Audi TT ultra quattro Is 300 Kilos Lighter Than TTS
When it comes to automotive performance, lighter is almost always better. Audi is car company not known for emphasizing a low curb weight, as many of its vehicles are packed with the weight of extra luxury features as well as heavy all-wheel drive systems. but it was turned over a new leaf with a recent version of its TT compact coupe. The Audi TT ultra quattro (yes, lowercase letters are a part of its branding) is 300 kilograms lighter than the standard version of the Audi TTS.
Where do the weight-savings come from? The 1,113 kilogram Audi TT ultra quattro makes extensive use of carbon fibre in its body shell, (including the roof, bumpers, wheels, and liftback), and Audi has also redesigned its chassis so as to lop off 50 kilos. Low-mass components are integrated wherever possible, even going so far as to replace rearview mirrors with a camera system and standard brake calipers with aluminium units. The seats inside the car are 20 kilos lighter than stock thrones due to the use of a fibreglass base, and all of the features one would expect in an Audi such as air conditioning and power windows are still present and accounted for.
Why build the Audi TT ultra quattro? This concept car was initially undertaken as an internal study to see how much lighter the TT platform could get, with the intention of eventually porting the lessons learned into the real world. Is also doesn't hurt that the car's lightness improves performance and fuel efficiency (the vehicle is outfitted with a 2.0-liter, turbocharged four-cylinder motor that generates 306 horsepower and 295 lb-ft of torque). It's unlikely that the ultra quattro will make it into production, but the possibility exists of a limited run aimed at collectors and enthusiasts of the brand.
