Latest Audi common rail diesel engine blends torque-rich sports car punch and extraordinary efficiency in latest TT models.
Acclaimed Audi TT Coupé and Roadster models adopt a diesel engine for the first time in their 10-year history
World public debut at the Geneva Palexpo (March 6th to 16th 2008)
Powered by the latest 2.0-litre, four-cylinder TDI engine with
ultra-efficient common rail fuel injection incorporating piezo injectors
Already compliant with proposed Euro 5 emissions legislation, and over 20 per cent more CO2-efficient than petrol equivalent
170PS at 4,200rpm, 350Nm from 1,750rpm to 2,500rpm
TT TDI Coupe 0-62mph in 7.5 seconds, top speed 140mph, 53.3mpg combined consumption, CO2 140g/km
TT TDI Roadster 0-62mph in 7.7 seconds, top speed 138mph, 51.3mpg combined consumption, CO2 145g/km
The world’s first bona fide diesel-powered sports car - the new 140mph
Audi TT 2.0 TDI quattro - brings 50mpg-plus fuel economy, a 23 per cent
reduction in CO2 output and EU5 compliance to the 2008 Geneva Motor
Show (March 6th to 16th). Far from being just a flight of fancy, the
latest TT is fully production-ready, and opens for European order in Coupe
and Roadster body styles in March.
First deliveries are expected in summer 2008.
The ideal TT TDI engine, which not only had to complement the
much-loved character of the TT but also had to fit transversely into
its compact engine bay, arrived recently in the space-efficient shape
of the latest 2.0-litre, four-cylinder TDI with performance and
refinement-boosting common rail fuel injection incorporating advanced
piezo injection technology. Launched to critical acclaim in the new A4
Saloon in 143PS form, the economical new powerhouse transfers to the TT
with an upgrade to 170PS, and an impressive 350Nm maximum torque output
– more than even the 3.2-litre V6 petrol model can muster.
Spurred on by a new turbo charger with adjustable vanes that allow rapid torque build-up, and by the sophisticated common rail injection system, whose advanced piezo injector nozzles can perform up to five distinct injection sequences per cycle, the new engine offers more than enough performance to dispel any lingering doubts about sports car compatibility.
Spinning freely to its 5,000rpm limit, and doing so without fuss thanks not only to its high-tech injection technology but also to refinement-boosting balancer shafts, the TT 2.0 TDI quattro Coupe with six-speed manual transmission takes just 7.5 seconds to reach 62mph. A top speed of 140mph is possible where conditions allow, and the stamina-building influence of TDI is made abundantly clear by a combined consumption figure of 53.3mpg.
The stride forward in efficiency over the outgoing 2.0-litre TDI engine also shows in a CO2 figure of 140g/km for the Coupé - over 20 per cent less than the 2.0 TFSI petrol model - and in a drastic reduction in untreated emissions of oxides of nitrogen. Improvements in combustion chamber thermodynamics mean the new engine can run on up to 60 per cent recycled exhaust that has been cooled by the radiator, and ensure the 2.0 TDI already complies with proposed Euro 5 emission limits.
Lightweight Audi Space Frame (ASF)
The impressive all-round performance of the new TT 2.0 TDI quattro is also due in no small part to its lightweight Audi Space Frame aluminium and steel hybrid body shell, which contributes to impressively low kerb weights of 1,370kg for the TT 2.0 TDI quattro Coupe and 1,415kg for the TT 2.0 TDI quattro Roadster.
The undivided attention to weight-saving also proves its worth in the comfort of the TT’s ride and the nimbleness of its handling, which in the best traditions of all higher-torque sporting Audis is backed up by quattro permanent four-wheel-drive. The space-age Audi magnetic ride adaptive damping system, employing specially developed dampers filled with a magnetic fluid that reacts to an electrical charge, will also be available as an option for driving enthusiasts who want to extract the very best from the sophisticated aluminium-rich suspension.
Standard specification for the new TT 2.0 TDI quattro mirrors the familiar 2.0 TFSI petrol version, offering features such as 17-inch Trapez alloy wheels, leather and Alcantara-upholstered sports seats, electronic climate control and an MP3-compatible 140-watt Audi Concert audio system with single CD drive. The Roadster adds a fully automatic electrically operated soft-top and integrated wind deflector.
