Hybrids and green

City buses, streetcars, and regional rail lines all over the world run on electricity, garnered from overhead lines. Now Siemens wants to apply the same technology to long-haul trucking with its eHighway concept.

Siemens, an industrial and automotive supplier, contends that the majority of vehicle pollution comes from big diesel trucks transporting goods over many freeway and highway miles. Its eHighway would eliminate tailpipe pollution from these trucks for the majority of those miles.

On a test track in Europe, Siemens has been running trucks using its diesel-hybrid drive technology. Conductors on top of the trucks make contact with overhead … Read more

Toyota showed off its RAV4 EV, the electric version of the RAV4 compact SUV, as a concept about a year and half ago at the 2010 Los Angeles Auto Show. The wraps came off the production version of this new electric car this week, showing some speedy automobile development indeed.

More impressive is that the deal between Toyota and Tesla to develop the electric RAV4, on the heels of Toyota's decision to sell Tesla its NUMMI auto manufacturing plant, came less than two years ago. This is a car with a completely different drivetrain than that of the car on which it is based. Most model updates take longer to put into production.… Read more

RYNO Motors' single-wheeled electric scooter is self-balancing, has a turning radius of zero when stopped, and only takes up about as much space as a folding bicycle -- so it's conceivable that commuters could bring one onto a train. Plus, it looks like it fell out of a Japanese anime.

However, it only has a maximum range of 20 miles between charges, a top speed that is limited to 12.5 mph (the actual top speed of 25 mph is limited to keep the RYNO scooter within the more relaxed legal boundaries of "personal mobility scooters"), and it looks like it fell out of a Japanese anime -- yes, for some people, that last point is as much a con as it is a pro.… Read more

Croatian automotive startup Rimac has officially opened the order books for the electric supercar it debuted at the 2011 Frankfurt Auto Show. Only 88 of these exotic vehicles will be produced, but don't feel like you have to rush to order. Rimac may have a hard time finding buyers willing to throw down the near $1 million it will take to purchase the Concept One.

The Concept One went on sale at the start of the Top Marques Monaco, where Prince Albert II of Monaco spent some time behind the wheel of the EV. It's priced at $980,… Read more

Audi proved the worth of its diesel engine technology with a win at the 2006 Le Mans, breaking new ground for the legendary endurance race. This year, Audi ups the ante with two cars using hybrid diesel-electric drive systems.

The drive technology, branded by Audi as e-tron, uses a V-6 turbo-diesel engine on the rear axle, and an electric motor on the front axle. Similar to Kinetic Energy Recovery Systems (KERS) being deployed in F1 racing, the Audi R18 e-tron quattro captures braking energy in a flywheel. The car can then convert the energy of the spinning flywheel into electricity, … Read more

Automakers have endorsed a connector to charge electric vehicles in as little as 15 to 20 minutes, a technology which promises to make public charging stations more compelling.

German and U.S. automakers Audi, BMW, Chrysler, Ford, General Motors, Porsche, and Volkswagen yesterday issued a statement saying they will support the same charging interface.

Called the Combined Charging System, the standard can charge electric vehicle batteries with alternating current from a home outlet, direct current from a home outlet, or "ultra-fast" direct current from public stations. The system will be demonstrated next week at the International Electric Vehicle … Read more

Toyota will officially unveil the RAV4 EV next week, an all-electric SUV that could be an important indicator of electric vehicles sales overall.

The company earlier this week sent out a notice that it will debut the RAV4 EV on Monday May 7 at the International Electric Vehicle Symposium (EVS26) in Los Angeles, an important conference for EVs.

Toyota has shown off concept RAV4 EVs already, but important details such as price and availability have not yet been disclosed.

The all-electric SUV is the fruit of a partnership between Toyota and Tesla Motors, which is supplying the electric powertrain for … Read more

Ever since hybrids became popular, with the second generation of the Toyota Prius, the question arose of whether the fuel savings justified a hybrid car's higher price. The extra expense for a hybrid car has been called the hybrid premium.

The extra cost for a hybrid car comes from the additional equipment in the driveline. Along with the gas engine, hybrid cars have an electric propulsion motor, a high-voltage battery pack, and a power control module, this latter component determining how to feed electric power into the drive system.

Now, with many automakers offering some type of hybrid car, … Read more

General Motors debuted another rendering of the second-generation EN-V at the 2012 Beijing Auto Show, announcing at the same time that China will be its first testing grounds for these electric pods.

The EN-V, which stands for Electric Networked Vehicle, is a two-seater electric vehicle that will be capable of communicating with other vehicles and can be driven autonomously or manually. GM designed this concept for congested megacities of the future, and hopes it will help ease parking, traffic, and pollution in dense urban environments. For that reason, it makes sense that Beijing or another city in China will host … Read more
