    I don't know if I totally buy that. There is a force going down (mass*gravity), and I could see how that affects acceleration, but then there are things like the coefficient of friction/rolling resistance (with its function of mass)that affect the amount of energy required to get to a certain speed.

    Weight does matter, on a street car probably not much but in facing everything is as light as possible. Then they will add weight if they need to to bring it within the regulations. I read all about the power needed to overcome drag and how it's exponential but that was some time back.

    I would love to see an AWD Speed3

    Ahh....me too. Won't happen :sick:

    Anyone here bring up the new GT-R?? Not too shabby from what I have been reading. It does sound more profound if I were to say "I'll be outside washing and waxing my Porsche" rather then "I'll be outside washing and waxing my Nissan"

    Your right, my apologies. Forgot about that.
  • i love awd sedans, also love turbo powered engines.
    was upset when audi stopped producing turbo powered engines.
    this was one of the major reasons why i purchased the bmw 335xi & also feel it's a good candidate for, ultimate awd sedans.
    not saying,the RS4 aint a sweet awd vehicle, it's just that the cost & the potential, for the twin turbo engine of the 335xi, really gets me going!

    safe & fun driving gentleman!

    They still have the 2.0FSI, but you probably mean on their higher end sedans.

    The bar has just been set higher. Take a look. If this makes it onto an S4 with bi-turbo/SC IL6, the 335 will be surpassed for sure.

    Here is some ultimate slush in the GT-R

    image

    Perhaps this will find it's way in Nissans of lesser performance capabilities.

    Despite the published photos, it's something else to see the car in the flesh. Even more impressive is the car's performance, courtesy of a 3.8-liter twin-turbo V-6 that pumps out 480 bhp and about 430 lb.-ft. of torque. Nissan claims that the GT-R runs to 60 mph in 3.5 seconds, which puts it in Porsche 911 Turbo territory. In fact, GT-R project chief, Kazutoshi Mizuno, says that the GT-R lapped the famed North Course at the Nürburgring faster than the Porsche 911 Turbo. Not bad for a car that we hear will cost about $70,000. The car goes on sale first in Japan, then in the summer of 2008 in the U.S. as a 2009 model. R&T was the only magazine to drive a U.S.-spec model.

    Nope, these were siped and really meant for ice and snow.

    Even within the class of snow tires, you still have to make compromises.

    Here is an intersting concept:

    Heico Sportiv Volvo S80 T6 HPC review:

    The lights of Las Vegas reflect flawlessly in the gleaming aluminum paint of the Heico Sportiv S80 T6 High Performance Concept (HPC). Being shown for the first time in North America at the 2007 Specialty Equipment Market Association tradeshow in Las Vegas, NV, the S80 T6 HPC is a literal reflection of power, sophistication and athleticism as can be seen in its unique 7-layer "aluminum effect" body paint. But the S80 T6 HPC is more than just a pretty face. It`s a true example that a powerful luxury sedan can also be sensitive to the environment.

    "Heico Sportiv is honored to once again be working with Volvo Cars to build the exciting S80 T6 HPC for this year`s SEMA show," said Holger Hedtke, President of Heico. The 2007 show marks the second year Heico Sportiv has partnered with Volvo Cars to create a SEMA concept. This year, Heico shows its mettle with the S80 T6 HPC and the C30 Surf Pattern (see separate release). "The S80 T6 HPC is really where we put all our efforts this year," continued Hedtke, "It is our most advance concept to date and it`s one that Heico is extremely proud of."

    But getting to Las Vegas wasn`t easy. The project began as the curtain fell on last year`s SEMA show. Behind closed doors Heico executives sat down to put to paper the 2007 concept. The result is a Volvo S80 T6 that has been tuned to an amazing 350-horsepower while running on bioethanol fuel.

    When the S80 arrived at Heico`s shop in Weiterstadt, Germany in early 2007, Holger and his team knew they had their work cut out for them. The S80 began life with a 3.2-liter inline-six engine and front-wheel drive because production had yet to begin on the Volvo S80 T6, which has standard all-wheel drive. A new T6 engine was delivered from Sweden and work began in earnest.

    Performance

    The first order of business was to make a significant increase in horsepower. The standard Volvo T6 engine produces 281 horsepower, which is enough to move the S80 with spirited ease. But this is a SEMA concept and a significant bump in horsepower and torque were a necessity. Once the engine was modified to run on E85 ethenol, Heico turned its attention to maximizing power with high-performance engine software, a new intercooler and a stainless steel racing exhaust system. The end results were impressive: 350 horsepower at 5,500 rpm and 405 lb.-ft. of torque between 1,500 and 4,000 rpm. The Heico S80 T6 HPC is estimated to reach 62 mph in just 5.8 seconds.

    But getting that power to the ground required extensive work. As the standard S80 3.2 is a front-wheel-drive car it was determined that to truly explore the vehicle`s potential all-wheel drive was needed. Enter Volvo`s renowned Haldex All-Wheel-Drive system with Instant Traction. The system continuously routes power to whichever wheel has the most traction and Heico modified it with heartier gears to handle the enormous amount of torque.

    Stopping power is provided via a 6-piston braking system with custom blue-painted calipers and high performance brake pads. Volvo`s ABS and electronic brake distribution systems are fully functioning. Large 13.9-inch disc brakes reside in custom forged alloy wheels measuring 9-inches wide and 20 inches in diameter. The specially developed Volution X wheels are wrapped in aggressive 255/30R-20 Continental tires.

