The svelte Mercedes-Benz CLS has long been a favorite of tuners, and with the new model on the way, you can expect a veritable onslaught to ensue. The first bit of blood has been drawn by Carlsson, which has just unveiled its tuning program for the CLS350 before it even reaches showrooms.

Engine modifications are available for both the CLS350 gasoline and diesel V6 mills. With the petrol engine, power is increased to 333 horsepower and 302 pound-feet of torque (gains of 27 and 29, respectively), and the oil-burning powerplant now cranks out 320 hp and 575 lb-ft (increases of 55 hp and 96 lb-ft). Both the gasoline and diesel CLS350s will sprint to 62 miles per hour in just 5.9 seconds – 0.2 seconds faster than the stock petrol car and 0.3 seconds faster than the standard diesel model.

Carlsson's C-Tronic adjustable suspension (mounted to a choice of wheel options) is also on offer, as is a full body kit – complete with a new front bumper, grille, power-dome hood, LED fog lamps, side skirts, side vents and rear apron with diffuser – and an Alcantara and brushed aluminum-trimmed interior.
