![]() ![]() But its the three extended-range modes (meaning the engine is on) used after the. EPA combined economy in range-extending mode is up from 37 mpg (6.4 L/100 km) to 42 mpg (5.6 L/100 km). The second-generation 1.5L engine boasts 20 more power and 10 more torque vs. In the new Volt, Motor A substitutes a ferrite magnet, reducing its cost, while Motor B continues to use neodymium. The second generation Volt also benefits from a reengineered and re-packaged two-motor drive unit that is said to operate 5 to 12 percent more efficiently than the current system and weighs 100 pounds (45 kg) less. Official EV-only range is 53 miles (85 km), 40 more than the previous 38 miles (61 km). ![]() “So our team created a new battery system that will exceed the performance expectations of most of our owners.” “It would have been simple for us to tweak our existing battery to provide nominally increased range, but that’s not what our customers want,” said Larry Nitz, executive director of GM Powertrain’s electrification engineering team. There’s a new lithium ion battery pack with revised cell chemistry made in cooperation with LG Chem, which increases storage capacity by 20 percent on a volume basis when compared to the original cell, while the number of cells decreases from 288 to 192. The optional range extender gasoline engine costs about 4,000 extra, and lengthens the vehicle’s effective range from 72 miles to 150 miles. Neither nitpicking about nomenclature-nor posturing with hype-is worth the trouble.GM has replaced the previous 1.4-liter four-cylinder range-extender engine with a larger, but more fuel efficient, 1.5-liter unit that will initially be built at GM’s Toluca, Mexico engine plant for the first year of production, then shift to the Flint, Michigan engine plant. EVs also have a place in our diverse-mobility future, just as diesel, compressed natural gas and hydrogen fuel cells will play roles as well. Hybrids of all varieties have proven to be efficient-and generally cost-effective-means of achieving better-than-traditional fuel consumption and cleaner-than-traditional emissions. Oh, and let's not forget whether one buys into all this at $41K minus tax benefits. Rather, it will be in customer acceptance of its now reported "25 to 50 miles" EV range (note, not steadfastly 40 as hitherto often quoted) and how transparently the gasoline engine kicks in-either after that EV range is exhausted or in high-speed operation. The proof of the Chevy Volt's concept shouldn't be in its technical definition nor in mpg arithmetic. ![]() Take your pick: mid 30s to more than 1200 mpg. #Chevy volt range extender engine generatorAlas, this disclosure comes after considerable posturing of GM for the past three years that the Volt was to be a paradigm shift and not just another hybrid.īut who really cares whether the car is A) a range-assisted EV i.e., a series hybrid, its gasoline engine solely dedicated to driving its electric generator on demand, or B) a more familiar hybrid of the series/parallel variety, in which that engine occasionally drives a generator, occasionally propels the car-and as in A) occasionally shuts down completely.Īlso, does anyone actually believe the 230-mpg hype concocted by GM? Succinctly, it all depends on how many miles you drive between plug-ins. Indeed, at high speed, its gasoline engine also contributes directly to the Volt's progress-not unlike "conventional" hybrids such as the Toyota Prius. The latest word from Chevrolet is that its Volt isn't purely an EV with range-extender gasoline engine. ![]()
