Recently dual-speed supercharger is advocated by a UK-based Antonov Automotive Technologies company. The dual-speed supercharger is helping for the current trend of downsizing displacement and force inducting engines in efforts to improve fuel economy and emissions.

“Car makers are increasingly looking at superchargers to enhance the performance of small engines. Unlike turbochargers there are no heat issues to manage, and the study of exhaust gases can then be assigned to energy recovery systems,” says Antonov operations director Chris Baylis.

According to Antonov, at alower engine RPMs, the dual-speed supercharger which can run faster at low engine RPMs for that instant “kick”. While at high engine RPMs it will run slower at high engine RPMs to extend the boosted torque curve across the rev range. This is cheaper when comparing to the complex combinations of a supercharger and turbocharger like the Volkswagen 1.4 liter TSI’s twin-charger.

Recently there are some spy shots of the Ferrari 149 GT California around the net. Ferrari had reveilled a few more details about the entry-level Fezza. Unlike some spy pics we've seen that obscure everything from the B-pillar back, these newest images show a steeply raked rear windscreen that terminates into an artificially elongated trunk, rumored to house a folding hard top. The front clip is sporting a large radiator intake and the hood stretches back in true Ferrari style. Project F149 is rumored to be powered by a 4.7-liter V8 producing 480 to 500 hp.

Recently Lamborghini will launch a new designed Lamborghini. However this time a Lamborghini that will stay a little longer unborn due to a lack of of orders, only 3. The design is done by Italian coachbuilder Magvisio and is impressive. The project is called “Ferruccio” and is a rebodied Murcielago LP640 that would have been faster than any current car wearing the Lamborghini badge, with a claimed top speed of 230mph (368 kmh).

The Tesla Roadster is and powerful roadster. It runs on exhaust-free plug power, and it's already primed for more power. A specialty car importer is quoting the Euro Tesla's power at or over 300 hp, with a 13,000 rpm red line and a single speed transmission.

The revised gearbox drops a gear, adds an upgraded power electronics module, and provides better cooling. It seems the hype machine that is the Tesla Roadster is beginning to heat up, and more power will only make us want the green little drop-top more.

This maybe the BMW M1 prototype. It shows a sleek two-door, probably mid-engined coupe with attributes of the new M3 incorporated into its design, especially the front fenders and hood. With BMW introducing the M1 Hommage Concept at the Concorso d'Eleganza at Villa d'Este last week. However, we hope that this is not a photoshopped image.

Recently, Bugatti had released another limited edition of the Bugatti supercar dubbed the Bugatti Veyron Sang Noir even though it has just presented its latest limited edition, the Bugatti Veyron Fbg par Hermès, at the 2008 Geneva Motor Show last month.

The Sang Noir (means ‘Black Blood’) is dedicated to the classic original Bugatti Atlantique 57S from the 1930s featuring carbon fiber panels and all-black interior.

The Bugatti Veyron Sang Noir includes blacked out headlights, aluminum side mirrors, aluminum grille surround, black powder-coated alloy wheels and leather and Alcantara trim on the interior.

Mercedes-Benz, AMG and HWA are planning to release new models in the coming years. This included a high performance coupe which said to replace the SLR and to compete SL Black Series from AMG. Almost nothing is known on this car except then it will have a long nose and a lot of power. MotorAuthority claims it’ll be called the SLC and that it will runn on the same 6.2 liter V8 that sits in the Black Series SL. The output will be around 670 bhp.

Another key feature of the car will be a pair of gullwing doors, which is a throwback to the 1950’s 300 SL.
