We’ve already mentioned the new biturbo V8s slated for the next generation of CL-Class and S-Class models, but Mercedes-Benz has released details about the remainder of the fuel efficient offerings for its new ranges.
New engines for next big Mercs
A series of smaller and more efficient, but also more powerful engines will debut on the carmaker's new range-toppers.
The S350 Blue Efficiency uses a new 3.5-litre naturally aspirated V6 engine with increases in output from 200 kW and 350 Nm to 225 kW and 370 Nm. Despite increases in its output, the engine consumes 7.6 l/100 km and emits 177 g/km of CO2; figures Mercedes claims make it the most economical petrol-powered model in its class.
The S350 Blue Efficiency is complemented by a new 3.0-litre turbodiesel engine. The new 190 kW engine, with an AdBlue emission control function as standard, emits 177 g/km of CO2 while slurping only 6.8 l/100 km. This, Mercedes-Benz says, is the most fuel-efficient S-Class of all time.
Generally, the new direct injection engines employed are claimed to have outputs higher by up to 12.5% and fuel consumption reduced by as much as 24%.
Features such as Blue Direct, a third-generation direct petrol injection system, standard start/stop function and a new 7G-Tronic Plus seven-speed automatic transmission are credited by the carmaker for some of the fuel savings.
In stark contrast, Mercedes-Benz will continue to cater to the power-hungry with a new 320 kW biturbo V8 in the S 500 and CL 500 Blue Efficiency models and a new 380 kW biturbo V12 for the S 600 and CL 600, which remains the pinnacle of the range.
The S-Class and CL-Class coupe should arrive in South Africa from early in 2011.
