Default A new breed of high performance electric car - Tango

The Tango is an electric car no wider than a motorcycle, with a passenger or luggage space located tandem-style behind the driver. It is so narrow that four Tangos can fit in a normal-sized parking lot. Despite its precarious looks, it has a very low centre of gravity and will stop faster, accelerate quicker and corner faster than anything else on the road. It may look vulnerable but it has a carbon fibre body shell and a race-approved roll cage structure which make it a very safe, capable and environmentally responsible vehicle.

The Tango is made by Commuter Cars Corporation, which claims it will have a lower cost of ownership per kilometre than most any four wheel conveyance. The narrow profile of the Tango offers motorcycle-like commuter car advantages in terms of parking and performance, without the vulnerability to other road users and the weather and a lack of luggage space

The rear passenger seat can be used as storage space, to carry a baby seat, or it can be removed to carry groceries or other goods. There's a lot more room back there than you'd imagine. During January's Los Angeles Auto Show, the company demonstrated how capacious the Tango's second seat is by putting a 210cm NBA basketballer in the passenger seat, and Commuter Cars Corporation's CEO Rick Woodbury in the front - both were seated comfortably.

Although the Tango could have been built with a fuel cell or internal combustion engine, the company opted for conventional lead-acid batteries which offer a 130 kilometre range (four times the distance the average commuter travels per day) and the dense weight they need located low in the car for stability. With advancements in the price-performance of high-tech batteries not far away, the company expects the range of the vehicle could exceed 300 miles per charge before long.

On top of that, with an off-board 200A charger the Tango can charge to 80% capacity in around 10 minutes on a 200 amp AC service which gives approximately 100 additional kilometres of range per quick-charge. That's not as quick as a stop at the petrol pumps but a lot cheaper, and there is an inevitability that the oil companies will offer these industrial strength outlets through the petrol station chains. A garage roof mounted, solar cell charging
module is being developed so a Tango can be charged for no cost while it is parked. Typically, Commuter Cars Corporation expects one would just plug in each night at home and get a complete charge in less than three hours and be ready for work the next morning.

Possibly a more practical solution to refueling is to use the newly removable battery pack feature. Time trials haven't been done yet, but as it stands you should be able to swap a battery pack in under 10 minutes. With some added automation, Prodrive engineers believe it could be done in less than a minute.

This opens the door to quicker refueling than a typical car. The use of 300-mile range Li-Ion packs will make it actually more convenient than a petrol car once the infrastructure is in place. Meanwhile, for the commuter, the car works perfectly without any need for infrastructure. It's by nature not a family car but it does commuting to work or shopping more conveniently we believe than any car in history.

Okay, that's the responsible citizen justification but just as many people are expected to buy the Tango for its sporting prowess as its eco-friendly benefits. This tiny road-dwelling creature accelerates, handles and stops like a motorcycle but drives like a car.

In a very lightweight body, electric motors can deliver their characteristic torque low in the rev range for amazing low speed acceleration.

With a 9" electric motor driving each rear wheel and over 1,000 ft-lb of combined torque at low rpms, the Tango can accelerate from zero to 150 mph in one gear. It accelerates from zero to 60 mph in four seconds, which makes
it faster than most exotica you can buy off the showroom floor such as the Dodge Viper, Porsche Carrera GT or Ferrari F50 and twice as quick over a short distance as most road inhabitants. It will also stop the clocks at 12 seconds dead for a quarter mile so at all legal road-going speeds, the Tango reigns supreme over all four wheelers though it falls short of the fastest sports motorcycles.

As the Tango is electric, it has some drawbacks, the most obvious being its range but most commuter trips are within the range of an electric Tango and the company is now accepting fully refundable orders for its first three models.

The first available Tango will be the high-performance, luxury Tango 600, which is available now as a mostly-assembled kit requiring less than a day to complete. The Tango is not cheap at US$85,000 so it's not for the less-enthusiastic early adopter but it does come with a luxury kit that places it on paper at least, in luxury car territory.

At that price you get a carbon fibre body, Connolly leather interior, Sparco seats, climate control, a Momo steering wheel, a MoTeC dash and a 400-Watt sound system.

The car will become viable for most of us in its subsequent versions with lesser performance but all-wheel drive via four 50 kilowatt hub motors. The fiberglass-bodied Tango 200 will sell for a far more civilized AUS$40,000 and a subsequent Tango 100 model will sell for US$18,700 and lesser performance again.

Just driver & pillion? Looks like car & motorcycle hybrid.
It is so narrow that four Tangos can fit in a normal-sized parking lot - I'm sure there can be additional 2 motorcycles that can be parked. Concept sounds OK, but I still prefer a motorcycle or a full fledge car besides the exorbidant cost.

yeah you are right and besides the cost I am not able to digest the fact that it reaches 60 MPH in 4 seconds and 120 in 12 seconds.

@sahir thanks for posting more detailed/better quality pictures.

Yeah, that's the power of electric motors & I also heard that the swoosh sound that it makes is good to hear, not sure though. But again, the website says
Quote:
the Tango accelerates from 0-60 mph in under four seconds, finishes the standing 1/4 mile in about 12 seconds at over 100 mph, and can reach over 130 mph with no gear shifting
So it may not be 120, but still its

I wonder what might be its cruising speed. Check this out...
The only people who can afford for this is the rich class; the rich doesn't need this as they've popular Ferrari & Lambos that can clock better than this & they're least bothered about fuel economy or may be even going green.

It cannot be afforded by middle class or poor class due to exhorbidant cost.

So my question - which customer class are they targetting?

Am guessing the customers are those who are either celebrities or those who have money , they probably just buy this and keep it in their garage to show that they are doing their bit for the environment by going green.

135MPH, 0 - 60 in 4secs, MOMO steering wheel, sparco seats, alloy wheels and $85,000 as good as full fledge sports car except for the size.

Good one PRGURU!!!!

You are half right there, prguru. The customers seem to be celebrities for sure, but some of them do take these beauties out on certain occassions. Was going through an article on Yahoo.com and I bumped on this image.

Check out this link for more snaps.
