Tesla Roadster

The Tesla Roadster is one of the earliest electric production sports cars (if not the first one), and it helped change the public perception that electric vehicles were slow, with a 0-60 MPH acceleration time of 3.9 seconds. Tesla Motors eventually released the Tesla Roadster Sport which could make 0-60 MPH sprint in 3.7 seconds.

The car was first unveiled on July 19, 2006 in Santa Monica, California at an invitation-only event in Barker Hangar  at Santa Monica Airport. The first Tesla Roadsters were delivered in 2008. During the first two months of production (before regular series production started), only three vehicles were produced: P3/VINF002, P4/VINF004, and P5/VINF005.

Article Glossary

Wh/mile: Watt-hours of energy consumed by the vehicle per mile.

RWD: Rear-Wheel-Drive.

kWh: Kilowatt-hour.

Extended-range/EREV: EREV means extended range electric vehicle. Such vehicles are electrically propelled. However, a backup generator is present to provide them with electricity if needed.

Gravimetric energy density (of a battery pack): Also known as energy-to-weight ratio: This is the amount of energy stored per kg of a given battery pack’s weight.

Volumetric energy density: Also known as power-to-size ratio, this is the amount of energy stored per litre of the battery’s volume. This is basically a measure of how compact the battery pack is.
