Classy Mercedes S turns up a hybrid

In response to market demands and also to sharpen its image, Mercedes has just unveiled a hybrid version of its S-Class – the S400 Hybrid.

Although diesel engines (and Mercedes knows something about the subject) have become increasingly cleaner, more silent, smell-free and more comfortable to drive at low speeds, the buying public is still more drawn to the word “hybrid” …

For the past few years, Mercedes-Benz had been carting around a few hybrid-engine prototypes at auto shows, so it should come as little surprise that it now launches its first production hybrid system in one of its current offerings - and its most prestigious model, no less.

The S400 Hybrid gets the 3.5 litre V6 from the S350, a model unavailable in North America. Mercedes tagged on a permanent-magnet electric motor to add 20 horsepower and 118 lb.-ft. of torque. Although the engine stops as soon as the car is immobilised and the energy from braking is recaptured (characteristics of all hybrids), it is impossible to drive solely in electric mode.

Of interest, though, is that the S400 Hybrid is the first mass-production vehicle to use lithium-ion batteries. More compact, thus lighter, than those to which we have grown accustomed (nickel/metal hydride), they’re located under the hood. The traditional battery is in the trunk.

It is practically impossible to tell you are driving a hybrid automobile, aside from the little “Blue Hybrid” badges. Power at low speeds is rather weak but, thankfully, the seven speed automatic transmission works marvellously well and gear changes are smooth as a silk. At 100 km/h, the engine rests as the odo reads 1,700 rpm (you have to get up to 120 km/h to reach 2,000). Mercedes claims fuel consumption in the neighbourhood of 11.0 litres per 100 km, although a more energetic drive will have a less positive eco-friendly effect.

The actual driving is a little too disconnected for my liking, but handling is very sophisticated even with a weight of 2,000 kg. The on the road noise level is impressive, something that can also be said about seating comfort. And that is without a doubt something the typical S-Class owner looks for.

As for the car itself, we must underline the fact that this is an S-Class, Mercedes’ most prestigious automobile. The interior space is quite impressive, the level of equipment is practically indecent and comfort is maintained no matter what state the road is in. Even with the enormous amount of accessories, Mercedes has managed not to create an overwhelming dash. A central button on the console allows the selection of a bunch of parameters (navigation, heating, telephone, audio) and its usage is not too complicated. As for safety, there are so many passive and active systems that occupants have a better chance of being struck by a plane while watching TV than being hurt in this car IF it crashes.

Prices have yet to be set, but you can bet they will be out of range for most people. The 2009 entry to the line, the S450 4matic, sells for $108,000.
