The Mercedes-Benz E 300 BlueTEC diesel-electric hybrid, capable of achieving 65.7 mpg with emissions of 109g/km of CO 2 , will cost £39,645 when it goes on sale in November 2012.
There will also be an E 300 BlueTEC Hybrid Estate which will start at £41,435.00. The BIK rates range from 12 per cent.
Standard equipment includes 17-inch alloy wheels, although 16-inch wheels can be fitted as a no-cost option to achieve the lowest possible CO 2 and economy figures. Also included is leather upholstery, Becker Map Pilot Navigation and LED daytime running lights.
The E 300 BlueTEC Hybrid brings together a powerful yet highly efficient 2,143cc, four-cylinder diesel engine. Developing 204 hp and 500 Nm of torque, it is linked to a 20 kW electric motor mounted within the 7G-Tronic Plus automatic transmission powered by a 19kW Lithium-ion battery.
The result is the ability to accelerate from rest to 62 mph in 7.5-seconds (Estate: 7.8-seconds) before reaching a maximum speed of 150 mph (144 mph) when required. When fitted with the 16-inch wheels, the E 300 BlueTEC Hybrid is capable of returning 65.7 mpg (62.8 mpg) on the combined cycle while emitting as little as 109 g/km of CO 2 (116 g/km).
The Hybrid system is packaged within the vehicle so as not to impact on the versatility or load capacity of the E-Class in any way. The electric motor, for instance, is mounted within the 7G-TRONIC PLUS automatic transmission. The gearbox substitutes a torque converter for a wet clutch system, therefore allowing for the internal combustion engine to be disengaged entirely via the clutch and for electric-only drive to be maintained for short periods, boosting economy.
UK deliveries of the new E 300 BlueTEC Hybrid are due to start in November.
