doubt.

    someone can correct me but for 10K more on the base price of a manual or auto IS you would think that you could squeeze in a turbocharged or supercharged engine and not really sacrifice a damn thing that already comes on this car. in fact, they could remove all the cheapy plastics that have brought it so much criticism and maybe make the backseat a tad roomier to appease all the whiners. for 42K i bet we could have a IS300 that could appease all the whiners and boast 260hp and dust all of its competition in every performance category. =)

    I am interested in the SportCross and went by the dealer to check them out. When I got to the dealer I was ignored by the sales staff; I don't look like someone who would buy a lexis :-) This was great because I could fiddle around with the car they had on the showroom floor without any pressure. I was kinded of surprised at the $36K MSRP for the car (roof, leather, limited slip, skidcontroll). This seems like 2-3K too much for what you get; the seats don't even appear to have a memory. Does the IS300 sedan have a seat adjustment memory? Why waste time asking a dealer sales rep who probably doesn't know.
  • lenscaplenscap Member Posts: 854
    I noticed some posts last week and wanted to respond:

    1. Sales figures can be seen at prnewswire.com around the second or third of each month. That's when the manufacturers release their sales press releases for the previous month. (Go to the home page, select industry, then automotive).

    2. I was the one who posted on the ES300 board about Lexus admitting the IS300 interior was not nice enough. I attended a Lexus owners focus group back in February (I have a 1995 ES), along with 10 other owners and about 50 Lexus execs from Japan (most needed a translator). Although our session was only for GS and ES owners, the IS came up. The Lexus people said they underestimated the need for a more upscale interior in the IS and said point blank they made a mistake. They said the next-generation IS will have a significantly upgraded interior, especially in terms of materials used, although it will still be sportier than other Lexus models.

    Hope this clarifies some stuff.
  • charliemikecharliemike Member Posts: 87
    I read your post several times but I still can't see what you are trying to say.

    A loaded IS300 hits around $39k.
  • stanny1stanny1 Member Posts: 962
    Wow, at that price, there are many alternatives. You could have a V-8 (Lincoln LS, that is). I leased an LS Manual for 32k. This is almost BMW 3 series territory. Or about a year-old 5 series. Way above what the king kong G35 is supposed to sell for. How much is the Lexus name worth?
  • silverlexsilverlex Member Posts: 156
    If you choose the Auto with Nav and even then you're not going to pay 39K unless you're the type that pays sticker (ie, sucker). Dump the nav, and of course you save an instant 2K.

    Same thing for the 5M loaded to the gills will be 36K and knock off a couple grand which from what I'm reading seems to be the current discount for a total of 34K.

    Shop around and do your research. The deals are out there.
  • stanny1stanny1 Member Posts: 962
    I live in San Diego. Here is one dealer's lease terms on a 2002 Sportcross with CD, Leather, power windows and door locks, cruise control, tilt wheel. 5 at this price. $399 per month, 39 month lease. Payments plus tax and license. 39 month closed end lease with puchase option. No security deposit required. Customer cash $4162 (total drive off). Excess mileage fee of .15 per mile. 12,000 miles per year.
    IS this typical???
  • jrct9454jrct9454 Member Posts: 2,363
    ...that's widely advertised right now. Work them on the amount of cash required up front...that's a significant leverage point on leases.

    Great point! I started shopping for a new car this weekend. Started with the Honda Accord. Nice car for $26K but the interior isn't great. Next looked at the new Camry. Nicer, but looking at about $30K. Finally went to Lexus and looked at the IS300 and fell in love. It's definitely, IMHO, the best looking of all three cars (both interior and exterior.
  • bluebeastbluebeast Member Posts: 258
    Sounds like your in the price range for a Acura TL-S !! Have you looked at it? I love my 98 GS300 & 96 LS400, but that TL-S is really sweet.
  • jkmfromlajkmfromla Member Posts: 22
    I paid less than $35K out-the-door for my IS300 with LSD and seat warmers (all the options). Maybe the sticker price is $39K fully loaded, but you can do better than that. When I bought mine, I just called up about 4 of 5 dealers and told the sales managers what I wanted and how much I was willing to pay. All but one was willing to negotiate and the one in Santa Monica gave me exactly what I wanted at the price I wanted to pay. I drove in, wrote a check and left with the car. Couldn't have been any simpler.
  • fxashunfxashun Member Posts: 747
    But I think the outside of the ES300 bites. The interior is very nice though.
  • antictantict Member Posts: 4
    Although I understand your pov, to say a 5th gear that's not .75 or less is largely dependent on the engine and the car you're driving. My Celica GTS turns 5,000 rpm on 5th gear @80 mph. Even on 6th, it turns 3,800+ and it gets 32 mpg, more if I use 6th gear more often. And is it noisy? That depends on your pov also. I like to hear engine sounds when I drive.

