The Mercedes-Benz E300 BlueTec has been officially unveiled at the Detroit show next month
9 January 2012

Mercedes is set to join the ranks of manufacturers selling hybrid-powered executive cars with this diesel-electric Mercedes E-class, which has been officially unveiled at the Detroit motor show. The E300 BlueTec, due on sale next September in both saloon and estate bodystyles, is engineered around the most powerful version of Mercedes’ 2.1-litre four-cylinder turbodiesel engine.

The headline CO2 figure of 109g/km will make the E300 BlueTec popular with company car users. It undercuts BMW’s petrol-powered Active5 Hybrid by a significant 40g/km.

The 201bhp/369lb ft diesel engine is mated to a 27bhp/184lb ft brushless electric motor sited within the gearbox housing. A 0.8kWh lithium ion battery is said to provide an all-electric range of less than a mile at speeds below 35mph. Together, they are claimed to provide the E300 with a 0-62mph time of 7.5sec and a top speed of 150mph. With a host of fuel saving measures, including stop-start, brake energy recuperation, a sailing mode and low rolling resistance tyres, it is claimed to return a combined 67.3mpg — an improvement of 9.6mpg on the existing E250 CDI saloon.

The US-only E400 Hybrid uses a 3.5-litre V6 petrol engine mated to the same electric motor used in the E300. This delivers 32.4mpg on the US fuel cycle, which is regarded as beingtougher than the European cycle.

Hybrid versions of Mercedes saloon car range are likely to be restricted to the C, E and S-class for cost reasons, according to its head of research and development Thomas Weber. "An efficient four-cylinder engine is a more cost-effective way of achieving low emissions in small cars," he said. Weber also confirmed the next S-class, due later this year, will be offered as Mercedes' first plug-in hybrid model.

Mercedes-Benz E-Class
The E-class more than lives up to traditional Mercedes values

I guess how cars like this will sell depends on your tax situation and what price it sells for compared with the gain in fuel economy. It will be interesting to see the sales performance between electric/prius hybrid/Volt/Volvo,Peugeot 4X4 hybrid and these micro hybrid Mercedes. It all adds to more choice and interest for motorists.

Yes it's a tax system special. I'd like to see a back 2 back economy test with a regular E250 in real world conditions. I'm wondering where motor industry can go with tailoring of power trains for the economy tests. We already see electric motors that's assistance flatters results. On the engine side I just had an idea - a dual crank V6/V4s that run as V2/3 when the engine management detects driving akin to the economy tests ?

If you're going to have a car like this then surely having a further EV range is desirable, like the V60 Hybrid.

Is that all?

Seems like an elaborate, and no doubt expensive, way to make small fuel economy and CO2 savings when the regular cars aren't that far away. Shame, I really like the E250 CDI but this seems a little pointless.

Yaaaaaaaaaaaaaaaaaawwwwwwwnnnnnnnnnnnnnn........

Anyway, 67mpg and 109g/km for a large executive saloon that can do 0-60mph in 7.5 seconds is pretty impressive. This car would probably be great as one of those posh chauffeur driven taxis, as it would offer great capability and economy on both the motorway and in the urban environment.

I'd take mine as an estate. Seven seats would come in handy!

The all electric range isnt very far, especially when compared to Volvos new V60( sorry if its not the V60) but for a big exec saloon 109gco2/km is pretty dam good! ha at least you would get more respect from your friends than if you were driving this than a prius haha

Very true! I don't mind hybrids, but I'm not a fan of electric cars. They are far too flawed for everyday use due to poor performance, low range, long recharging time, price and reliability issues. This diesel hybrid makes perfect sense, as you just put diesel in it like you would a normal car, but even with over 200bhp and nearly two tonnes to pull along, you can get 67mpg out of it.

In estate form, this would be my favourite hybrid. Even better than the original Insight (which in my opinion was a revolutionary vehicle, and will be a future classic).

Surely the purpose of this car is to provide a more fuel efficient model in North America where diesels don't sell as well?
