What happens when you combine rally heritage, diesel racing technology and a small sports car? If you ask Audi, it will tell you that sounds the perfect recipe for the new 2015 Audi TT 2.0 TDI Ultra.

Yes, I know it’s an obnoxiously long name, but there is a lot of important information in there. First off, the 2015 Audi TT portion lets us know that this is based on the latest and greatest version of Audi’s venerable coupe, the TT. The 2.0 TDI tells us it uses the latest Volkswagen family, common-rail, turbo-diesel engine. The Ultra is the most important part though. Audi has reserved that term for new versions of its cars that are ultra-efficient while still retaining the fun and excitement that the brand is known for.

Considering this little rocket will hit 60 mph in less than seven seconds, reach a top speed of 150 mph and still manage more than 50 mpg, I think Audi has succeeded in its mission. Is this new TT the Ultra choice for frugal fun? Read on to find out more and decide for yourself.

Despite the incredible fuel-economy promises of this machine, it is no slouch in the performance category. The new 2.0-liter diesel engine is good for 130 kW of power and 380 Nm of torque. For those of you in the states, those numbers come out to 184 horsepower and 280 pound-feet of twist; that is a lot in a car this small. It should have similar performance to the new Mk VII GTI as a comparison.

Oh yeah, it comes with a six-speed manual transmission as well.

The only real performance hit for this car is the lack of Quattro AWD. AWD systems add extra weight and drag so they are fuel-economy no-nos. Still, Audi has proven that it can make competent FWD machines, and the TT Ultra should be no different. The Ultra badge for fuel economy does seem quite appropriate as well. The actual consumption figures for this car are 4.2-liters of fuel per 100 kilometers, which works out to be around 56 mpg.

Visually there is very little that will separate the Ultra TT from other models aside form a few small badging changes and what is most likely a more fuel-efficient set of rubber on the wheels. Overall it is hard to find fault with the package that Audi is offering here. If you want something fun and frugal like the Golf GTD, but you want a car that is a little sportier and has a bit more style, the TT Ultra looks to be the best choice right now.

135 kW (184 hp) and 380 Nm (280.3 lb-ft) of torque, the latter between 1,750 and 3,250 rpm – the new 2.0 TDI clean diesel offers ample power for the new Audi TT. The diesel engine accelerates the Coupé from zero to 100 km/h (62.1 mph) in 7.1 seconds en route to a top speed of 241 km/h (149.8 mph). Its average fuel consumption is just 4.2 liters per 100 kilometers (56.0 US mpg), with CO2 emissions of 110 grams per kilometer (177.0 g/mi). Thanks to this high efficiency, the Audi TT 2.0 TDI, which will be available upon launch with a manual transmission and front-wheel drive, bears Audi’s “ultra” label.

The 2.0 TDI clean diesel, whose 1,968-cc displacement is the result of an 81.0‑millimeter (3.2 in) bore and 95.5-millimeter (3.8 in) stroke, has been updated in a number of areas. The balance shafts now rotate in the crankcase and are mounted on roller bearings. The reduced piston ring tension also helps to reduce friction. The valve train is a separate module with a stiff and lightweight frame for the camshafts. The valve star is rotated 90 degrees. The two camshafts are mounted on needle bearings and actuate one intake and one exhaust valve per cylinder. The intake camshaft can be adjusted by up to 50 degrees of crank angle.

The developers also took great pains with respect to thermal management. The crankcase and cylinder head have separate coolant loops with independent controllers. During the warmup phase, only one so-called microloop is active so that the engine block warms up quickly. The oil pump operates at one of two pressure stages as needed, thus saving drive energy.

The common rail system injects fuel at up to 2,000 bar via eight-hole nozzles. The high pressure enables fine nebulization and thus efficient, low-emission combustion. The turbocharger has adjustable vanes on the turbine wheel and features an updated pneumatic actuation system. The charge air intercooler is located in the intake manifold module, resulting not only in a compact package but also short gas paths, spontaneous response, good control quality and high efficiency.

The DeNOx storage catalytic converter and diesel particulate filter have also been updated. They are located in the immediate vicinity of the engine. The shortened gas paths improve the response of the emissions control system considerably. The new assembly includes the connection for the low-pressure exhaust gas recirculation system, which minimizes pressure losses.
