A special report from the EVS23 Electric Vehicle Symposium
The trend is clear: All the electric vehicles (EV) that emerged in the last decade and a half have vanished. The Ford Ranger EV, General Motors EV1, Toyota RAV4 EV, and others are all gone. The disappearance of such promising vehicles inspired the film "Who Killed the Electric Car?" Well, they're not dead, yet.
At the EVS23 Electric Vehicle Symposium I attended in Anaheim, CA in early December, I drove a few upcoming electric cars. Some were clunky, slow and vulnerable and didn't seem more advanced than other attempts we sampled a decade ago. However, two of them really stood out as viable vehicles in terms of performance and practicality. The price, however, could prove prohibitive.
The eBox by AC propulsion
The eBox is a previous-generation Scion xB that's gutted to rid itself of the original engine and transmission. It's converted by a company called AC Propulsion and uses the same technology found in the Tesla roadster. The eBox uses an electric direct-drive system, so there's no need for a shifter. Instead, there's a controller that interfaces with a special display on top of the steering column. Regenerative braking - the capture of braking energy that is channeled through the motor to recharge the batteries - can be adjusted. Under the front seats resides a 400-volt lithium-ion (Li-Ion) battery pack. It has a 120-mile range and takes two hours to charge through a 220-volt outlet; hooking it up to a regular household 110-volt outlet doubles the charge time.
On the road, the eBox feels quick and quiet. The company says it will reach 60 mph in seven seconds and has a top speed of 100 mph. In the most aggressive regenerative braking setting, decelerating takes place by lifting off the throttle, which I found to be quite abrupt. With practice, you can actually drive the car without using the brakes. With the conversion adding a whopping 600 pounds to the vehicle, you'd think that the ride and handling might be somewhat challenged. AC Propulsion President Tom Gage says that spacers have been added to the springs and the tire pressure was increased, but acknowledges that even with two passengers on board, the load exceeds the gross vehicle weight limit of the xB (a mere 825 pounds). However, the xB's stiff suspension seems to pull it off. The eBox costs $55,000, not including the Scion xB.
Phoenix SUT
This odd-looking compact pickup is actually a Korean model called the Ssanyong Actyon that's sold outside of North America. It's roughly the size of a Toyota Tacoma and will be offered for sale here starting in spring 2008 through a company called Phoenix Motorcars that converts it into electrical vehicle. It's intended for fleet buyers. Another version, converted by a company called Boshart Electric Vehicles, is intended only for low-speed use, such as patrolling malls and the like.
Under the Phoenix's truck bed resides a tray that contains a 435-volt lithium-titanate battery. This type is the next generation of the Li-Ion and is said to be more advanced, especially in withstanding cold and hot temperatures. It will be warranted for 250,000 miles or 12 years. It has a claimed range of 130 miles. The claimed consumption is 320 watts per mile. A full recharge takes 12 hours through a regular household 110V outlet, but there's a ten minute rapid recharge capability using a special industrial charger.
On the road, this truck felt very responsive and quiet. The 405 ft-lb of torque launches the 4,600-pound truck decisively; it seems like it could lend itself to towing. I did not experience the truck's claimed 95 mph top speed. The truck will be offered with a 268 hp electric motor. The company intends to use the four-wheel-drive version of the truck minus the live rear axle and propshaft to better utilize the space between the frame rails and the bed for the battery tray. This gives the vehicle front-wheel-drive as well as the electric powertrain - most unique combination for a pickup.
The price starts at $47,500 for the truck, or $49,000 for the SUV version that will follow. So far, the company has orders from Pacific Gas, the City of Sacramento, and the Port of Los Angeles.
After seemingly reaching a dead end, EVs might be making a comeback... albeit in very limited numbers and at enormous cost. For now, it looks like these vehicles will be sold mostly for commercial and fleet purposes, where the vehicles follow a prescribed route and can be charged overnight. Still, it's nice to see the technology evolving. Such development could benefit all who hope for cleaner air, sustained mobility, and less dependence on foreign oil.
