2009 Mercedes S 400 Hybrid: Lap of gas luxury

STUTTGART–Why would bother developing a hybrid of its S-class luxury sedan its diesel engines work so in those same cars?

a technical perspective, there is no reason.

The 3.0 L so-called BlueEfficiency has similar performance and gets fuel economy with marginally more carbon emissions than the forthcoming S 400

But from a marketing perspective, Hermsen, in charge of high-voltage management (I#039;m sure it something in the translation) for Mercedes-Benz, the company wants to offer the efficient entry in every He says the S 400 offers better economy than the full from the Far East, which he not to name but clearly can only Lexus, the only other in the luxury class.

Presumably, the angle is also reflected in the that Mercedes-Benz Canada not bring in any diesels in the S-class The company must feel North Americans are not yet ready to oil-burners in the top classes.

So if you want better efficiency and a engine, a hybrid is the only way to go.

The S 400 principle is much closer to used by the Honda Civic than the Lexus LS. A 3.5-litre engine is adapted to run on the Atkinson – radically altered valve reduces emissions and improves substantially, at the cost of low-end

An electric motor inserted the engine and seven-speed automatic (where the flywheel would go) fills in that bottom-end valley, for acceleration very to what the regular S 350 gasoline provides – 0-to-100 km/h in 7.2 versus 7.3 – but with much fuel consumption (7.9 km versus 10.0 in the European cycle – 35.8 m.p.g. vs. m.p.g.) and lower CO2 emissions grams/km versus 234).

This latter measure has not yet much visibility in North but thanks to legislation and consumer it has become a big deal in Europe.

the two power sources generate a of 299 hp and 385 Newton-metres (about 285 lb.-ft.) of

This so-called mild concept generates all or nearly all the of a full hybrid: stop/start at idle, which is by far the most advantage hybrids have in consumption and emissions generation; energy recapture; and whatever advantages this brings of the greenest guy at the country club.

But it so with far less complexity and and carries a much lower penalty – the S 400 is only about 75 kg than a corresponding conventional model – and with no reduction at all in or cargo space.

Part of the credit here to a lithium-ion battery pack – says it is the first in a series car – which is small enough to fit in the compartment where the normal would go. Further credit to the fact that the integrated motor eliminates the need for a starter and alternator.

A two-hour through the Black Forest and west from Stuttgart is enough to draw definitive about the S 400 Hybrid. But initial is that the car feels almost like a normal car, surely is a big part of Mercedes#039;s here.

A Hybrid badge on the lid and another on the centre stack of the are about it for visual clues.

You can up various dashboard displays to how the various systems are functioning.

But if you not to, you might never know. of course, for the fact that the car is much smoother than an add-on starter: no rocking of the engine to get it to spring into

And that at idle, things get quieter inside, as the engine itself off, only to when your right hits the pedal.

Performance is good for a 3.5 L V6 stuffed into a (long wheelbase, in our test case) luxury sedan. I did try an S 500 the 5.4 L conventional V8 back-to-back with the and it is naturally quicker, but not remarkably so.

is aided by the energy recapture of the hybrid module. Indeed, in braking, the wheel discs are not at all –and they come play only during serious retardation.

Some felt this made the feel a bit soft, but neither nor my finely tuned co-driver had any Perhaps our colleagues were for something that just there.

The S 400 Hybrid will be available with the rest of the 2009 range later this Pricing has not been announced.

The S 400 be available in rear-drive only; of the rest of our S-class range with standard four-wheel

Elsewhere, the 2009 S-class receives a mild facelift, a new grille and headlights incorporating LED (Audi didn#039;t enjoy its in this for long).

A new ambient lighting package offers different settings to match mood.

A new Splitview screen the driver to see one display – perhaps the – while the passenger sees else, perhaps a movie on the DVD This is done by some screen technology, based on the you view it from.

There is some doubt North American legislation allow this feature in our

All of Mercedes#039;s nanny system – lane departure warning, assist, drowsiness alert, some of which were on the new E-class – are present and accounted

They are joined by a new Active Control system incorporating compensation, and by a torque vectoring system that generates pressure on the inside rear to counter the effect of the dreaded or pushing, which can be a problem hard braking.

The 2009 intends to retain its lead in the luxury sedan market, and the Hybrid, gain some credentials to boot.
