In a power-split hybrid electric drive train there are two motors: a traction electric motor and an internal combustion engine. The power from these two motors can be shared to drive the wheels via a power split device, which is a simple planetary gear set. The ratio can be from 100% for the combustion engine to 100% for the traction electric motor, or anything in between, such as 40% for the electric motor and 60% for the combustion engine. The combustion engine can act as a generator charging the batteries.
A New England native, I have piloted a wide variety of vehicles, from a Segway to an aircraft carrier. All told, I have driven thousands of vehicles—many on race tracks across the globe. Today, that experience and passion are harnessed at the CR Auto Test Center to empower consumers. And if some tires must be sacrificed in the pursuit of truth, so be it.

Variant diesel electric locomotive include the Green Goat (GG) and Green Kid (GK) switching/yard engines built by Canada's Railpower Technologies, with lead acid (Pba) batteries and 1000 to 2000 hp electric motors, and a new clean burning ~160 hp diesel generator. No fuel is wasted for idling — ~60–85% of the time for these type locomotives. It is unclear if regenerative braking is used; but in principle it is easily utilized.
In Latin prius is the neuter singular of the comparative form (prior, prior, prius) of an adjective with only comparative and superlative (the superlative being primus, prima, primum). As with all neuter words, the Latin plural is priora, but that brand name was used by the Lada Priora in 2007. Despite the "official" plural form used by Toyota USA, "Priuses" is widely used in English.[21]
A SHEPB prototype made by David Kitson in Australia[6] in 2014 used a lightweight brushless DC electric motor from an aerial drone and small hand-tool sized internal combustion engine, and a 3D printed drive system and lightweight housing, altogether weighing less than 4.5 kg. Active cooling keeps plastic parts from softening. The prototype uses a regular electric bicycle charge port.
The second generation Prius plug-in, called Toyota Prius Prime in the U.S. and Prius PHV in Japan,[86] was developed in parallel with the standard fourth generation Prius model (XW50) released in December 2015.[87] The model was released to retail customers in the U.S. in November 2016,[13] followed by Japan in February 2017.[82] In the American market, unlike the first generation model, the Prius Prime will be available in all 50 states.[87][88] Cumulative global sales of both Prius plug-in generations totaled 79,300 units at the end of January 2017.[12] The U.S. is the top selling market, with 46,133 units sold since inception through January 2017, of which, 3,788 units are second generation Prius Prime cars.[83][84]
Toyota unveiled the Prius c concept at the January 2011 North American International Auto Show. The Prius c has a lower list price and is smaller than the previous Prius hatchback. The production version was unveiled at the 2011 Tokyo Motor Show as the Toyota Aqua, and was launched in Japan in December 2011.[94] The Prius c was released in the US and Canada in March 2012,[95][96] and in April 2012 in Australia and New Zealand.[97][98] The Prius c is not available in Europe, where instead, Toyota is selling the Toyota Yaris Hybrid since June 2012.[99] The Prius c and the Yaris Hybrid share the same powertrain.[100] The Aqua ranked as the second best selling car in Japan in 2012 after the Prius brand, as Toyota reports together sales of the conventional Prius and the Prius α.[101][102] When sales of these two Prius models are broken down, the Toyota Aqua ranked as the top selling model in Japan, including kei cars, with the Aqua leading monthly sales since February through December 2012.[103][104] Thereafter, the Aqua has been the top selling new car in Japan for three years running, from 2013 to 2015,[105][106][107] and it is considered the most successful nameplate launch in Japan in the last 20 years.[108]
