If you’re a motorsport fan, you’ll know Aussie F1 ace Mark Webber has just called time on his Formula 1 career.

After 12 years racing at the highest level, Webber will leave F1 to become a Porsche factory driver at Le Mans.

So with 36-year-old Webber moving onto the next stage of his career, what better time to reflect on his achievements in motorsport’s most prestigious and ruthless category – Formula 1.

From his remarkable fifth place in Melbourne way back in 2002, to his first win in Germany in 2009 and his fierce rivalry with F1 prodigy Sebastian Vettel, flick through the gallery as we pay tribute to one of Australia’s greatest ever racers.

The hardest, fastest and most extreme Pagani Zonda ever has been unveiled overnight.

Called the Zonda Revolucion, the limited-edition model (only five will be made) has been built as a final send off to the legendary Zonda nameplate.

Officially unveiled to selected wealthy clients in Europe, the Revolucion is an evolution of the hardcore, track-focused Zonda R series, with its revised 6.0-litre AMG V12 now producing 597kW/730Nm.

All in a car that weighs just 1070kg.

Power is channelled to the rear wheels via a six-speed sequential ‘box, with the Revolucion also boasting a Drag Reduction System in its rear spoiler – technology sourced from Formula 1.

All of this means the Revolucion should be the fastest Zonda ever – quicker even than the Zonda R which shattered records at the legendary Nurburgring.

So what about price? Pagani is asking 2.2 million Euros, so expect to pay well north of AUD 3 million.

Official renderings of the upcoming Koenigsegg One – the Swedish supercar rumoured to have 1bhp for every kilogram of weight – have leaked online.

Designed for the Chinese market, the new supercar will be developed alongside FFF Automobile, China’s most famous supercar dealer.

Early talk is the limited-edition model will boast a 5.0-litre V8 engine producing around 1043kW.

Expect to see the Keonigsegg One officially unveiled at China’s richest auto show – the 2013 Guangzhou Auto Show.

After months of spy photos and engineering rumours, BMW has officially unveiled its all-new 4 Series.

Essentially a 3 Series coupe in all but name, the new car is longer, wider, lower and 45kg lighter than its 3 Series predecessor.

Wider tracks front (14mm) and rear (22mm) and a 10mm lower ride height help to drop the car’s centre of gravity, with weight distribution, as ever with BMW, sitting at 50:50.

Built on the latest 3 Series platform, the 4 Series boasts bespoke springs and dampers for a sportier suspension tune.

Three engines will be available from launch – all taken from the current 3 Series line-up – with the 3.0-litre six cylinder to be used in the flagship 435i capable of a 0-100km/h sprint of 5.4 seconds.

All engines will be mated to a six speed manual as standard with the option of an eight-speed auto.

The 4 Series will make its official debut at the Frankfurt Motor Show in September before going on sale here in early 2014.

What you can see here is a camouflaged Jaguar F-Type Coupe testing at the Nurburgring recently.

Despite the bad black and white cheque wallpaper, it’s easy to see a shape that’s already quite familiar to us.Wheels drove the roadster version of the F-Type in the July issue, but what these spy images reveal about the Coupe is the treatment done to the rear of the car – such as how that rear hatch will close and the presence of a pop up wing. The roadster F-Type arrives in Australia in August at $202,300 for the V8. The Coupe is expected to land in 2014.

Here’s you first look at Mercedes-Benz’s new Porsche killer – the SLC.

Caught here in heavy camouflage, this SLC is essentially a downsized, cheaper variant of the Mercedes-Benz AMG SLS supercar.

Built to tackle the mighty Porsche 911, the SLC is tipped to feature a smaller turbo-charged sibling of the SLS’s naturally aspirated 6.2-litre V8.

Early power estimates sit at 360kW, with a rumoured Black Series model likely to churn out 435kW.

The SLC is expected to be launched in early 2015.

Mazda’s next-generation 3 has finally materialised, boasting a longer, lower, and wider body, a complete interior overhaul, and the company’s latest SkyActiv chassis and drivetrain technologies.

Due in Australia in early 2014, the BM series small car will adhere to the tried and true formula of its wildly successful predecessors by launching in five-door hatch and four-door sedan guises.

Only the former was rolled out at simultaneous unveilings in Melbourne, New York, London, St Petersburg, and Istanbul this week, although both styles will make it to market at the same time.

The 3 is the third model after last year’s CX-5 SUV and latest 6 midsizer to showcase the Hiroshima company’s much-touted ‘Kodo’ design themes.

Porsche’s new turbo-charged, rear-wheel-drive monster – the 991 GT2 – has been caught testing at the Nurburgring.

Seen here almost entirely without camouflage, the new GT2 is basically the 911 turbo’s insane brother.

Boasting the same 418kW turbo-powered 3.8-litre flat six as the Turbo S (except with even more boost) the GT2 is much more track-focused with early talk suggesting a top speed of 320km/h and a 0-100km/h sprint of 3.0 seconds.

Gone is the Turbo’s four-wheel-drive system, with the GT2 churning its power through the rear wheels only.

Nice.

It’s a film franchise almost as famous for its cars as its earth-defending robots and it looks like Transformers 4 will be no exception.

Early set shots show the new blockbuster will boast more supercars than ever, with director Michael Bay recruiting models from the likes of Bugatti and Lamborghini.

We’re not sure which ones will transform, but flick through the gallery for a sneak peek – including a first look at a redesigned Bumblebee.

It looks more James Bond than real life transport, but for $135,000 you could own the world’s fastest amphibious car.

Called, originally, the WaterCar Panther, this American-made amphibious car can transform from road-going vehicle to speedboat in just 15 seconds.

All you have to do is drive into the water and pull a lever labelled ‘jet drive’ – watch the video at the end of the gallery to see how it’s done.

The Panther, which has its own fibreglass hull filled with closed-cell styrofoam for floatation, then becomes a fully-working boat, capable of hitting speeds of more than 70km/h.

Powered by an outboard motor on the water, the Panther uses a customised 227kW 3.7-litre V6 engine on the road – an engine, the manufacturer says, that allows the car to hit a top speed of 130km/h.
