McLaren & Mercedes Last Collaboration: Limited Edition Topless Carbon Plastic Bodied SLR

Before going separate ways, Mercedes-Benz and McLaren have decided to produce one final edition of the SLR. it's super fast, lightweight and painted as ugly as possible.



According to reports from the German car magazine, Auto Motor und Sport (who captured first shots of this car under testing), this special SLR will come with neither roof nor windscreen, as a result of weight-shaving measures to trim its curb weight by about 200 kg (or about 440 pounds).

"The concluding SLR will feature an open-air only construction. Gone is the roof; gone is the windscreen - a small wind deflector will be the singular element between the SLR's occupants and the great outdoors. To reduce weight, a carbon plastic body will be used, while air conditioning and power windows will both be abandoned as well. The result in a weight savings of some 200 kilograms, enough to help the model reach 186 mph from a standstill in 26 seconds and achieve a top speed of 217.5 mph."



This means that only a small wind deflector stands between the driver and the ferocity of the wind, as the speedster tosses the countryside behind in a possible breakneck top speed of 350 km/h (or 217 mph). That's about 8 mph more than the latest SLR 722 Edition.

The model is said to have been inspired by Rudolf Uhlenhaut’s legendary 300 SL in 1955, and earned the famous moniker Silver Arrow.:

Only 75 of these lightweight cars will be produced.

Hamilton Wins The Monaco Grand Prix, Was It The Diamond Helmet?

First of all, the race is over and 23 year old Brit Hamilton Lewis has won. And Finnish born Heikki Kovalainen, who had to start last after stalling before the formation lap, was fourth on the grid, so it obviously wasn't the diamond helmet. What diamond helmet, you may ask?

In the build up to the 2008 Monaco Grand Prix, Vodafone McLaren Mercedes and Steinmetz, creators of the world's finest diamonds, announced the continuation of their long-running partnership by adorning their drivers with custom diamond helmets.

This year Steinmetz worked closely with the Vodafone McLaren Mercedes drivers, Lewis Hamilton and Heikki Kovalainen, in creating their own personalized race helmets, which both drivers used throughout this past Monaco Grand Prix weekend.


Above: As if being a race car driver isn't sexy and exciting enough, Lewis and Kovalainen were given their own custom helmets adorned with diamonds.

Each helmet has the signature of the driver pavéd with a line of hundreds of Steinmetz's handcrafted diamonds.

A bit about McLaren and the Monaco Grand Prix:

The Principality of Monaco is the heady and glamorous location for round six of the 2008 Formula 1 World Championship. The 20 cars and drivers will compete around the 3.34km street circuit, racing between the Princes's Palace and the Mediterranean sea covered in some of the World's most lavish yachts.

Since the start of the McLaren and Mercedes-Benz era, the team has won the race on five occasions. Mika Hakkinen in 1998, David Coulthard in 2000 and 2002, Kimi Raikkonen took the spoils in 2005 with Fernando Alonso claiming victory just ahead of then team-mate Lewis last year.

The connection to the race stretches back to the 60s, with Bruce McLaren taking the M2B to the track to make the marque's Formula 1 debut. In that time, the team has won a record 14 out of the 65 of Grands Prix staged in the Principality. This began with Alain Prost in 1984, kicking off a winning streak that stretched until 1993, with the exception of 1987. Five of these were at the hands of Ayrton Senna.
