GM tried the same performance emphasis with its EV1 battery car, but it was limited to about 90 miles of range. If Tesla has been able to achieve both high performance and long range, it39。s a step in the right direction, he says. I fill it up at the gas pump and it performs like any other car. But I fill it up about once every three weeks. The Prius is the benchmark by which all other hybrids are measured. TOYOTA CAMRY HYBRID: Like the Prius, the relatively new Camry hybrid actually runs on its batteries alone at low speeds. Under the hood is a fourcylinder engine that uses the Atkinson cycle for greater fuel efficiency. Add together the 147 horsepower gasoline engine and the 45horsepower electric motor and there39。s an ATPZEV, gets 49 miles per gallon (city) and 51 (highway), and has a range of 600 miles. If there39。 it39。s a good first step from a pany that says it wants to be an environmental leader but hasn39。s recent announcement, Paine said. But obviously they39。s more sanguine about GM now, since the pany announced both a production plug in hybrid car (see main story) and a battery electric with a gas motor used solely to keep those batteries charged. I39。t yielded the sales Honda had sought. Sales in 2020 were less than a fifth of the hybrid Civic. FORD ESCAPE HYBRID: The $26,900 Escape wins kudos as the first hybrid SUV on the market, achieving 36 mpg (city) and 31 mpg (highway) with a system that is similar to that in the Prius. It39。s in the $22,150 purchase price. But even that can be offset with federal ine tax credits, as well as state incentives if they apply. To get 115 horsepower out of a engine requires some wizardry. Under the hood is an Integrated Motor Assist system that uses its 20horsepower electric motor mainly as a power booster, plus a continuously variable transmission (CVT). Honda hopes to sell 28,000 in 2020. HONDA ACCORD HYBRID: Introduced at the end of 2020, the V6powered Accord Hybrid was freshened for 2020, with more standard features (including a moonroof and a real spare tire). Fuel economy suffers a bit with the car39。s not special, or weird, or for purists only. It39。s also an ATPZEV, which means that, unlike most cars on the road that emit gasoline vapor (and thus global warming gas) when parked, it has zero evaporative emissions. Jason Mark of the Union of Concerned Scientists39。s fuel cell propulsion system chief, these Equinoxes are closely based on the production SUV, and offer the latter39。t burn anything but converts hydrogen (stored in a tank as liquid or gas) to electricity and its tailpipe emission: water vapor. Fuel cells were invented in the mid19th century and provided electric power on NASA space missions, but they39。s kits for the Prius ($9,500) and Ford Escape (as yet unp
