2012 Mercedes-Benz SLK 250 CDI: official details, photos, specs and price

Article by Christian A., on August 16, 2011

A diesel engine has recently been added to Mercedes-Benz’s sporty SLK Roadster range. Orders for the new SLK 250 CDI will be taken by the automaker starting on September 13. The model retails for EUR41,828.50 (inclusive of VAT). The new Mercedes SLK 250 CDI retains the twin exhaust system and looks exactly the same as the petrol models.

The four-cylinder diesel engine with a displacement of 2143 cc delivers 204hp and 500 newton metres of torque. This is the same output level as a petrol engine but with twice the displacement that it would typically produce.

This engine is coupled to a standard 7G-TRONIC PLUS automatic transmission. By the second quarter of 2012, a six-speed manual transmission is expected to follow. The car is capable of going from a standstill to 100km/h in 6.7 seconds and from 80 to 120 km/h in only 4.3 seconds.

It can hit a top speed of 243 km/h. The SLK 250 CDI has a fuel economy rating of 4.9 l/100km, while it has CO2 emissions of just 128 g/km. The SLK 250 CDI is offered with a choice of three versions of the vario-roof, one of which is the panoramic vario-roof with MAGIC SKY CONTROL.

At a single click on a button, the glass roof can be switched from dark to transparent. Three suspension versions are offered, namely: a conventional steel suspension, a sports suspension with a stiffer spring and damper setup or a suspension with an electronically controlled, fully automatic damping system. This system is actually included in the Dynamic Handling package, which features the Direct-Steer system and the Torque Vectoring Brake.

The Mercedes Benz SLK250 CDI diesel variant is just as exciting as the way it looks. Thanks to its highly sophisticated diesel engine, the SLK250 CDI offers an impressively smooth driving, fuel economy and powerful output.

The engine is equipped with 2-stage turbocharging technology along with highly efficient 4th generation common-rail injection timing, for better combustion. Meanwhile, the common rail system’s pressure bar is up to 2000 for a cleaner, more powerful fuel performance.

Travel from A to Z with the Twin-Turbo diesel’s amazingly low fuel consumption. The very comfy sports seats and superior suspensions bring luxury, comfort and convenience to all the passengers. But that’s not all. The same variant has the most spacious compartment in the entire segment, since it is designed for the longest out-of-town road trips ever imagined.

On the other hand, the Vario roof technology comes in three different versions. The most remarkable among the three is the panoramic glass roof with Magic Sky Control system. The sunroof automatically transitions from clear to dark (or reverse) with just a tap.

For the suspension, there’s a choice between the fully automatic damping system and the electronically controlled one, aside from the sports version and the conventional steel suspension system. The sport suspension is part of the Mercedes Benz SLK’s dynamic Handling bundle that goes well with its Torque Vectoring Brake and Direct-Steer technology.

High end driving has clearly changed over the years. In other words, this extraordinary variant has the same sporty feel and stunning design of a Mercedes Benz SLK series but with the CDI 250 diesel, it’s so much better. That’s basically since the diesel engine has earned its own reputation when it comes to fuel economy. Therefore, the SLK250 CDI is more practical for everyday use while not putting the driving performance on the backseat.

The new SLK 250 CDI: Sports car performance with the fuel economy of a sub-compact

For the first time, Mercedes-Benz is offering the sporty SLK Roadster with a diesel engine. The 150 kW (204 hp) four-cylinder power unit puts the two-seater at the top of its class in numerous respects. With a fuel consumption of 4.9 litres per 100 kilometres, it is the most economical roadster in its segment. Thanks to its enormous torque of 500 newton metres it accelerates from zero to 100 km/h in 6.7 seconds, and delivers a top figure for acceleration from 80 to 120 km/h. The result is superior driving enjoyment both on winding country roads and on long motorway stretches. Like the other models in the latest SLK family, which was presented in January 2011, it combines lively sportiness with high-quality appointments and excellent comfort.

Diesel drive and roadster excitement do not go together - or so a common misconception would have it. Mercedes-Benz impressively demonstrates the contrary with the new Mercedes-Benz SLK250 CDI. Its four-cylinder diesel engine with a displacement of 2143 cc generates an output of 150 kW (204 hp) and 500 newton metres of torque - as much as a petrol engine with twice the displacement would normally generate. This makes the new Mercedes-Benz SLK250 CDI the most powerful diesel model in its class, and gives the roadster the potential for extremely sporty performance.

Equipped with the standard 7G-TRONIC PLUS automatic transmission (a six-speed manual transmission will follow in the second quarter of 2012), the diesel SLK sprints from zero to 100km/h in 6.7 seconds and achieves a top speed of 243 km/h. Moreover, the flexibility of the Mercedes-Benz SLK250 CDI is nothing short of phenomenal. Thanks to its enormous diesel torque it accelerates from 80 to 120 km/h in just 4.3 seconds - easily the best figure in this class, making for safe and effortless overtaking.

Apart from this, the Mercedes-Benz SLK250 CDI is the most economical and therefore environmentally compatible roadster in its segment. It is happy with 4.9 litres of diesel fuel per 100 kilometres (NEDC combined consumption), which corresponds to CO2 emissions of 128 g/km. In other words, the diesel SLK combines thoroughbred sports car performance with the fuel economy of a sub-compact. This guarantees great driving pleasure with great fuel efficiency.

The diesel engine achieves its exemplary output, torque, fuel consumption and emissions figures, as well as its highly impressive smoothness for a diesel unit, thanks to an extensive package of innovative technologies. These include fourth-generation common-rail injection with a rail pressure of 2000 bar and precise injection timing, as well as two-stage turbocharging. Like all SLK models, the Mercedes-Benz SLK250 CDI also features a start/stop system as standard.

The frugal fuel consumption makes the Mercedes-Benz SLK250 CDI a car with superior long-distance qualities. Using the European motorways, it is e.g. quite possible to drive from the North Sea to a beach on the Mediterranean non-stop. Very comfortable sports seats, a comfortable suspension setup and the largest luggage capacity in this segment also do their bit to create the right conditions.

As it shares the same genes with the other members of the successful SLK family, the Mercedes-Benz SLK250 CDI combines lightfooted sportiness with stylish comfort, a striking sports car design and absolute day-to-day suitability, while delivering top performance with exemplary ecology. This means that the diesel version too provides open-top driving enjoyment at an extraordinarily high level.

The Mercedes-Benz SLK250 CDI is likewise available with a choice of three versions of the famous vario-roof - one of them the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof can be changed from dark to transparent at the touch of a button. There are also three suspension versions available: a conventional steel suspension, a sports suspension with a stiffer spring and damper setup or a suspension with an electronically controlled, fully automatic damping system. The latter is part of the Dynamic Handling package, which also includes the Direct-Steer system and the Torque Vectoring Brake developed by Mercedes-Benz for particularly agile and predictable handling characteristics.

Externally the new Mercedes-Benz SLK250 CDI is no different in appearance from the petrol models. It even retains the twin exhaust system, and therefore has the same exciting look for which all the SLK models are known.

The new Mercedes-Benz SLK250 CDI can be ordered from 13 September 2011. The price including VAT is € 41,828.50.
