Mercedes-Benz SL Series 2012 review

Buying artwork is generally an emotional experience. The same logic applies to the Mercedes-Benz SL roadster: there's no rational need to own one, particularly as most SL buyers already have an S-Class or CLS (or both) in the garage. If money isn't an issue, the feel-good factor certainly is and few cars in the three-pointed star's stable make drivers.

Value

In the rarefied strata of SL candidates, six-figure sums don't mean much. It's the perception - their own and others - that matter. The SL350 starts at $225,000; the bi-turbo SL500 is $304,500. Only early adopters will pay those prices - most buyers will spend more to dip into the "designo" catalogue and customise their car.

When the AMG variants arrive later this year, the SL63 will hit showrooms at $381,500; with the V12-powered SL65 at $446,500. You can't sleep in an SL but owners don't need to dream - it's already been realised.

Technology

If you have a fancy, these cars have a feature for it. Take the top off and the electric draft stop, airscarf neck ventilation and heated ensure the enhanced view isn't sullied by wind. And the windscreen wiper sprayers are mounted on the blades and, with the top down, discharge on the downward stroke to ensure the no mist hits the occupants.

The sub-woofers in the Harman Kardon sound system are built into the alloy chassis, literally transforming the car into a boom-box that will drown out any techno-beats from the adjacent lanes. Reach your destination with the top down and a button in the boot - which opens and shuts with a wave of the foot under the rear bumper - lifts the stowed roof to give access to the luggage.

Design

Where the SLS is sculpted for sport the SL's silhouette is all style. This is the marque's longest-running and most treasured nameplate - it's been around for nearly 60 years - and the designers have the unenviable task of creating a contemporary interpretation of a classic design. The proportions are key - long bonnet, humped cockpit and truncated tail.

That said, every successive model has grown in size from the original SL300 Gullwing and the latest roadster is a mid-sized car at 4.6m long. The inside should put a smile on owner’s dials, from the scalloped seats to the standard of the stitchwork on the dash and the choice of three ambient interior colours that are housed in fibre-opted channels around the interior.

Safety

Every acronym in the Mercedes range has been shoehorned into the SL but they should be superfluous, given the car's basic driving dynamics. Recycled aluminium has lifted 110kg from the body's weight - only the A-pillars are steel to improve rollover strength - and the car is noticeably lighter changing direction.

The SL350 comes with six airbags, a drowsiness-detection feature and an active bonnet to protect pedestrians. Step up to the SL500 and there's adaptive cruise control, blind spot and lane-keeping assistance, tyre pressure monitors, “Pre-Safe” software that prepares the car for an imminent collision and a reversing camera.

Driving

The SL takes refined ride to a new dimension. Set the adaptive damping to comfort and there's very little jostling over broken roads. Flick the switch to sport and every crease on the bitumen can be felt through the chassis. Acceleration should be measured in G-force, not seconds - though for the record the SL500 hits 100km/h in 4.6 seconds; the SL350 does it in 5.9 seconds.

The scary part is both cars are more impressive in roll-on urge - and the AMG variants will up the ante again. The only criticism Carsguide can find is the electric steering is precise to the point of being over-engineered: it doesn't give the on-the-edge feedback of genuine sports cars. That'd be the SLS's role, then. In all other aspects, from driver comfort to noise suppression - top up or down - it justifies the expense. And the look-at-me factor is priceless.

Factoid

Mercedes Australia sold around 1000 of the fourth-generation SL and CL models. That figure grew to 2000 for the fifth-generation, which included the SLS.