    The Heico S80 T6 HPC rides on a chassis that is 1.5 inches lower than Volvo`s set ride height and the sport-tuned suspension features firmer springs and struts at all four corners. "We aimed to tune all the components to achieve a dynamic yet harmonious ride. In other words, a true sports car experience without losing the luxurious and comfortable touch that is the hallmark of the Volvo S80," noted Hedtke.

    About Heico

    Heico Sportiv was founded outside of Frankfurt, Germany in 1995. It has grown to become Europe`s leading Volvo tuning firm. Heico has the longest running history of endurance racing featuring Volvo cars spanning 13 years. This serves as the engineering basis for offering high-quality components for Volvo road cars.

    That's cool. 50hp more than the S60R, which I think they discontinued, right?

    Here's something coming to a Lambo dealer near you.

    Lamborghini revealed its new Reventon supercar at the Frankfurt auto show earlier this year and just last week debuted the Reventon in the U.S. at the Los Angeles Auto Show. Based on the Murciélago sports car, the Reventon is said to be inspired by the F-22 Raptor fighter jet.

    There is more news regarding benefits to the ultimate traction gained from high-tech AWD performance. Like it or not, the wheels of progress are a-turning...the faster these systems get into vehicles, the safer we all are.

    Torque Vectoring: The Hyper-Smart, Fuel-Efficient Future of All-Wheel Drive

    Everyone knows there are control and capability benefits of all-wheel drive when you’re dealing with the elements—come sand or high water. Dropping an engine’s torque down to the ground with four tire patches instead of two would give any vehicle more traction. But headed to market in more and more performance cars are new systems that can seamlessly and instantaneously distribute torque to any single wheel at a time. Welcome to torque vectoring all-wheel drive.

    Most modern all-wheel-drive cars and SUVs already offer some type of computer-controlled, part-time engagement to save fuel. When the computer detects that one or more wheels is rotating faster than the vehicle’s speed or that the vehicle is yawing off its intended path of travel, the system steps in. First, it engages the other drive axle and applies a proportion of the vehicle’s torque to it. If the wheels continue to spin, the computer reduces engine torque or even brakes one of the wheels, if necessary.

    In recent times, these systems have taken a fairly radical step forward. Automakers have reinvented front and rear differentials to the point where an engine’s torque can be passed around—or vectored—to each corner of the car. In other words, your torque can go from front to back like a traditional all-wheel-drive setup and distribute from left to right on a given axle—all very, very quickly. It’s like having a computer-controlled, super-speed limited slip differential in each axle. This means not only great foul-weather traction but also eerily competent handling performance on dry roads.

    Acura, for instance, has offered its Super Handling All-Wheel-Drive (SH-AWD) system for several years. It monitors vehicle speed, wheel speed, gear position, steering angle, yaw rate, lateral G forces and other inputs, while automatically adding torque to the outside rear wheel in corners to make the car turn quicker. A set of electromagnetic clutches in the rear differential passes the torque from side to side. The system, which normally distributes torque 90 percent up front and 10 percent in the rear, quickly changes to a 50/50 split during acceleration or hard cornering. The system can then send some or all of that 50 percent going to the rear axle directly to the outside tire to make the vehicle bend into a corner more sharply. Mitsubishi, a torque vectoring pioneer, has used a similar system called Active Yaw Control in the rear axle of its high-performance Evolution sport sedan since the late ’90s.

    Audi, BMW and others are taking it a step further: While SH-AWD only works on the rear axle of a normally front-drive vehicle, new systems from automotive suppliers Ricardo in Britain and ZF in Germany can vector torque to all four tires simultaneously.

    The Ricardo Cross-Axle Torque-Vectoring system uses wet clutches and planetary gearsets, in both the front and rear differentials, that are controlled by electrical, electromechanical or electrohydraulic control systems. Ricardo says the system’s response time, from the push of the accelerator to the delivery of up to 90 percent of available torque, is only about 0.1 seconds. If Ricardo’s vectoring is used only in an all-wheel-drive vehicle’s center differential, the engine torque effectively gets passed around front-to-rear and side-to-side—with split-second accuracy—for every driving condition. Look for it in the new Audi A4 and A5.

    German transmission and driveline company ZF has also developed a torque-vectoring system, called Vector Drive—and it’s ready for volume production in all-wheel and rear-wheel drive vehicles. The system distributes drive torque individually to each of the rear wheels, generating a yaw movement around the vertical axis. This improves both cornering performance and vehicle stability in less-than-ideal road conditions. When driving straight, the torque vectoring rear axle behaves like an ordinary open differential. Drive torque is distributed equally to the wheels. Torque is only distributed individually along both halfshafts on an axle during cornering, controlled by an electromechanically actuated multi-disk brake. The ZF system also generates wheel differential torque independently of the drive torque. When cornering through a downhill section off the throttle, the outer wheel receives more drive torque than the inner wheel, allowing crisper turn-in. The gears of the planetary gearset don’t turn when driving straight, so the system saves fuel too. The torque-vectoring drive also acts like a positive-traction or locking differential on dry or uneven traction startups, with torque going to the wheel with higher friction potential.

    These new torque vectoring systems will undoubtedly join forces with the pre-existing ABS brakes, traction control, stability control, steering and rollover mitigation systems. The result will be smarter, safer and quicker vehicles, whether it’s on a rain-soaked freeway, a snowy driveway or a racetrack. —Jim McCraw

    I'll take a torque-vectoring capable 335xi!

  • hi OW, just read the press release on the 335 software pkg by dinan, wow there is some significant extra pony & torque stuff going on here.

    thinking that my 335xi will definitley be a, ultimate awd sedan, soon enough.

    safe & fun driving.
