Starting in September, Mercedes-Benz will offer its sporty SLK Roadster with a diesel engine, the automaker’s first such offering.  The SLK Roadster has been on the market since 1996 and currently has three petrol variants, the SLK 200, SLK 250 and SLK 350.

The new SLK 250 CDI comes standard with the 7G-Tronic Plus automatic transmission and is powered by a 2143 cc four-cylinder diesel engine producing 204 hp. Thanks to its 368 pound-feet (500 Nm) of torque, the SLK 250 CDI accelerates from 0-100 km/h (0-60 mph) in 6.7 seconds and has a top speed of 243 km/h (151 mph).  It can go from 80 to 120 km/h (50 to 75 mph) in just 4.3 seconds.

The option of a six-speed manual transmission will follow in the second quarter of 2012.

The new Mercedes-Benz SLK 250 CDI will be available for order in Germany and certain other markets starting in mid September.  Once available, it will not only be the most efficient model in its class but it is likely to be the most powerful as well. Put differently, it will be a true two seater sports car with the fuel economy of a sub-compact.

The diesel engine is representative of latest Mercedes-Benz’ latest diesel technology.  This includes fourth generation common-rail fuel injection with a rail pressure of 2000 bar and precise injection timing as well as a two-stage turbocharger and auto start/stop system.

Mercedes-Benz rates the fuel economy of the new SLK 250 CDI at 4.9 liters per 100 kilometer (48 mpg US, 57 mpg Imperial) in the EU test cycle (a combination of city, highway and extra-urban driving). According to Mercedes, the SLK 250 CDI can go from the North Sea to a Mediterranean beach on one tank of fuel.

Appearance-wise, the SLK looks just like its petrol-powered brethren.  It has the same twin exhaust system, a choice of thre suspensions, and also comes with a choice of three versions of the vario roof.  When it goes on sale, the price (including VAT) will be € 41,828.50.
