Audi has taken away the headlines again with the TT Ultra Quattro concept car ahead of the annual gathering at Worthersee, Germany which is expected to be at early May. The Audi’s TT sports coupe was first launched in 1995 at Frankurt motor show. The car had mechanical and engineering advantages. To add to the car’s glory now the Audi engineers have worked on reducing the weight of the car up to an impressive 300 kgs.
The loss of the weight of the car has been due to a large set of reasons but the main reason being the all- aluminium chassis. The car now weighs 1,111 kgs and makes a power to weight ratio of around 275 hp per ton. Powered by the four cylinder engine the car can produce 305 bhp power and can accelerate to 100 kms from stand still at 4.2 seconds. The top speed of the car is about 273 kmph. As the name reveals, TT Ultra Quattro is an all wheel drive from Audi.
The designers had modified several body parts such as the crankcase, crankshaft, balancer shaft, fly wheel, sump bolts and other parts which had reduced the weight of the engine by 25 kgs. The other detachable body parts contribute to the weight loss by nearly 100 kgs. The car had used Carbon fibre reinforced polymer (CFRP) in rear end, centre tunnel and B pillars of the car, which also reduces the overall weight of the car. Adding to this are the magnesium components on the floor and hinges of the car.
TT Ultra has used Fibre glass reinforced polymer coil for the springs in the suspension instead of the steel coils used in normal suspensions. They are made by long glass fibres, twisted together and impregnated by epoxy resins.
Every single detail of the car proves the engineers’ aspiration to reduce the car’s weight and make it super fast.
