The Velozzi

Unlike the rest of the cars on this list, this car is a hybrid rather than a full electric vehicle. The car is being created by Team Velozzi to compete in the 2009 automotive X-Prize, a competition to find a super fuel-efficient vehicle that is environmentally friendly, desirable, and marketable. The Velozzi is certainly all those, at least for me. The car boasts a top speed of 200 mph and goes 0-60 in under three seconds. It gets better. The hybrid’s gas tanks can be fuelled with almost anything, including gas, biodiesel, methanol, or pretty much any of your normal alternative fuels. The design is top notch as well. The Velozzi is an Italian car, and its designers took some of their design from the classic Italian sports cars. If you look closely, you can see a bit of Lamborghini in it.

MDI develops 'The Air Car'

While automakers from all around the globe are trying to fancy what can be a truly fuel less car, MDI has introduced a car that runs on air.
No I am not kidding with you but according to the developers the car is completely pollution free and runs on compressed air. The pressure inside the tank is a staggering 300 bar.
A single tank of compressed air will be enough to run the car for 4500 kilometers and the car has a top speed of 110 Kmph that’s not bad if you consider that all you need for fuel is nothing but air...!

MIT Media Lab foresees stackable, foldable 'City Car'

A team of researchers at the MIT’s media lab are busy developing a prototype of lightweight stackable electric cars that could help overcome the congestion problem. The prototype vehicle dubbed the City Car could be folded and stacked at central sites.
The City Car will be powered by a robotic drive system transformed from the lowly wheel. Each wheel will integrate an electric motor, steering and braking machinery, suspension, and digital controls. All these would be merged into sealed entities that could be snapped on and off.
The City Car will start at the mere press of a button and will boast a handlebar instead of a steering wheel. Lightweight material like Kevlar or carbon fiber will make the body of the car. The notion of the City Car was devised as part of a strategy for plummeting carbon emissions

Tesla Roadster: Red and Green

One look at this baby and I am sold! Red never looked hotter and greener!
The Tesla Roadster is an all sleek, all American, 100% electric car that does 0 to 60 mph in less than 6 sec! Needless to say, it has won every award since its debut including the cleanest startup award for 2007 from TechCrunch !
The Torque curves of Roadster are, of course, stellar. They are promising peak torque even at 0 RPM! So, no auto gear changes and high energy efficiency even for the highest acceleration possible !! Apparently, it is alarmingly quiet for the kind of acceleration and power it provides ! That is amazing!!
You know what else is cool ? Its carbon foot print ! It is all electric so you only need to look got your state board’s carbon chart to worry about . I found out from his blog that the CEO of Tesla powers his home off of a solar panel grid !
The looks are a killer and the price is north of 100G but, given its startup mode, it has been sold out every year so far!! That truly speaks for how cool this car is !
A 5000 USD refundable deposit starts the process and locks in price. An additional 50 grand would lock in your delivery date as well.

Audi TT 2007

Apparently, Audi just couldn't wait. The German automaker was all set to lift the veil on its next-generation TT at the New York International Auto Show, next week. But Audi decided not to wait for the New York show, a lightly attended event for the European press, and unveiled the car in Berlin on Thursday.It's been six years since Audi introduced the original TT, a car that did a lot to buff up the automaker's sporty image. For the new version Audi increased both the car's overall length and width. It now measures 165 inches nose to tail, and 72.4 inches door to door, up five and three inches respectively.The 2007 TT gets a sharp sheetmetal makeover, which removes the Deco lines and replaces them with bolder forms that hint at the Nissan 350Z, which was itself inspired by the original TT, according to its designer Ajay Panchal.For the new TT, Audi combined aluminum and steel for a new body structure. Audi claims optimal weight distribution, but also adds a pop-up rear spoiler that deploys above 75 mph.Audi will offer the next-generation TT with two engines: a turbocharged, direct-injected 2.0-liter four-cylinder gasoline engine that delivers 200 hp. This model accelerates from 0-60 mph in 6.4 seconds, Audi says, and reaches a top speed of 149 mph. The other powertrain is a 250-hp 3.2-liter V-6 that sprints to 60 mph in 5.5 seconds and has a limited top speed of 155 mph. Both engines are mated to a six-speed stick shift or can be combined with an S-tronic (sequential manual) transmission using Audi's slick double-clutch system. The 2.0-liter TT has front-wheel drive; the V-6 is a quattro.A new rear suspension and other improvements, combined with a wider thread and larger wheels, are aimed at improving handling. Later in the year, Audi will add an adaptive suspension system.The new TT will be equipped with automatic climate control and an upgraded audio system. Adaptive lighting/corner lighting and a reverse-parking system is optional.The new TT Coupe will be available at the end of summer and will be joined by a Roadster in 2007.

Audi Avus Quattro

The Audi Avus Quattro was a supercar-styled concept car from the German car manufacturer, Audi. It was first introduced at the 1991 Tokyo Motor Show. The Avus Quattro had an aluminum exterior, which made it a lightweight, sleek and safer automobile. The Avus Quattro’s engine was supposed to be a 6.0 L 60-valve 12-cylinder engine producing 509 hp (380 kW), capable of accelerating the car from 0 to 60 mph (97 km/h) in about 3 seconds and a top speed of 211 mph (340 km/h). The exact car shown at the Tokyo Motor Show, however, had a dummy made of carefully painted wood and plastic for an engine because at the time, such a powertrain was still in development; Audi-made W12 engines were not available to buyers until Audi presented its flagship A8 a few years later.

Mercedes SLK

The SLK got even better with thanks to new styling which takes cues from the bigger SL and the McLaren SLR. Stunning looks, Mercedes build quality and that metal folding hard top guarantee success for the little Merc, despite growing competition from cheaper convertible coupes, and the increasing performance of cars like the Porsche Boxster.
