Like the E 400 that was launched last year, the SL 400 will be powered by a twin-turbocharged 3.0 litre petrol V6 producing 245kW and 480Nm, increases of 20kW and 110Nm over the SL 350's 3.5 litre V6.
And with the move to turbocharging comes greater low-end torque, with the SL 400 producing peak torque from between 1600 and 4000rpm. Consequently the 0-100km/h sprint is slashed from 5.9 seconds to just 5.2 seconds.
Downsizing the engine also benefits fuel economy. Mercedes-Benz claims the SL 400 needs just 7.3 l/100km on the combined cycle, which is 1.1 l/100km less than the SL 350 despite producing more power and torque.
The SL 400's local debut is set for the third quarter of this year.
Pricing is still to be confirmed, however Mercedes-Benz Australia's Jerry Stamoulis told TMR today that the new model is likely to stay close to the $227,000 list price of the current SL 350.
