Most speed limits are more theoretical in Europe, where mostly high-profile, high-speed and evidenced by the collapse of hot Audi TT appeared to be a problem. Last month we reported on Audi vehicles to a recall were performed and significant limits that are essentially the point where the character starts to feel closer to expanding the use of the vehicle of a sedan tried to soften.
The engineers continued to defend the vehicle's original chassis settings, while quietly, rear axle, lifting the rear spoiler to reduce lift, which is the Prime source of the problems they offered. Spoiler stylists resisted.
Audi's chassis development chief Dr. Bernd Heising, "there was much discussion during development, we have decided not to include it in a spoiler and we all," he admits. "Now, we changed our minds."
As mentioned, the TT is only a problem in Europe because in Germany the main reason of the defects of 80 km / h is the only country where it's legal to pass. A TT driver, was killed a famous highway speed on a curve. A backseat passenger without the belt for a second death occurred. The Audi group reported that the accident investigation had examined the body of 22 Total. This may sound like a lot, but more than 40,000 TTs have been sold worldwide, and apparently the accident rate compatible with the rate of the other sports cars.
Audi, the main goal of the changes increase the level of understeer, lifting is to increase high speed stability and reduce driving. TT Coupe and Roadster, mounting the front control Arms is getting the compatibility of the sign modified. The pitch movement is more rigid and the front and rear seals for compressing during braking to reduce weight transfer to the front is softer against the SAG. Front anti-roll bar rear 1mm smaller in diameter and is made of a millimeter thick.
More precisely, all the TT movement, which aims to reduce the lift on the rear axle at high speeds in a deck is mounted to the door, and small rear spoiler. TT has 148 pounds of lifting capacity on the rear axle 125 in mph without spoiler, but the spoiler is installed, when only 53 pounds of lifting capacity. Compared to this, lifting produces the BMW Z3 Coupe 64 125 pounds mph; Mercedes-Benz SLK, 104 pounds; And Porsche Boxster, 68 pounds the pavement. Chassis engineers claimed that the problem could be solved without the spoiler, but this meant a significant increase in preventing slippage at normal speeds; this was a feature that should be avoided. All the VW TT and switchable electronic stability program (ESP) is getting a version.
Goodyear Luxembourg on the ground and on the surrounding roads to prove the old and new TT rides, and speeds above 100 miles when you use the brake when you change lanes, showed the effectiveness of the changes. No, your situation is not a likely encounter, for the record, does the work of the spoiler, the tail no longer does not give the direction, and stability are much improved. TT, under the circumstances, it gives more confidence now.
At speeds less exciting, highlighting the changes in Routing. Yavaslattiraca affects the way the steering wheel changes the suspension, and therefore more progressive in every nook and wants to return more lock.
Mercedes-Benz Vision SLR and the BMW Z8, two aviation style brake removal and clean the same as a performance car, it seems reasonable to expect that they will need to change to prevent problems. The first pre-production Z8s the shape of pure, but testing near the Nurburgring Spy photos BMW showed a change in the planned use of the car rear spoiler. The people inside the Mercedes Vision SLR concept car to reduce aerodynamic lift at the rear side of the body admits that it has entered into a revision.
