Mercedes Benz Carisson C25 'Super GT'

Mercedes Benz Carisson C25 'Super GT'

Carlsson calls this a ’self-developed’ automobile, but one look and you’ll know it still has a lot of Mercedes-Benz underpinnings. It’s probably a rebodied SL, which Carlsson calls the new Carlsson C25, which will debut at Geneva 2010 this March.

The 6.0 liter twin-turbocharged V12 under the hood of the C25 makes 753 horsepower and an insane 1,150Nm of torque, which will take it from 0 to 100km/h in 3.7 seconds. And 1,150Nm is just the limited figure (likely to preserve the mechanical sanity of drivetrain components) – fully unlocked it has a 1,320Nm peak at 3,750rpm.

Seriously, even in normally aspirated form a 6.0 liter engine would be putting out something close to 600Nm which is already going to give you a huge kick in the butt when you put the pedal to the metal. It’s one of my dreams (and probably any motorheads dreams) to experience acceleration from torque in excess of 1,000Nm one day!

The C25 was designed as a ‘Super GT’. It will go into production, but only 25 units will be made. There’s actually something very interesting about how these 25 units will be distributed. Each owner is promised that he’ll be the only C25 owner in his country! Once you buy a C25 in the USA, no one else can order a C25 and register it in that country. This means it will be offered in a maximum of 25 countries.

Not sure what’s preventing some rich guy from ordering one in some weird country somewhere and importing it to his original country though. Anyone wanna bet if there’ll be one in Malaysia?

Ferrari Formula One F10’s design

Although the regulation changes for this season are a lot less extensive than they were for 2009, Ferrari’s technical team have had their work cut out over the winter months. Charged with not only fine-tuning their engine and chassis to fit the new rules, they have also strived to overcome the performance shortfall that saw the Italian team clinch just one race win last year.

With these twin aims, it’s no wonder that the F10 looks a very different beast to its F60 predecessor. The ban on refuelling has necessitated a wider and longer chassis to accommodate the larger fuel tank, while Ferrari have entirely redesigned the car’s rear - including a new, smaller gearbox - to better exploit the double diffuser, which other teams had championed in 2009.

For designer Nikolas Tombazis, the F10 project has been a long slog, but one that he hopes will eventually prove fruitful.

“For the F10 we had to review the whole project from the nose to the rear wing because of the new rules and also because we had to recover the obvious performance deficit we had last year,” he told Ferrari’s official website, as he explained the car’s main changes.

“Because of the bigger fuel tank we had to deal with a longer and wider chassis. We have worked a lot in the aero department to try to exploit and widen the diffuser, making it more efficient, improving the airflow under the car, and therefore the downforce. We completely reviewed the gearbox and made it smaller so there’s more space for the diffuser and we also worked on the rear suspension. To improve the airflow to the car’s main body and more efficient diffuser, we’ve raised its nose and modified the lower part of the chassis. The front wing has also been improved.”

2010’s ban on refuelling - as well as the grid-wide agreement to stop using KERS - has also imposed new demands on the Ferrari engine. And while the freeze on development, in place since 2006, restricts their freedom to make changes, engine department boss Luca Marmorini is pleased with the revisions they have made, especially in terms of reducing the engine’s fuel consumption.

“Naturally we tried to improve performance but this only led to limited advantages because the engine development is frozen,” he explained. “From a technical point of view, reducing consumption was one of the most interesting things this year. We worked to find new and unusual fields of application for the engine, and we obtained some really interesting results.

“Consumption equals performance. Consuming less fuel means less petrol on board, and so whoever consumes less fuel will be faster on the track. Naturally, constructing an engine that consumes less brings about higher risks in terms of reliability. We worked very hard over the winter with our simulations and we are confident that at the start of the year we should be reliable.”

Weather permitting, the F10 will get its first shakedown run at Ferrari’s Fiorano circuit in Italy on Friday, before it’s transported to Spain for next week’s multi-team test at Valencia, which begins on Monday. - Ferrari News
