The new Audi TT diesel quattro features the same 2.0 TDI engine found in the rest of the TT range. That means a powerful 184PS engine that produces a prodigious 380Nm of torque. The quattro transmission channels this to both axles via an electro-hydraulic, multi-plate clutch, apportioning power depending on numerous factors that can change almost instantaneously, while wheel selective torque provides even more precise control. The outcome is a reduction in the 0-62mph time of 0.4 seconds for the Coupé and 0.3 seconds for the Roadster, with the times now 6.7 seconds and 7.0 seconds respectively. A six-speed S tronic twin-clutch transmission is the only gearbox option for this model, and it perfectly suits the everyday versatility, capability and comfort of the TDI TT with quattro. However, fuel economy has barely been affected, with figures of up to 52.3mpg combined achievable, corresponding to CO2 of 142g/km.
