Outstanding fuel economy is the goal for two new versions launched by Mercedes-Benz for the E-Class, one powered by natural gas and petrol and the other of the diesel variety.
We are now used to seeing smaller but powerful engines on the big models of automakers of today and there should be no surprise the premium brands follow suit. And Mercedes-Benz always had the tradition of delivering especially efficient editions to its models, with frugal figures for the fuel consumption.
The new E 200 Natural Gas Drive can drive on both petrol and natural gas – with benefits from the latter including a smaller acquisition price and a reduction of 20% in CO2 emissions compared to using only petrol. It uses 4.3 kg of natural gas per 100 km (NEDC combined), which corresponds to CO2 emissions of 116 g/km.
The natural gas mode is also kinder to the environment thanks to its cleaner exhaust gases and the car can automatically switch to petrol when it runs out of natural gas, with the newly developed four-cylinder engine needing just 6.3 l/100 km (there is also a start/stop system on board). The engine has 156 hp and 270 Nm, allowing the E model to reach 100 km/h in 10.4 seconds and a top speed of 220 km/h.
With an engine displacement of 2.2 liters, the new E 220 BlueTEC BlueEFFICIENCY Edition uses an extremely fuel-efficient four-cylinder diesel engine with direct injection generating 170 hp and 400 Nm. The special model also features as a standard the 7G-TRONIC PLUS automatic transmission, optimized for maximum comfort and low consumption, aided by the ECO start/stop function.
Other fine tuning includes low-resistance tyres on 16 or 17’’ wheels, the lowering of the chassis by up to 15 mm and a radiator blind that directs the flow of air as required, improving aerodynamics. All this translates into a 4.4 l/100 km fuel consumption, which corresponds to 114 g/km of CO2. This means the model is rated in the best efficiency class (A+), while also already meeting the future Euro 6 emissions standard.
The E 220 BlueTEC BlueEFFICIENCY Edition doesn’t dissapoint on the performance level though, with an acceleration time to 100 km/h of 8.4 seconds and a top speed of 227 km/h.
