    "You don't think that AWD delivers a safety benefit in low traction conditions?"

    I think that any AWD system that results in the BRAKING effects of engine compression being primarily at the rear upon throttle lift or "clutch" downshifting will add some level of safety factor in low traction conditions.

    I also think that any FWD or F/AWD can too easily lend a false sense of security to a driver not fully knowledgeable or experienced in the dynamics of handling these on a low traction surface.

    Sorry if I have come across as a fan of Honda, my position is, has been, that the SH-AWD system is the best of the best for vehicles with a sideways mounted engine, or any "base" FWD converted to F/AWD.
  • Have you ever owned an AWD vehicle? The benefits of delivering power to all four wheels are not restricted to engine braking.

    "I also think that any FWD or F/AWD can too easily lend a false sense of security to a driver not fully knowledgeable or experienced in the dynamics of handling these on a low traction surface. "

    As that represents the vast majority of cars and crossovers sold in the Us today, I hope not......

    "The benefits of delivering power to all four wheels is not restricted to engine braking.."

    Not what I said, NOT nearly what I said.

    There are LOTS of advantages of AWD...

    But all of those advantages will be easily overcome if engine compresssion braking is primarily at the front wheels, as it is in most F/AWD systems. The new Acura TL is getting a manual transmission, that would NOT be a viable option except for the ability to have rear torque biasing upon a downshift, or severe throttle lift, on a low traction surface.

    That's why there are very few stick shift FWD vehicles in the marketplace, and getting fewer every year. In the hands of an inexperienced driver they are PATENTLY UNSAFE in wintertime conditions. Even with FWD automatic transmissions the AAA is recommending that owners practice quickly shifting into neutral in preparation for doing that safely should the need arise, severe "plowing", understearing, on a low traction surface.

    Personally I would add my suggestion, gained from real life experience. In those same circumstances the use of rear implemented e-brake, judiciously/slightly, can be a tremendous aid in both holding the "line" and slowing the vehicle to gain more "bite" for those front wheels.

    "Have you ever owned an AWD vehicle...?"

    Yes, first an '85 Jeep Cherokee Limited, then a '92, both with RWD/AWD/4X4hi/lo modes. The '92 has been retired to a north central MT cattle and wheat ranch and is still doing stellar duty.

    A '94 AWD Ford Aerostar, "donated" to son.

    A '00 AWD Chrysler T&C, "donated" to daughter.

    An AWD '00 RX300, traded.

    Currently...

    A '94 AWD Ford Aerostar.

    2001 Porsche 911/996 C4

    2001 AWD RX300.

    The '00 Lexus RX was primarily FWD using a VC, Viscous Clutch, to apportion torque to the rear if the front wheels slipped consistently, for a prolonged period. The '01 primarily uses TC braking to apportion torque and has a more flaccid VC for backup. The VC in my '01 has failed completely, ~80,000 miles, so I only have TC for AWD fucntionality.
  • Your experience with modern AWD systems could use some updating.

    Sure...

    Currently looking closely at the CX-7, RDX, and Ridgeline.

    I Like the RDX's SH-AWD system, the CX-7's DISI engine, and the Ridgeline's utility. But I would settle, quickly, for a CX-7 with the FEH/MMH/Tribute's hybrid drive.

    Suggestions...??

    But expect knowledgeable rebuttals.

    But for the moment I'm awaiting the details of the 2010 RX350 AWD system.

    Otherwise I will probably be converting my F/AWD '01 RX300 to R/AWD.

    > Instead, the rear differential is constantly overdriven by 1.7 percent. During straight line performance, that difference is scrubbed off by the clutch packs.

    Hmm.. I can't see how this can possibly help on fuel economy.. I look forward to the 2010 RDX rumoured with FWD as a powertrain option.
  • wwestwwest Posts: 10,706
    "..scrubbed off by the clutch packs..." "...During straight line performance.."

    In this case the only time the rear clutch packs are seriously engaged is during moderate to heavy acceleration, and you can't accelerate forever.

