...what about m.p.k. and k.p.m. comparisons? And what about MPGGE and GHGP? It's the new language in your car future...
...Fritz Henderson announced this week that the company's much anticipated Chevy Volt (half electric, half fossil fuel) is the undisputed winner in the miles-per-gallon race, claiming that under new EPA guidelines the Volt will hit 230 miles per gallon (city), the first car to ever earn triple-digit fuel efficiency. Not to be outdone, Nissan fired back a few days later to its Twitter base of fans that its just-announced all-electric Nissan Leaf would be rated at 367 m.p.g., also using EPA guidelines. (See the 50 worst cars of all time...
...bases its 230-m.p.g. boast on a blend of the Volt's electric-only mode - which has a 40-mile-range limit - and charge-sustaining mode, with its 1.4-L electric generator running. (The generator is a small gas-powered engine that keeps the batteries charged while the car is being driven, hence the "extended range...
...Here's the breakdown: The 230-m.p.g. number, according to GM's Frank Weber, global-vehicle-line executive for the Volt, is a measurement of the car's "city-driving cycle" - that's the 40 miles it can go without gas, plus one daily electric recharge, plus a little extra help from the gasoline it might need to continue to charge its batteries when they get low during driving in the city. It's basically measuring the Volt's electric-only-mode (with some help) mileage capacity. If the Volt got out on the highway - where it's powered largely...
...says the EPA will weight plug-in electric vehicles as traveling more city miles than highway miles on only electricity, presumably figuring that people buy electric cars primarily for local driving. GM expects the Volt to consume 25 kilowatt hours per 100 miles of city driving. At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for enough electricity to travel 100 miles, or less than 3 cents per mile. (Conversely, a gasoline-powered car that gets 20 m.p.g., for which the driver pays $3 per gallon...
