Roadster Sport debuts, merges performance with green-tech

Tesla Motors made news late last year when a number of its Michigan employees discovered they were to be laid off through a posting on a business site in which company representatives discussed the closing of their plant and release of its employees.  While the end of the year brought bad news, 2008 was still a good year in Tesla for some respects as it saw production of its Roadster vehicle begin in March.

A leaner, more consolidated Tesla Motors greeted the press at the North American International Auto Show this week.  The company had big news, announcing a new vehicle, the Tesla Roadster Sport.

The Roadster Sport melds the environmental performance of an all-electric, zero on-car emissions vehicle with the on-road performance of a high-end sports car, and achieves impressive results.  The Roadster Sport can accelerate from 0 to 60 mph in a mere 3.7 seconds, two tenths of a second faster than the standard Roadster.

In order to speed up the Sport, Tesla created a hand-wound stator and increased winding density for lower resistance and higher peak torque.  The stator is the stationary coil in an electric motor in which the rotor, attached to the drive shaft spins.  The Roadster Sport also adds Yokohama’s Ultra High Performance tires, and an improved tunable suspension with adjustable dampers and anti-roll bars. 

In the U.S. the Roadster Sport will have a base model price of $128,500, and it will also sell in Europe where it will retail for €112,000 (excluding VAT). 

Michael van der Sande, Tesla’s senior vice president of global sales, service and marketing touted the Roadster Sports performance, stating, "This car can beat nearly anything in its price class – yet it is twice as efficient as compact hybrid sedans.  If you refuse to compromise on performance or the environment, the Roadster Sport is your only option."

CEO, Chairman and Product Architect Elon Musk lauds, "The Roadster Sport embodies Tesla’s spirit of continuous improvement.  The Roadster has been a great success, but no one at this company remains satisfied with the status quo."

The Roadster Sport uses Tesla Motors' patented powertrain.  It seats two passengers and production is planned to begin in 2011.

Tesla Motors says that it has shipped 150 Roadsters, thus far, and that 1,100 people are still on a waiting list.  However, the wait may be a fortunate one, as waiting customers now have the option of upgrading to a Roadster Sport.

The Roadster and Roadster Sport will go head to head next year with GM's Chevy Volt, which will debut at a much lower price point (around $40,000 before tax credit).

With a turbocharger you have potentially higher peak horsepower.
Depends on the size and design of the turbo's. There's no hard fast rule on where they make power. Most OEM turbo's are small and spool quickly making their power in lower rpm ranges. The turbo in my car (OEM) makes max power as low as 1700 rpm and putters out at 5000 rpm (4 cyl). It just depends on what the manufacturer and the target consumer wants/expects.

Anymore with current turbo designs, the lag is unnoticeable. Short of the completely decked out race designs that are made to make power up top through cam tuning anyway, turbos are quite quick to make power and do so very efficiently.

Then it is tuned wrong or you misunderstand the specs, A turbo 4 banger usually redlines at 7k-9k and naturally makes peak hp around 1000-500rpm short of redline. If it really peters out at 5k then you are missing out on a lot. And all in at 1700rpm is ludacriss unless it is really, "way" too small. maybe the boost is coming in at 1700rom? Then again OEM, is like a government Uniform: You can have any suit you want as long as its plain black; you can have any power level you want as long as its weak. They are much better than 20 years ago, I drove a 1989 Dodge Daytona Turbo Z Whatever and it has so much lag I thought the turbo was shot, till it kicked in weakly. Good thing is from ebay bet you get a deal on an upgrade turbo that would probably, bolt on.

The turbo in my car is definitely on the too small side and it's from the factory. I don't misunderstand the specs at all. It really does make max torque from 1700 to 5000 rpm. Then it takes a nose dive. The turbo in this is operated damn near outside its efficiency map under certain conditions. The redline on the car is 6500 rpm but it poops out totally by 5800. BTW, my car is also direct injected and has VVT.

In the aftermarket, it won't even break 300 whp and that's with supporting mods like "larger" intercooler, 3" exhaust and intake.

Actually, the Ecotec LNF can take up 500 hp (crank) in stock configuration. So far we have people rocking 400 whp with just a turbo upgrade and some tuning. There are some issues with the stock ECU limiting boost to 255 kpa but GM's performance upgrade eliminates that limit (along with some other stuff like a CARB legal, warranty friendly 290 hp and 325 lb-ft of torque). Work is in progress on this engine!!!!
