On the face of it, a hybrid S-Class exist. If anyone wants a luxury car, they buy a fractionally smaller (but pretty ritzy in the overall of things) luxury car like an Or an S-Class diesel. Actually, if the world were really the the vast expense of developing a car the S-Class hybrid would be better spent building electricity generators, or just in the town square in Stuttgart and out free loft insulation.

But is obliged to be part of the hybrid For a start, American luxury-car don’t think diesel is a fuel for anything smaller a Peterbilt, whereas the mere of a hybrid in the range — a vast and thirsty one — is by your average American as to turn the world’s deserts lush meadows overnight.

Never mind, this Mercedes, the engineers have the hybrid issue with diligence. The company is developing two separate hybrid systems. The is this one, a comparatively system that sticks a electric motor in the place the V6 engine’s flywheel would be. has another system in the works for its SUVs — a full-hybrid entirely replaces the conventional set-up.

The cost of developing stuff means it makes only if the effort is shared. So the mild hybrid system also show up on a BMW 7-Series. By the token, the full-hybrid system is the as on some of GM’s SUVs in the and on the forthcoming BMW X6 hybrid.

Despite, or because of, the complex technology the driving experience is utterly. I drove a prototype, by the way. The thing will be introduced in the US this spring, along a mild range-wide face-lift. calls it the S400 BlueHybrid, though the engine is a 3.5-litre. play, because it feels a bit muscular than the S350, to the extra torque that from the electric assistance, at low revs.

So you’ve got a car that wafts with the sort of stately a V6 petrol S-Class normally As with an S350, there’s urge (slightly more in case) that in normal or even at a good clip on it never seems to be trying hard. And then you commit to a bigger line of trucks usual, or make a spirited on a series of uphill bends, and reminded thatan S-Class is a hefty lumpof metal and suddenly,the V6 starts to run out of answers and pretty strained.

At full-throttle kickdown, the electric doesn’t actually help it’s optimised to complement the V6, not it. So where a petrol engine is — under about — the electric motor is But at higher revs, the electric fades. In numbers,it looks this: the motor makes ft of torque at zero revs, but its torque falls with it contributes only 20bhp to the by the time the petrol engine is in its Still, all that low-down does make the car feel in traffic, the auto ‘box fewer shifts when travelling at suburban speeds.

The V6 out as you cruise down to rest, you in calm silence until you off the brake, ready to move At which point, the engine back to life. Any anxiety sitting there engine-less melts, because the restart is by the big electric motor, rather a normal starter motor, so much smoother and more

In the normal run of play, the battery its charge for free, from braking rather than the That simplifies things in with a full hybrid. But be fooled into thinking is a simple engineering job — not.

For a start, the engine is modified so as to be efficient in mid-revs, as the electric motor runs out of The power electronics monitor so that if the battery is well-charged it back the engine and calls on effort from the motor, if the battery is low, then it the electric motor and opens the taps wider. You never the difference.

The brakes are on a special linkage. When the battery is low on the first section of pedal is given over to regenerative and it’s only if you push on the pedal that the wheel are called up. But at full charge, the alters so that you get friction as soon as you brush the pedal. canny, and as with the rest of the you don’t actually feel complicated bit of technology in operation. The just feels like on a normal S-Class.

The battery in question is a lithium ion one of the first of the kindin a production It’s under the bonnet, so no in cabin- or boot-space is called In all, the car gains just over a regular S350.

line, then: fuel Significant, actually, at some 21 per in the European test cycle, with the regular V6 S350. But we be getting it in the UK, because the diesel is that efficient already.

the beauty of this mechanically (if electrically complex) hybrid is that it can be scaled for other models, and even diesels. And there is another reason to do One thing about the future of the car is much certain: electricity is to be involved in one way or another — at hybrids, fuel cells and cars.

The more a company knows electricity storage and control, the it will be. And as the S-Class reveals, knows a lot.
