Everything has its time and with the world changing as rapidly as it does these days it never takes too long for something to become obsolete. The current trend in the automotive industry is one of turbocharging, not just for performance, but also emissions. Strict European laws that come into force soon will see the majority of naturally aspirated engines as too polluting. However, sometimes with change comes good things and that is certainly the case for the Mercedes-Benz SL 400. New Twin-Turbo V6 for Mercedes-Benz SL.
The Mercedes-Benz SL 400 replaces the 3.5 litre naturally aspirated V6 SL 350 model. Underneath this revised cars long bonnet now sits a 3.0 litre twin-turbo V6 unit. Although it is down on overall capacity, the new engine produces 328BHP and 354lb ft of torque. That is enough to get the new SL from 0-62MPH in 5.3 seconds, 0.7 seconds faster than the outgoing SL 350. Fuel economy is stated at 39MPG combined emitting 172g/km CO2 making this car faster, cleaner and more fuel efficient than option it replaces. Top speed is electronically limited to 155MPH.
