TT Mk2 (Typ 8J, 2006-)
 |
A preview of the second-generation TT was provided in the form of the Audi Shooting Brake concept car, shown at the Tokyo Motor Show in 2005. This concept was an insight into the new TT, but featured angular styling, and a "shooting brake" two-door hatchback body style.
Audi revealed the second-generation TT, internal designation Typ 8J, on 6 April 2006. It is constructed on the Volkswagen Group A5 (PQ35) platform, and uses aluminium in the front bodypanels, and steel in the rear, to enhance its near-neutral front-to-rear weight distribution. It is available in front-wheel drive or 'quattro' four-wheel drive layout, and is again offered as a 2+2 Coupé (TT-C), and as a two-seater Roadster (TT-R). Compared to the previous generation, this new variant is five inches longer and three inches wider than its predecessor. Factory production commenced during August 2006.
8J powertrain
The powertrain options initially only included petrol engines, which consist of either one of two inline four cylinder engines - the all-new 1.8 litre EA888 Turbocharged Fuel Stratified Injection (TFSI) (available initially only in Germany, later elsewhere from mid 2009), or the more common and established EA113-variant 2.0 litre TFSI. The Fuel Stratified Injection (FSI) technology was derived from the Audi Le Mans endurance race cars, and offers improved fuel efficiency as well as an increased power output and cleaner emissions. The 3.2 litre 'V6' badged VR6 engine is carried over from the previous generation, and this engine was also available in the Canadian model. 2.0 TFSI quattro models, with the latestEA888 engine, became available in 2009 model year.
A six-speed manual transmission is standard, with the six-speed Direct-Shift Gearbox (now called 'S tronic' on all Audi models) as an option for all but 1.8 litre engine. quattro on-demand four-wheel drive, again using the Haldex Traction clutch is available - standard on V6 models, but was not available on 1.8 TFSI.
8J suspension & other features
Like all its PQ35 platform-mates, the new 8J TT now has a multi-link fully independent rear suspension to compliment the front independent suspension. The entire suspension system can be enhanced with Audi's new active suspension, "Audi Magnetic Ride", available as an option. This is based on Delphi's MagneRide, which uses magneto rheological dampers (this means that an electronic control unit for the suspension will automatically adjust its damping properties depending on the current road conditions and driving manner).
The new TT also features an revised rear spoiler; which automatically extends at speeds greater than 120 kilometres per hour (75 mph), and retracts again below 80 kilometres per hour (50 mph). The spoiler can also be manually controlled by the driver via a switch on the dash.
2.0 TDI quattro
Launched at the 2008 Geneva Motor Show, Audi offered the first diesel engined version of Audi TT in the European market, the Audi TT 2.0 TDI quattro. As its name indicates, it is only available with quattro, and is also available in Coupé and Roadster versions. Power comes from the new 2.0 litre Turbocharged Direct Injection (TDI) engine, now with 16 valves, double overhead camshaft (DOHC), 1,800-bar (26,110 psi) common rail fuel delivery and eight-hole piezo fuel injectors, which produces a DIN-rated output of 125 kilowatts (170 PS; 168 bhp) at 4,200 revolutions per minute (rpm) and torque of 350 newton metres (258 ft·lbf) at 1,750 to 2,500 rpm. It includes a six-speed manual transmission.
Acceleration from standstill to 100 kilometres per hour (62.1 mph) on the Coupé is reached in 7.5 seconds, and will go on to reach a top speed of 226 kilometres per hour (140.4 mph). The slightly less aerodynamically efficient Roadster reaches 100 km/h in 7.7 seconds, with a top speed of 223 kilometres per hour (138.6 mph).
Audi claim average fuel consumption for the Coupé variant with this 2.0 TDI engine is 5.3 litres per 100 kilometres (53.3 mpg-imp; 44.4 mpg-US), which achieves a CO2 emissions rating of 139 gram/km. The Roadster TDI achieves an average 5.5 litres per 100 kilometres (51.4 mpg-imp; 42.8 mpg-US) and CO2 of 144 gram/km.
