Engine & Performance
It is powered by a 2.0 liter TFSL engine which produces 295 pound feet of torque and 310 horsepower. The power allows it to hit 62 mph in 4.2 seconds, to go with the top speed of 174 mph.
All these are aided by a lithium-ion starter battery and a power-to-weight ratio of 3.6 kilograms per horsepower which is in line with many performance oriented sports cars. The lithium-ion starter battery is much lighter and smaller than the standard lead battery.
The interior is designed in a way to reduce excess weight. Carbon fiber has been used in the cabin, the center console, the door trim and the cross-bracing which replaces the rear seat-bench.
Audi TT ultra Quattro Concept makes use of a simpler and a lighter suspension system-unit. This shaves off some weight from the current set-up improving comfort and handling. The coil springs which were traditionally made from steel have been replaced now with fiberglass reinforced plastic. This shaves of 40% of their bulk and still maintaining the overall usefulness.
The engine modifications to the crankshaft, the crankcase, the balancer shafts, the oil sump and bolts have been made lighter by 25 kilograms (55 pounds).
The spokes are made of high-strength aluminum bolted to the wheel directly. This reduces weight by 20 kilograms (44 lbs).
