The Audi TT 1.8 TFSI weighs a mere 1,240 kg (2,733.73 lb), a good 100 kilograms (220.46 lbs) less than its closest competitor. The body of the Coupés weighs only 206 kilograms (454.15 lb), which breaks down to 140 kilograms (308.65 lb) of aluminum (68 percent) and 66 kilograms (145.51 lb) of steel (32 percent). The specific reinforcements in the TT Roadster - steel bulkhead, strongly ribbed sills, A-pillar and windshield frame - result in a 58 to 42 percent split of the two materials.
