![]() The ability to manufacture them from a few basic components will help achieve economies of scale that will translate into lower prices for the vehicles they are installed in. EVs from every GM brand - Buick, Cadillac, Chevrolet, and GMC - will utilize the components as well as future Honda and Acura models. ![]() They may be used in the next-generation Chevy Bolt or in high-performance cars like the Chevy Camaro. The motors will be packaged with an inverter and gearset in various combinations to go into a generation of fully electric vehicles ranging from the GMC Hummer to family sized crossovers like the Chevrolet Equinox. (I suggested doing something like this to Saturn back in 1996. The company has designed three electric motors in-house - a 180 kW (240 hp) permanent magnet motor for front-wheel-drive applications, a 255 kW (315 hp) permanent magnet motor that can be used in front or in back, and a 62 kW (83 hp) all-wheel-drive assist induction motor that can be used in front or in back. In a recent interview with Green Car Reports, Tim Grewe, GM’s head of global electrification strategy, talked about the electric motors and software controls that will be part of the Ultium platform. It can add more battery modules or use fewer of them. It can be make wider or narrower, as the needs of the company require. Like the MEB platform Volkswagen is using for most of its new electric car offerings, the Ultium chassis can be lengthened or shortened to fit a variety of vehicles. Ultium is actually GM’s name for its entire electric vehicle platform that will be the basis for all of its electric cars going forward. In fact, the two companies have agreed to build a second battery factory near the Spring Hill, Tennessee, facility where the Cadillac Lyriq will be produced. ![]() We have heard a lot about the Ultium batteries GM is manufacturing with its partner, LG Energy Solution, at a new factory in Lordstown, Ohio. More efficient cars go further on a single charge and may need smaller (and less expensive) batteries to meet the needs of the motoring public. In the new world of electric cars, efficiency is the key parameter. ![]() In the old days of cars, cubic inches were the first thing on everyone’s mind. ![]()
