The SL-Class range is set for a power hike as a series of revisions are announced. The new SL 400 Sport will join the SL family replacing the SL 350 as the entry model to the range and the SL 63 AMG will gain even more power. Fitted with a V6 biturbo drivetrain the SL 400 features an increase of 27 hp and 110 Nm of torque over the outgoing engine and is quicker, despite displacement being decreased by half a litre. The SL 400 will be available from £72,500 OTR and deliveries will start in July. A total of 333 hp and 480 Nm of torque are produced by the all-new six-cylinder engine equipped with two turbochargers lowering the 0-62 sprint from 5.9 to 5.2 seconds. This combination ensures that the automotive icon meets EU6 emissions standards, whilst also ensuring that customers have the very best in style, power and performance.
