[Diesel Style] MB SL400 CDI and SLK 320 CDI Triturbo.
-
The SLK 320 CDI tri-turbo is based on the new V6 diesel engine, which achieves new levels of performance thanks to a two-stage supercharging system. It consists of three turbochargers, of which two are located on the outside next to the cylinder banks while the larger third turbocharger is situated between the V of the cylinders. At low engine speeds and loads, air flows through all three turbochargers (i.e., large and small), with the small turbochargers doing most of the work.
When engine speed increases and the flow is continuous, the large turbocharger takes over supplying the greatest share of the charge pressure and the smaller turbochargers are turned off by means of a bypass system. At high engine speeds and loads, only the large turbocharger is running. Performance is further heightened as a result of an enlarged intercooler and larger pipe diameters for the charge air and the exhaust.
Sporting a modified tachometer with a red zone extending from 4,500 to 5,000 rpm and the self-confident appearance of the SLK 55 AMG, the vehicle is a proud member of the Mercedes-Benz diesel family. The new engine gives the roadster an impressive boost and allows it to perform prodigious feats: It takes the car but 5.3 seconds to accelerate from 0 to 100 km/h, and it can travel a distance of 1,000 metres in just 24.4 seconds from a standing start.
The top speed is meanwhile electronically limited to 250 km/h. With this kind of performance, the SLK 320 CDI tri-turbo has a unique standing even among thoroughbred sports cars. And fuel economy is just as impressive, since, despite the incredible driving performance, the diesel roadster consumes only 7.5 litres of fuel per 100 kilometres (NEDC overall consumption).

A new V8 engine generates 315 hp in the Vision SL 400 CDI and provides the eight-cylinderÂ’s crankshaft with an outstanding torque of 730 Nm.
The new drive in the Vision SL 400 CDI also belongs to Mercedes-BenzÂ’ third generation of CDI engines. To create this system, the engineers took the familiar four-litre V8 diesel and enhanced many of its components while also adding state-of-the-art piezo injectors, new turbochargers and an optimised water/charge-air cooling system. Taken together, all of these measures allow the engine to bring forth its power and torque in an even more harmonious fashion. The SL 400 CDI accelerates from zero to 100 km/h in 5.8 seconds. As such, this diesel sports car justifiably bears the legendary letters SL.

i'm nt suprised....1stly diesel engines have lots of torque and 2ndly they are cleaner and more efficient and more economical than their petrol counterparts...
-
tri-turbo
-
oh my fook... tri turbo..
-
Buggati Veyron is quad turbo...
-
torque is GOOD!
-
would too much torque give too much wheel spin, n resulting in e tires not being able to get off e mark faster?
n i do realise e slk is a tad faster to 60 than e sl.. even wif smaller displacement -
we would not be able to c those in SG right?
probably Brunei i guess, a friend there has a Diseal MX-5... and Galant....
Diseal Power.... -
Ya! Then when go up slopes on Genting Highlands no problem at all.Originally posted by slacker_goh:torque is GOOD! 
But Diesel engine-ed cars think got one prob leh. Diesel engine are noisier. Rmbr hearing the noise of the engine of the taxis when travelling on the expressways? Imagine hearing that noise for a straight 6 hrs journey to KL. Just pray that future diesel cars on SG roads will be as quiet as the Skoda Superb V6 TDI Taxis.

But SG cannot buy...
