The Vodafone McLaren Mercedes F1 team combines the strong driver pairing of Jenson Button and Lewis Hamilton for the third year running in 2012, along with a substantially revised car to meet the FIA's rule changes. The most noticeable change between last year and the new MP4-27 is at the rear, where tighter rear carbon-fiber composite body shaping has been designed to meet the new-for-2012 exhaust rules, whilst smoothing airflow to and from the coolant and oil radiators.

"We reverted to a more conventional side-pod shape for this season because the U-shape was less suited to the new exhaust geometry restrictions," Director of Engineering Tim Goss explains.

"For 2012, the exhaust tailpipes now have to exit along the U-channel - so that particular feature was no longer really viable due to the new geometry restrictions. As a result, we decided to adopt a different approach to the way we feed the rear of the car.

"The regulations around the exhausts are very prescriptive: the exhausts must now exit within a very tight space at the rear of the car in order to minimize their aerodynamic influence. The final 100mm of the exhausts must be cylindrical - so they can no longer be oval, or flattened - and must be sited at a particular vertical and horizontal angle - between 10 and 30 degrees upwards. That's to direct the exhaust exit away from the floor."

Powerplant

Throughout the car, every component was scrutinized with a view to reducing weight, increasing life and improving performance, but the basic and well proven Mercedes 90 degree 2.4 liter, 32 valve V-8 remains.

"With the regulations remaining relatively stable, we've really been able to focus on the detail with this year's car," says Jenson Button. "I still think we had a very fast package last year - it was very strong in certain areas - and our race pace was almost always fantastic, but we're hoping for a further step forwards in 2012. With Mercedes-Benz, I think we also had the best overall engine and KERS Hybrid package in the pitlane."

Team Green

As a sign of the times, Vodafone McLaren Mercedes became the first carbon-neutral Formula 1 team last year, reducing its carbon footprint and purchasing carbon credits to completely offset the team's emissions during the 2011 season.

This McLaren is really going to fly if it is only 95 kgs !!!

Cleary the car weighs more than 95kg, otherwise I could bench press it all day long lol

In their infinite wisdom, the FIA has managed to establish parameters which make F1 uglier than ever.

Phaugh!

I dont look at F1 cars as Ugly or not. They are designed to be the best at cutting through the air, OR to cause extra drag, so they are function before form, which I totally understand.

Although personally I always find the racing Cars very beautiful as Im looking at the designs from an engineering viewpoint.

I'd just like to say well done in making the sport a bit more exciting than it was previously when they were in a nose to tail line for most races with very little overtaking ability due to turbulent air when they approached each other making it impossible.
