German automaker Audi recently detailed the 2015 TT Roadster ahead of the 2014 Paris Motor Show. Currently in its third-generation, the TT and TT S will come with features such as an advanced new chassis, digital instrument panel and an updated Quattro drive system.
Future tech embodies the new TT as it utilizes an updated Audi Space Frame (ASF). Ultra-high strength steel fortifies the front section of the car and the cabin floor while semi-finished aluminum is used for the cabin frame and outer skin. To provide simultaneous lightness and rigidity, the aluminum A-pillars are hollowed out and house a solid steel tube, V-shaped steel struts bolster the zones beneath the engine and luggage compartment while also connecting the axle carriers. Overall, the weight of a gas-powered TT Roadster with the 2.0 TFSi engine and manual gearbox only tips the scale at 1,320 kg. Moreover, the shape and construction of the car provides a best-in-class drag coefficient of 0.30 cd.
The body of the new TT measures 4177mm long, 1832mm wide and 1355mm high. It has a wheelbase of 2505mm which is 37mm longer than the predecessor, provides shorter overhangs and gives it a more purposeful stance according to Audi. At the front, the car features a single-frame grill reminiscent of the R8, LED DRLs and headlights that are available with either LED or HID lighting. An optional Matrix LED headlight system that automatically adjusts the beams onto oncoming or leading traffic comes optional. At the rear, the LED taillights are permanently illuminated while the 3rd brake light is placed inside the trunk lid-connecting the light silhouette at the rear. A diffuser is integrated on the exhaust system while a spoiler placed on the decklid automatically extends at speeds of 120 km/h and beyond.
The electronically-controlled retractable roof is made out of snug fabric and comes in a selection of colors including black, beige and titanium gray. The inner headlining comes standard with a thick fleece layer which provides comfort as well as reducing interior noise levels by up to 6db compared to the previous TT roadster. Holding it all together is a frame made out of magnesium, aluminum, steel and plastic that weighs at 39 kg, 3 kg less than the previous model. It can be operated of up to speeds of 50 km/h and will open or close in just 10 seconds. The roof sits on an aluminum tray inside the trunk so it does not lessen the standard 280 liter space and a special wind deflector can be specified upon ordering.
Inside, both cars will feature Audi's own virtual cockpit that uses a 12.3-inch LCD screen which replaces the traditional analog gauges. The driver can select 2 modes; classic view which shows the speedometer and rev counter, and infotainment which minimizes the speedometer and tachometer and frees up space that displays navigation, outside temperature, time, mileage and warning or information symbols. Alcantara and leather decorate the seats and interior trim while select color accents festoon the sides of the center console and rings of the air vents. Those that need connectivity on the go will find the optional Technology Package as a must. Not only does it provide navigation via HDD, it also provides Internet to the car by way of Audi Connect which uses the latest LTE technology.
Powering the standard Audi TT are a choice of 2 engines, the first of which is a 2.0-liter TDI engine that produces 184 PS with 380 Nm of torque and is mated to a 6-speed manual gearbox. It has an average fuel consumption of 27.9 km/l and only puts out 114 g of CO2 per km. The second engine is the 2.0-liter TFSI engine that cranks out 230 PS with 370 Nm of torque and is also connected to a 6-speed manual gearbox. No fuel consumption average was given by Audi for the TFSI engine. In the TT S Roadster, power is also provided by the 2.0-liter TFSI engine but this one produces 310 PS and 380 Nm of torque. It is connected to either a 6-speed manual or onto a 6-speed S-tronic twin-clutch transmission and has a governed top speed of 250 km/h. Both cars can be ordered as FWD or AWD.