    On my 5-speed IS, I actually wish the gearing was a bit shorter. And besides, as someone has mentioned, @80 mph, you hear more of the road noise than engine. I didn't buy my IS (or my celica for that matter) to be lazy highway cruisers. I want feedback and more importantly, I want to be involved when I'm driving. I would think that you'd agree with this part, and I suppose you'd prefer a different type of involvement. But to say there is no reason to make a 5th gear the way the IS300 is, is simply pushing your judgement and preference on others.
  • riezriez Member Posts: 2,361
    antict... Check out the abysmal EPA highway rating for the IS300. Far worse than ES300. IS300 is a small, light car with smallish displacement engine but the short gearing causes the engine to rev very high at high highway speeds. Lots of engine wear and reduced fuel economy. Those are big down sides in real world. And what does it gain you? Doesn't improve 0-60 performance. 0-100 performance. 1/4 mile. And if you need to pass or accelerate while driving 70 or 80mph, just downshift. There is no rational reason to have such a high numerical 5th gear! Boy racers may love it, but most ordinary buyers who might take the car for long interstate trips on business or with family probably would prefer a .70 5th overdrive.
  • fxashunfxashun Member Posts: 747
    I don't think it's necessary to have the engine screamin' on the highway. I'm not afraid of the gearbox and if i need more speed I can drop down a gear or two on my own. My Civic does 80 at 3000 rpm or so and has a gearing/redline top speed of around 170mph (if only it could). I'm sure Toyota coulda dropped the revs on the IS to around 2500-2750 at 80.
  • silverlexsilverlex Member Posts: 156
    I don't disagree that the average driver would like it that way. Although, is this car for the everday driver?

    Living in Atlanta, I appreciate the passing power in 5th. Doesn't make either one of us wrong per say, but it comes down to what you want. On a test drive with the TL, it was apparent 5th was useless for anything but "cruising". In the IS, I can go from 65-80 or 80+ while passing without changing gears. In my opinion, that makes for an overall more enjoyable ride instead of the constant 5 to 4 to 5 transition. And I'll say it again, the IS's straight six purrrs like a kitten at 3000 - noise is NOT a problem.

    That's just a preference. Am I in the minority? Most likely, but you have to look at who the car is aimed at - and boy racers aren't the only ones who appreciate a sports sedan with a little more kick in 5th. :)
  • mmcbride1mmcbride1 Member Posts: 861
    I agree about highway passing power. My A4 is quite similar to the IS in that regard, and I love not having to downshift to scoot past someone. Anywhere from 50+, the A4 does the job quite well in 5th gear (manual tranny).
  • antictantict Member Posts: 4
    I'm certainly not an automotive engineer, but on the IS300, I really doubt the taller ratio would improve the mpg significantly (meaning 25->29+). I believe it really boils down to personal preference. I wouldn't invalidate your preference for taller 5th gear, and I simply prefer shorter gearing, as fuel economy is not a major factor and IS300's engine noise at @80+ is even less of a factor for me.

    I suppose if you drove a Celica GTS, you'd flip at how fast the engine turns @80 mph on 5th gear, or even 6th gear. And as I've stated previously, I get 32+ mpg. The 2ZZ-GE engine is undoubtedly more efficient than the 2JZ-GE engine, not to mention nearly half the displacement (1.8L vs. 3.0L).

    As those who know Supras and Cressidas, the 2JZ-GE engine goes back a long way. I think they've done what they could to wring out efficiency and power out of this engine, short of turbo- or supercharging it.

    And the Civic Si does 4,000+ rpm @80 mph. As does the S2000 on 6th.

    Since everyone is free to choose, perhaps the IS300 is not your best choice.
  • riezriez Member Posts: 2,361
    Was looking at the R&T comparison of Audi S8, BMW 740i, and MB S55 AMG. Each uses a 5-speed automatic. The individual gearing for the 5 forward gears is darn near identical (e.g., 3.57, 3.57, & 3.59 in 1st and .80, .80, & .83 in 5th) but the final drive ratios differ significantly. Audi uses aggressive 3.73:1 versus MB's sedate 2.82:1 and BMW's middle-of-road 3.15:1.

