It’s much smoother and has the rail gun torque that I had read so much about. Also, the battery coolant pump now shuts down when parked (an irksome precaution in early models that is no longer needed).
The interesting back story is that a major redesign of the whole drivetrain was enabled by a breakthrough in the semiconductor industry – a new IGBT (power transistor) that just started shipping. Advances in the smallest of components unlocked a design cascade to remove the need for shifting altogether (no transmission) while also improving efficiency (longer range, higher performance, 30% more torque, 14,000 RPM redline).
The Tesla blog has the full story and gearbox photos from the CTO, J.B. Straubel.
Wikipedia Article
Tesla Motors, Inc. is a Silicon Valley-based company that designs, manufactures and sells electric cars and electric vehicle powertrain components. Tesla Motors is a public company that trades on the NASDAQ stock exchange under the symbol TSLA.
Tesla Motors gained widespread attention by producing the Tesla Roadster, the first fully electric sports car. Tesla also sells electric powertrain components, including lithium-ion battery packs, to other automakers, including Daimler and Toyota.
Market analysts have called for Tesla to focus its efforts on supplying powertrain components to major automakers, which have the resources to mass produce electric cars. Tesla's CEO, Elon Musk, has said he envisions Tesla as an independent automaker. Tesla has been developing the Model S, a fully electric luxury sedan. Although expensive, it is substantially cheaper than the Roadster. Eventually, Tesla Motors aims to mass produce fully electric cars at a price that would be affordable to the average consumer.
