That’s right. Tesla is actually naming their models like they are a gadget, or worse, a piece of software that they update regularly as they come across bugs and errors. One of the biggest bugs the original Tesla Roadster was afflicted with limited range. So in the new Roadster 3.0 they have addressed that with a bigass battery.

The highlight of the Tesla Roadster 3.0 is a 70 kWh lithium-ion battery pack that is actually the same physical size as the old one, but boasts bigger capacity cells inside. As a result, the 3.0 isa said to be able to deliver a real-world range of up to 400 miles (nearly 650 km) on a single charge. That is, of course, the manufacturer’s claim, not yet verified by an independent source.

Tesla Roadster 3.0 does not rely solely on its 31 percent more efficient battery to deliver the astonishingly good range. The car also benefits from various improvements in the mechanical parts, such as wheel bearings and low rolling resistance tires, and a revised aero kit that enhances the vehicle’s drag coefficient to 0.31.

Tesla will be showing off the capabilities of the 3.0 in a demo drive from  San Francisco to Los Angeles early next year. They hope to ready the car for the showrooms in spring.
