EVEN MORE GO FOR BIG MERCEDES-BENZ ROADSTER

By EWAN KENNEDY
7 July 2008


Look at it from a distance, and perhaps in slightly dull light, and the latest Mercedes-Benz SL could be mistaken for its great-grandfather – the famed Gullwing Mercedes 300SL of the 1950s. Because the stylists have had a field day with the SL facelift.

Not that the roadster looked bad last week, it’s just that the new model is so much better in its visual stance. Just look at that low front with a big, wide mouth emphasised by a single grille-bar with a three-pointed star in the centre, to see what we mean.

It’s not just the face of the SL that has been changed to achieve this, the bulges on bonnet and big headlights fit nicely into the picture as well. Then there are cues to the most memorable feature of the Gullwing (apart from its upward-opening doors) the big gills on the front guards. This really is a very special car.

There's a lot more to the latest SL-Class roadster than simply its stunning new looks. Under the bonnet changes include more engine power and torque, but this has been achieved without any increase in fuel consumption. Indeed, fuel use and emissions have both been significantly lowered according to official Australian test results.

Even the smallest engine we tested, the 3.5-litre V6, manages to provide 232 kilowatts for strong, safe acceleration and plenty of driving pleasure.

The largest engine is a Mercedes monster, with 12 cylinders two turbochargers and the sort of punch that staggers passengers if they have never ridden in a car like this AMG variant of the biggest Mercedes roadster. Punch that comes by courtesy of a neat 1000 Nm, that’s right, 1000 of Mr. Newton’s finest!

This engine is a modern masterpiece in that it can work at very low revs with never a whimper. You might not consider a car like this for day-to-day shopping, but it will do that mundane task in complete ease. But give it its head on the open road, especially in a straight line, and it simple roars and becomes almost animal like in its characteristics. On a winding road, such as the old road from NSW to Queensland on which we sampled it, it’s something very special.

Sadly, we didn’t get to drive the other hot model in the range, the SL 63 AMG. As before, it features a 6.2-litre V8 engine, now uprated to produce 386 kW and 630 Nm. The most interesting feature is the fitment of a wet-clutch in front of the automatic transmission. This gives sharper gearchanges and even stronger off-the-line performance and is virtually a manual clutch mated to a conventional hydraulic automatic. However, there could be some refinement issues with a setup like this one. We hope to test it soon.

Mercedes’ clever Airscarf system, that blows hot air on demand onto the necks and shoulders of both occupants, was developed for the SL’s smaller brother, the SLK. Now it has been adapted to suit the big SL as well thus extending the season in which you can drive with the top down. Wind up the normal heater, add the warming of the Airscarf and you can enjoy wind in your hair even with the outside temperature down into single figures.

Suspension refinement and increased braking power have been allied with the engine improvements in this latest Merc SL series, resulting in a car that driving purists will just love. As will those more interested in image and prestige than in hard driving adventures.

On the downside, these are large cars with cabin space really only suited to two, and the fuel consumption of the biggest engines is on the anti-social side. It can be argued that these are usually bought as toys, so will spend little time on the road and therefore actual annual consumption won’t be all that high.

The prices of the new Mercedes-Benz SL roadsters aren't for the faint-hearted. Yet the opening tag of $223,000 for the six-cylinder automatic pales into relative insignificance when you look at the mighty rrp of $468,000 carried by the SL 65 AMG.

The full Mercedes-Benz SL-Class range, with prices (excluding on-road costs) is:
SL 350 3.5-litre: $223,000
SL 500 5.5-litre: $306,000
SL 63 AMG 6.2-litre supercharged: $382,000
SL 600 5.5-litre bi-turbo: $385,000
SL 65 AMG 6.0-litre bi-turbo: $468,000
