Genovation Cars readies all-electric Corvette prototype

Chevy runs the full spectrum from some of the most environmentally friendly cars to the least. At one end are EVs like the Spark and Volt. At the other, performance models like the Camaro and Corvette. But one American company wants to bridge that divide. That company is Rockville, MD-based Genovation Cars, which reports that it is almost done building its prototype for an all-electric Corvette. Dubbed the Genovation Extreme Electric (or GXE for short), the prototype is based on a previous-generation 2006 Chevy Corvette Z06, but ditches its enormous 7.0-liter V8 for an array of inverters, batteries, and electric motors said to be good for over 700 horsepower and 600 pound-feet of torque. That promises to deliver a 0-60 time of about 3.0 seconds and a top speed in excess of 200 miles per hour. Those are supercar benchmarks for performance if we've ever seen them, and ought to leave even the top-spec Tesla Model S P85D in... well, not a cloud of smoke, but whatever the electric equivalent is, in a non-polluting cloud of that. The GXE is also supposed to be able to travel for 150 miles on a single charge, and handle well while it's at it with 50/50 front-rear weight distribution and a low center of gravity. Sorta like the Power Wheels 'Vette pictured above, then, but bigger and faster. Look for the GXE to debut at the Electric Vehicle Technology Expo this coming September in Michigan, after which Genovation says it will put the GXE to the test on the track to back up its performance claims. Genovation Cars Nearing Completion of High-Performance All-Electric Corvette, the GXE ROCKVILLE, Md.--(BUSINESS WIRE)--Genovation Cars is nearing the completion of a prototype high-performance all-electric Corvette called the Genovation Extreme Electric or GXE. Assembly of the GXE will be completed by the end of July, followed by a three-week testing phase. The GXE is based on a 2006 Z06 Corvette. Several contributors to the GXE effort have helped design and build record-breaking electric vehicles. They include an MIT electrical engineer and a mechanical engineer from Cosworth. "We are using state of the art inverters, batteries and electric motors that will produce in excess of 700-hp and 600 lb-ft of torque," said Genovation CEO Andrew Saul. "We expect the car to achieve 0-60 mph in around three seconds and have a top speed of over 200 mph.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Smaller Cars Endure Big Problems On Crash Test

In a crash test of 11 of the smallest cars on the market, only one vehicle received an acceptable rating. The rest received marginal or poor ratings in the study, providing evidence that supports a widely held notion that smaller cars are among the least safe on the road. No other vehicle group has performed as poorly on a new crash test than these mini cars, says the Insurance Institute for Highway Safety, the nonprofit group that conducted the testing. The latest results of which were released Wednesday. The Chevrolet Spark was the only car earning an overall "acceptable" rating on the small-front overlap test, and even that vehicle had its shortcomings, IIHS said. "Small lightweight vehicles have an inherent safety disadvantage," said Joe Nolan, the senior vice president for vehicle research at IIHS. "That's why it's even more important to choose one with the best occupant protection. Unfortunately, as a group, minicars aren't performing as well as other vehicle categories." The Mazda2, Kia Rio, Toyota Yaris and certain Ford Fiesta models all received "marginal" overall grades on the test, while the Mitsubishi Mirage, Nissan Versa, Toyota Prius C, Hyundai Accent, Fiat 500 and Honda Fit all earned "poor" ratings. Results from these sub-compact cars fare much worse than vehicles sized just a little bit bigger, IIHS said. Among 17 cars evaluated in the small category, five earned "good" ratings and five more earned "acceptable." Only introduced a year ago, the small-front overlap test has quickly become a key indicator of differences in automotive safety. IIHS introduced it as a way to replicate what happens when the front corner of a vehicle collides with a tree or utility pole at 40 miles per hour. In the real world, these sorts of accidents are more dangerous than others, in part because they bypass the front-end crush zones on most cars.
