The facelifted SL model was revealed in the Geneva Motor Show in March 2008.
The SL received a new, more aggressive front end reflecting Mercedes's new design philosophy, with a pair of long powerdomes on the bonnet and a single-bar grille replacing the old three-bar effort.
Improvements have been made also on the engines.
The 3.5L V6 is uprated to 311 PS (229 kW; 307 hp) at 6500 rpm.
Compared to the previous 3.5-litre engine, the output has been boosted by 16 percent.
Torque has also been improved adding 10 N⋅m (7.4 lb⋅ft) to the previous 350 N⋅m (258 lbf⋅ft) making it 360 N⋅m (266 lbf⋅ft).
This engine now can rev up to a max of 7200 rpm for a period as the oil temperature and other engine parameters permit, a higher compression ratio, a new intake manifold and featuring extensive modifications to and lightening of the valve train.
In this case, however, the extra power does not come at the expense of fuel economy: with a consumption figure of 9.9 litres per 100 kilometres, the new SL 350 undercuts the previous model developing 200 kW (272 PS; 268 hp) by 0.4 litres per 100 kilometres.
Mercedes-Benz is extending the SL-Class line-up by introducing an attractive entry-level model in the shape of the SL 280 developing 170 kW (231 PS; 228 hp).
The six cylinder powerplant delivers its peak torque of 300 N⋅m (221 lbf⋅ft) from 2500 rpm and accelerates the roadster from 0 to 100 km/h (62 mph) in 7.8 seconds, whilst fuel consumption (NEDC) is just 9.4 L/100 km (30 mpg‑imp; 25 mpg‑US).
It features the AIRSCARF heating system used in the SLK.
