McLaren has big plans for the Paris Auto Show, and today is teasing its upcoming P12 supercar concept which will be seen for the first time on the show floor in France.

The new car is the spiritual successor to the fabled F1, and might even receive the name P1 in tribute. It will sit above the MP4-12C in terms of price and performance, although both cars will use the same 3.8-liter, twin-turbo V8 powerplant. Horsepower and torque are expected to be boosted in the P12, but where it will really shine is aerodynamics. The car is supposed to tout the “world’s best aerodynamics”, according to Ian Gorsuch, regional director of McLaren for Asia Pacific.

The teaser itself shows a vague silhouette of the car that only gives away the wider front fender flares. If this new concept is anywhere near as extreme as the X1 concept shown at Pebble Beach, it will surely rid the reputation for subdued style that was given to the brand thanks to the MP4-12C.

McLaren has announced it will unveil a new supercar at the 2012 Paris Auto Show taking place later this month, and to whet our appetites has released this sole teaser image. The automaker also states that the next chapter of its brand’s story will be told at the Paris event, which will actually be the first time that McLaren will be presenting at a major international auto show.

Though there’s been no mention of what car is featured in the teaser, it’s widely speculated that it is in fact that highly-anticipated McLaren F1 successor. The silhouette of the new model can clearly be seen and looks very similar to our own preview rendering of the F1 successor, which itself was inspired by actual prototypes spotted testing in Europe.

The car in the teaser also appears to have been inspired by the lines of the current MP4-12C, though there are clear differences between the two.

McLaren’s F1 successor carries the internal code-name “P12” and is billed to be the most capable supercar on the market when it launches next year. Under its skin is expected to be the same MonoCell carbon fiber monocoque found in the MP4-12C, though with modification to accommodate a new Formula 1-inspired hybrid system.

There’s talk of a new V-10 engine appearing in the P12, though previous reports have suggested an uprated version of the MP4-12C’s V-8. Not much is known about the powertrain although it is expected to feature an energy-boost button and total output of around 800 horsepower or more.

The full gamut of McLaren's go-fast chassis technology will also feature, including pushrod suspension, hydraulic anti-roll bars, adaptive dampers and F1-derived traction control. McLaren is also likely to install an updated version of its brake steer technology.

Pricing for the P12 is expected to top the $950,000 mark, making it near enough a million dollars. That's a steep price, to be sure, but with a largely carbon fiber structure combined with McLaren's famous performance and dynamics, it's sure to be one of the most incredible performance cars the world has yet seen. Depending on demand, production numbers are expected to lie somewhere between 300 and 500 units.

Whatever is featured in the teaser, it will be revealed in full on September 27, so we don’t have long to wait now. Stay tuned.

Even as McLaren teases "another big announcement," scheduled just under two hours from now, the company has released a new video, showing off what may well be the next mega-horsepower hypercar to come from the brand.

Billed as the spiritual successor to the famed McLaren F1, the P12--or whatever it's ultimately called--is expected to use a carbon fiber monocoque, equipped with titanium and magnesium hardware for further weight reduction, while getting its power from a hybrid system built around a hot version of the 3.8-liter twin-turbo V-8 also used in the MP4-12C.

We've seen the car in testing in our spy shots, and we've even brought you a rendering of what it might ultimately look like in production form. The video doesn't give us much in the way of details, but through the fleeting glimpses, it does seem to confirm both the spy shots and the rendering in terms of overall shape.

Stay tuned for more shortly.

The teasing is over: McLaren has finally released three real images of its upcoming P1 supercar, which will debut next week at the Paris Motor Show. The car shown here is a “design study” that will be shown in Paris; the production McLaren P1 should debut next year and go on sale about 12 months from now.

As we could infer from earlier teaser photos and teaser videos, the McLaren P1 is styled like an exaggerated version of the company’s current MP4-12C coupe. The rounded nose features a wide and deep lower lip, with big air scoops below each headlight and in the hood. Out back, a giant central exhaust sits above a contorted black diffuser that is likely designed to improve high-speed downforce. The car’s greenhouse is a narrow dome with steeply angled front and rear windshields — don’t expect much interior room for this performance-focused machine. The P1 is certainly much prettier than the weird one-off McLaren X1 that was shown at the Pebble Beach Concours d’Elegance.

Ultimate performance will be the primary goal of the McLaren P1, which is designed as a modern-day version of the company’s record-setting F1. The McLaren F1 debuted in 1992 with a claimed top speed in excess of 240 mph — but the new P1 will be even better.

“Twenty years ago we raised the supercar performance bar with the McLaren F1, and our goal with the P1 is to redefine it again,” company executive chairman Ron Dennis said in a statement. McLaren says the new supercar will be more powerful and more expensive than its current MP4-12C coupe and Spider.

Despite that, McLaren isn’t going for an all-out top-speed record. Managing director Antony Sheriff said in a statement that the P1 would instead aim to be “the quickest and most rewarding series production road car on a circuit.” He also claimed the new McLaren would be the world’s “most exciting and most capable” supercar.

Earlier rumors suggested the new McLaren could have as much as 799 hp, thanks to a 5.0-liter V-8 engine, and a price tag around $650,000. That would help the British automaker position its so-called “Mega Mac” to compete with the likes of the ultra-powerful Bugatti Veyron. Other purported specifications include aluminum pushrod suspension, a carbon-fiber monocoque, active spoilers, and carbon-ceramic brakes.

For reference, McLaren’s existing MP4-12C has a twin-turbocharged 3.8-liter V-8 engine that produces 616 hp and 443 lb-ft of torque. The 2013 MP4-12C coupe costs $241,800 (including delivery charges), while the Spider convertible is $268,250.
