In the field of electric cars nothing beats the Tesla Roadster. The style, the speed, and the MPGe rating— Tesla wins on all accounts. Now Tesla has raised the stakes again by introducing the Tesla Roadster 2.5 that boasts an MPGe rating of 112 MPGe on the highway and 124 MPGe in the city. This combined rating puts the overall MPGe for the Roadster 2.5 at 119 MPGe.
When the new 2.5 Tesla Roadsters will become available is anyone’s guess. However, with the original Roadster boasting an overall MPGe rating of 111 the improved 2.5 model is undoubtedly going to be a success. One interesting thing to point out is that other than the more efficient MPGe rating the rest of the Tesla Roadster 2.5 statistics remain unchanged from its predecessor; i.e. annual fuel costs, approximate range, and kW-hrs per 100 miles.
MPGe stands for Miles Per Gallon Equivalent. Since the Tesla Roaster, be it the original or 2.5, is fully electric there is no gas; so MPGe is used to measure the amount of energy used to travel a distance in relation to gas use. Why do this? Well, focus groups made up of everyday citizens showed that the average citizen could not conceptualize a kilowatt hour even though this is the same calculation used and posted on ones electrical bill every month.
So, the EPA had to come up with a new unit of measurement in order to help the public understand all those crazy and complicated numbers. Essentially, the EPA had to dumb stuff down so people could understand what they were talking about— if the EPA has to make up a new system of measurement to replace an existing system of measurement that is deemed to tricky by the masses, I guess this sort of puts the final nail in the coffin for the metric system ever being adopted in the U.S.
One must at least admire the creativity shown by the EPA and the technological advances that continue to come from Tesla. Expect to see an MPGe rating on all electric, flex fuel, and alternative fuel vehicles starting in 2013.
