It’s a concept, a one-off prototype but it doesn’t look much new. This is an Audi TT, a model that’s been around for several years, but this concept is significantly different from the TT the dealers have. This car has some pretty incredible technology. Its coils springs, made of quality steel on all cars, are built out of fiberglass-reinforced plastic. The battery is lithium-ion, it weighs less than four kilograms (8.82 lb). And the list goes on. Front brakes feature ceramic disks with an aluminum fixed caliber. The exhaust system is made out of titanium, and the wheels have their spokes made out of high-strength aluminum which are bolted directly to the carbon fiber reinforced plastic (CFRP) wheel.
With a lot of work on the body structure, on all body parts, and pretty much everywhere, the engineers have managed to shed an incredible 300 kilograms (662 lb). The result is a car weighing only 1,111 kg (2,449.34 lb). With a 2-liter TFSI 228 kW (310 hp) engine under the hood, performance is very strong.
From a standstill, the TT ultra quattro concept goes to 100 kph (62 mph) in 4.2 seconds, and top speed is 280 kph (173.98 mph). Sadly, Audi doesn’t say anything about fuel consumption, but we can also expect amazing progress here. Let’s hope all this work will make the next generation of TT even better.
