Hydrogen has been touted as a viable fuel source for decades, and seemingly every day, some new or upcoming hydrogen-powered milestone is reached or discussed. However, in nearly every case, hydrogen is being touted as a standalone fuel source. But what about using pure hydrogen mixed with gasoline to increase fuel economy and reduce emissions?
Ronn Motors, of Texas, has built a car it claims will do does just that. Called the Scorpion, the engine is a 3.5-liter, six-cylinder VTEC from Acura, equipped with two turbos and an intercooler to take it from 280 hp to 450 hp. The turbo'd six is connected to an on-demand hydrogen system that breaks down water molecules and holds them in a non-pressurized tank which doesn't necessitate the need for a hydrogen refueling station. The hydrogen is drawn through the intake manifold and between 30 and 40 percent hydrogen is mixed with the gasoline. As less gas is used, Ronn Motors says the Scorpion can do 40 mpg.
DuPont Registry just named the Scorpion a Publisher's Choice as "one of America's first premium eco-exotics." True, the Tesla might be more eco, but to our eyes the Scorpion (rendering) has got the exotic thing properly nailed. But when can you get one? According to Ronn, the car will be out this fall. And when you want to get it off the lot, the 2,100-pound Scorpion will supposedly take you to 60 in no more than 3.5 seconds. Ronn will probably even throw in a full tank of gas... and water. You'll need to provide the take-home money: $150,000.

Shelby Supercars has just issued its second release this week about its miraculous new project, the Ultimate Aero EV. As we read the announcement, it was obvious that it was exactly the same release from just a few days ago and the hyperbole was in no way toned down. They are promising to deliver a working prototype by February of next year, followed by full production examples by the fourth quarter of 2009. That, in and of itself, is highly improbable, but it just gets better from there. The performance the company is promising is insanely impressive and about as likely to come to fruition as airborne swine or your fairy godmother.
SSC promises two, 500hp electric motors equipped with a triple disc clutch and a six-speed gearbox. As Tesla found out the hard way, making a gearbox last with an electric motor is tough, even with half as much power. But it gets better. SSC promises a power source with extended times between charges, perhaps as long as several years. We're still confused, but we don't think it's a coincidence that the company is making this announcement in the same week it announced its hopes of securing new venture funding.
Building a car powered by an internal combustion engine to go 250 mph is less of a big deal in this day and age. You just need an engine with enough power and a slippery shape. Building the kind of electric car that SSC is promising involves invalidating the most fundamental laws of physics. So for the time being, we remain comfortable skeptical.




It's hard not to follow a story like the veritable fleet of new supercars set to follow the controversial Mercedes-Benz SLR McLaren. The supercar came out of the partnership between Benz and McLaren in Formula One, but while the racing cars have been highly competitive, the SLR has been less so. As a result, Mercedes and McLaren are going their own separate ways for the next generation of high-performance exotica.
Mercedes, with in-house rodders AMG and its racing spin-off, HWA, is preparing two new models to succeed the SLR: the SL65 AMG Black Series (which has been spied many times over) and the SLC (which we've seen disguised in Dodge Viper bodywork). McLaren, meanwhile, is anticipated to produce the new P11 mid-engined supercar on its own, without Mercedes input. The dissolution of the car-producing enterprise between the two powerhouses is not expected to affect their joint grand prix racing program.
The last iteration of the SLR – following the original coupe, the Roadster and the 722 – will be a limited-production lightweight speedster, on which we recently reported. Despite all its available variants, Mercedes has sold fewer than 1600 examples of the SLR to date.

The word "cinque," as in Pagani Cinque, means "five." The newest Pagani is the road-legal version of the racetrack-only Pagani Zonda R, and there will sadly be but five of them made for which all are already spoken. Not that we would have bought one, but it would have been nice to have had the opportunity.
The Cinque, with 678 horsepower and 575 lb. ft. of torque will teleport from 0-to-60 in 3.4 seconds, and at 186 MPH the car creates more than half its own weight in downforce. It also gets a sequential 6-speed transmission, and you can flick through the gears with paddles or a gear shift on the center console. That console and the racing buckets that face it will probably be made entirely of carbon fiber.
Pagani has created a bespoke titanium and carbon fiber material that means the Cinque weighs 40 pounds less than the Zonda F. Weight savings are also achieved with titanium monobloc wheels, as well as the magnesium and titanium Ohlins suspension. It is the very definition of a supercar: fast, light, rare, hot. Be sure to check out the new gallery of hi-res photos of the Pagani Cinque below, because that's probably as close as you'll ever get to one.


Though Saleen won't be officially unveiling its new supercar, the S5S Raptor, on stage until tomorrow, we've got pics and details for you now. Though slated to slot below the hardcore S7 in Saleen's lineup, the S5S Raptor looks no less the part of a high-powered high-performance sports car. It's powered by a supercharged 5.0L engine mounted amidships producing around 650 horsepower and 630 lb-ft. of churn on a steady diet of E85 ethanol.
Developed as a collaboration between Saleen and specialty builder ASC -- both of which are owned by the same private equity firm -- the car is plenty of tech and a bit of throwback. The aluminum chassis 2-seater can get from 0-60 in a supercar-standard 3.2 seconds. When it's time to stop, six-pot calipers hidden by 20-inch wheels clamp down on 15-inch rotors up front. The retro bit: a six-speed manual gearbox. A paddle-shifting sequential is also in the works and may be ready when the car goes into production in 2010. Compared to the S7, the S5S is another relative domestic bargain at only $185,000.