    At 60 mph in 5th gear the S8 engine turn 2,400 RPMs versus 2,000 RPMs for S55 and 1,900 RPMs for 740i. The Audi is the lightest car with the smallest engine. It gets the worst EPA fuel economy rating and has the loudest interior noise at 70 mph. (If Audi wanted the aggressive final drive, they should've gone with much lower numerical overdrive 5th, say around .70.)

    So I all see is downside and no upside. More engine wear, more noise, and more fuel expense. If I can have less engine wear, less noise, and less fuel expense (without suffering performance loss or minimizing it), why wouldn't I?
  • antictantict Member Posts: 4
    There are other factors that contribute to fuel economy and noise than gearing. That was what I was trying to illustrate in my previous post.

    Do you own any of these cars, BTW?

    For most owners of these kinds of vehicles, fuel economy is not exactly on the top of their list of must-have features. And the idea of fuel economy is relative, as I showed you with my Celica/IS300 example. I didn't buy my Celica or my IS300 for fuel economy. If I were to, I could've bought the Insight which I believe gets 60+ mpg.

    For the ultimate in fuel economy and noise, all cars should idle @60 mph (super tall gearing). After all, one can simply downshift to 4th (or 3rd) to pass or to climb a hill.
  • riezriez Member Posts: 2,361
    Yes, but this is a pretty apples-to-apples comparison. Cars of similar size, weight, transmissions, and engines. They do have big difference in final drive and the aggressive 3.73:1 in the Audi S8 does make a huge difference in RPMs at highway speeds. If this big, powerful motor turns over at 2,400 RPMs at 60 mph, would love to know what it turns over at 74 and 84 mph.

    One thing interesting about people who can afford to buy these cars is that they tend to be smart and have common sense. Notice how the MB and BMW outsell the Audi in this class? They know it makes no rational sense to have gearing that reduces economy and increases noise and engine wear without having any appreciable meaningful impact on day-to-day performance in 99 percent of driving conditions.
  • antictantict Member Posts: 4
    I agree people who buy these cars probably have good common sense. But fuel economy is not the reason why MB and BMW outsell Audi, or even why people buy other similar cars. You can be assured that if you ever saw the market research facts for these cars, people do not place fuel economy near the top of the list, or count it as a factor in choosing one make/model over another. Although, you would be an exception.

    Your statement, "They know it makes no rational sense to have gearing that reduces economy and increases noise and engine wear without having any appreciable meaningful impact on day-to-day performance in 99 percent of driving conditions" seems flawed, as in your previous posts you were specifically concentrating on the 5th gear (or 6th gear) and final drive ratios. If one's daily commute or his driving habits are such that he'd never reach 5th gear, then the "aggressive" gearing on 1-4th gears would negate the fuel economy the 5th gear would have provided. By your logic in the last post, _all_ gears _and_ the final drive should be tall to accommodate a high fuel economy, less engine wear, and less engine noise to achieve "99 percent of driving conditions." Then what would be the purpose of buying a BMW or an MB if these had very tall gearing? Wouldn't a cheaper econobox provide the same or better outcome, use regular unleaded, and be generally cheaper to maintain?

    I won't deny completely gearing wouldn't have some impact to the car's fuel economy. But I doubt -- in the Audi S8 example -- taller gearing would contribute significant improvement to the overall fuel economy. Especially for those with more aggressive driving habits, or those whose driving patterns would rarely need 5th gear, or some combination of both.

    Use the lower gears. That's what the select-shift technology is for and why there are now 6 speeds transmissions. You would think that the straight six in the IS would have a flat enough torque curve where it would not have to run higher than 2500 or so at 80 mph. If it's curve were flat enough it would be able to pull as strongly from 2500 as 3000 or higher. I mean it's not that stressed is it?

    There has to be a proper balance when it comes to gearing. You DON'T have to sacrifice acceleration in 1st gear to get decent top gear cruising. Nor do you have to sacrifice top gear cruising efficiency for 1st gear acceleration. You can have a nice balance of both. So should the IS300.

    Check out Car & Driver's comments on the new 740i with 6-speed automatic. Has a gigantic overall spread (about a factor of 6 versus 4.5 for the 5-speed automatic). That can get you great acceleration off line and efficient top gear cruising.

    Chevrolet can get 28 mpg highway out of the Corvette Z06. 5.7 litre 385 hp. Good old American Iron that is.

    They can get excellent fuel economy out of it because the 6th gear is 0.50! I think it spins at something like 1500 rpm at 60 in 6th.
