Mercedes-Benz reveals 39mpg SL 400

Mercedes-Benz SL 400Mercedes-Benz has revealed the new SL 400 – a 333hp variant capable of 0-62mph in 5.2 seconds and 38.6mpg.

The SL 400 also boasts 354lb ft of torque, a hefty 81lb ft more than the outgoing SL 350 (and it’s 27hp more powerful too). How does it do this? Courtesy of a new 3.0-litre six-cylinder biturbo engine.

The new engine is half a litre smaller than the outgoing motor, but the twin turbochargers makes up the shortfall – and its fuel efficiency is combined with emissions low enough to hit the Euro 6 standard.

The BlueDIRECT engine has direct injection running at 200 bar, Piezo injectors (with up to five injections per stroke) and MSI multi-spark ignition: Mercedes says it delivers up to four sparks within a millisecond, “creating a plasma with a larger spatial expansion than conventional ignition”.

In English, this means every drop of fuel is used better, and emissions are minimised.

The Mercedes-Benz SL 400 replaces the SL 350 from now in Germany with local prices starting at around £80,500. Over here, the current SL 350 costs £69,965; it will be interesting to see where the SL 400 is pitched when it arrives in the UK – note, the SL 500 costs £79,985…

Mercedes will reveal prices and launch date for the new SL 400 in due course.