    The RDX already has a FWD mode, all you need do is install a DPST switch to interrupt the flow of electricity to the rear clutch packs. Since they have positional feedback you would probably get a "don't care" failure code.
  • I chose the EX35 over the RDX due to the fact that the EX35 is rear drive based on the FM platform, (no rebadged Nissan version, where as the RDX is a rebadged Honda CRV with a turbo, other enhancements) handled better, nicer interior, more refined in my opinon vs the RDX. I like the EX styling better. The only plus of the RDX was that it has more room in the backseat/cargo, but not a lot more. There was very good pricing last month on the EX, $7k under MSRP. The best RDX pricing was only $2k or $3k under MSRP. IN the end the EX was nearly $3k cheaper than RDX.

    If ride quality is a priority of you then I would suggest the EX35 over the RDX. The ride on the EX35 was much smoother when I test drove it compared to the RDX, especially the models with AWD. The RDX with FWD had a slight improvment in ride quality over its AWD counterparts but still was much more harsh/choppy on the majority of surfaces compared to the EX35.

    I also liked the body style a little bit better on the EX35 than on the RDX. Don't get me wrong the RDX is a great looking vehicle with lots of power with that turbo I4, but if ride quality is a priority then get the EX35.

    Please, don't think I'm hating on Acura because I do drive a 08 TL :D

    The only negatives of the EX35 is the rear seat legroom and cargo is less than RDX. Otherwise in my extensive test drives and opinion it wins in every other category. I didn't like the turbo lag or handling on the RDX, RDX is front Wheel Drive based. RDX has poor fuel economy for a 4 cylinder vehicle. The EX's V6 gets same or better. Both use premium gas, so no savings there.

    The EX35 has no lower Nissan equivalent branded vehicle. The EX35 is on the G35/G37 FM REAR drive platform, where as the RDX is an over-glorified Honda CRV, same platform. It looks similar, from the sides, etc.

    With the deals going on now, the EX was cheaper than RDX out the door.
  • You need to keep in mind you won't get a cargo cover if you buy a standard EX35, you have to go to eBay for that. WTF in their mind of the 35K luxury car maker.

    The RDX is NOT based on the CRV just like the EX35 is not based on the Rogue... UGH - get your facts straight before you present them as facts...

    They are both great cars.
    RDX handling is better. Size is better. Reliability is better. Price is better.
    EX35 ride is better, interior materials are better

    honda>nissan
    Acura> / = infiniti

    "..RDX handling is better.."

    As good, EXCELLENT, as is the SH-AWD it does NOT compare favorably with even a simple RWD vehicle. Infiniti does not believe in FWD or F/awd vehicular drive systems for a good reason.

    If you look at RDX and CRV again, closely, they are identical.
    I would go with EX35 if I don't have children.
    Even a new Huyndai Tucson is better than RDX in many ways. Its style is so obsolete.
  • How are they identical? Powertrain is different, body is different, suspension is different. Somewhere on the web, there's a video interview where the RDX is compared to the CRV and the guy says they share 7% of the components. I'm literally looking right at my '08 RDX and my neighbor's '08 CRV.

    They look identical when you look from outside with same platform. If you put roofrack on CRV and look at it from back, side, and front, people will get confused.

    You don't do a surgery to check internal organs to say 2 people identical. It just the look.

    Maxima and G35 using same engine/transmission, but they don't look identical.
    Anyway, CRV and RDX are pretty much no difference, so why convince otherwise?
    yawn...

    I just want to make sure I'm getting this right.

    The cars look similar, so that means they're the same. Good one. Like saying the EX35 is a Rogue.

    After your last post, it's pretty clear you don't know anything about these vehicles, I would have loved to race you for slips w/ my Grand National (just a black Regal, right?), but just for kicks, how does Nissan use the Maxima's drive train, a front wheel drive car, and somehow make the exact same drive train work in a rear wheel drive G35 (based on a rear wheel drive Z chassis in case you didn't know). And by extension, since the EX is based on the G, then they're the same as well?
