context_page_description: The R230 generation of the Mercedes-Benz SL-Class was introduced at the 2001 Frankfurt Motor Show and 2001 Bologna Motor Show, replacing the R129. The R230 underwent revisions in 2006 and 2008, and was superseded by the new SL-Class R231 in 2011.
context_section_description: 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.
