Electric Vehicles
First off, an electric vehicle can be expected to add incredible
weight as it adds range. But a real benchmark was set. The Tesla Roadster has a range of over 240 miles while having a weight within 10% of a traditional car of comparable size. The Tesla Roadster weighs about 7.1% more than a Mazda MX5 with automatic transmission. Now the BYD E6 electric vehicle has hit the market including 40 taxis in Shenzhen. Also, note the range of 186 miles. But I'll compare this EV to a traditional vehicle: BYD E6 electric vehicle 5 seat crossover 179.5" length 71.7" width 64.2" height 5203 lb curb weight Nissan Rouge 5 seat crossover 183.3" length 70.9" width 66.3" height 3292 lb curb weight |

How does it get "a range of over 240 miles"? 10 mph? no heat, a/c, daytime only? Electric cars are nothing but electric paperweights. |

That could make the weight about 4400 pounds but that's still a big percentage over the traditional vehicle of comparable size. But the website says 5203 pound curb weight. The Tesla Roadster makes it's numbers with lithium ion batteries and with a Lotus designed vehicle frame. |
