Jaguar Land Rover, a subsidiary of Tata Motors, has received a grant worth 27 million pounds--more than $37 million--to mass-produce a "green" crossover vehicle.

The car will be a street version--or a more practical variation--of the LRX concept vehicle that Jaguar Land Rover debuted at the Detroit Motor Show in January 2008.

The concept version was a hybrid 2-liter turbo diesel crossover vehicle, combining features of a car and an SUV. The concept got about 50 mpg on average, according to its specs.

Jaguar Land Rover's announcement comes as the U.K. government held a meeting Wednesday … Read more

Tesla Motors has begun offering its Roadster electric vehicle for the Canadian highway, the company announced Wednesday.

Tesla said in a statement that driving a Tesla Roadster in Canada can be thought of as even more kind to the environment than in other places since the bulk of the country's electricity is generated from renewable resources.

"An EV recharged from the current Canadian grid, on average, would reduce greenhouse gas emissions by about 85 percent compared to an equivalent gasoline-powered vehicle. In hydro-dominant British Columbia, Quebec, and Manitoba, the reduction would be an impressive 98 percent," said … Read more

Nissan unveiled its Qazana crossover vehicle at the 2009 Geneva Motor Show on Wednesday.

The concept was inspired by beach buggies, according to Nissan. With its oversized tires it does look like some sort of futuristic rally car.

The ultra-low rolling resistance tires, which enable a car to get better gas mileage, were made from nano technology materials by Kumho Tyres, a U.K. company known for its eco-credentials.

An obvious younger sibling to the Qashqai SUV sold in Europe, the Qazana is a very compact hatchback at approximately 13 feet long and 6 feet wide. (For comparison, BMW's … Read more

RUF Automobile and Siemens Corporate Technology, the research arm of Siemens, debuted their all electric car concept at the Geneva Motor Show this week.

The Greenster, like its name suggests, is designed to look like a roadster vehicle of yesteryear complete with plaid seats. But the tech speaks to the 2000's interest in green technology.

Siemens is providing technology for the car's power train which includes the motor/generator, the power electronics, and the interface with the car's battery.

The Greenster concept car displayed at the Geneva Motor Show had only one motor. But the Pfaffenhausen, Germany-based … Read more

What's green, weighs 650 pounds, goes 3.5 mph, and costs more than $25,000?

Not something you or I will ever buy, but a gadget golf course superintendents may go gaga over.

The RG3 (Robotic Greens Mower 3) from Precise Path debuted a few weeks ago at the 2009 Golf Industry Show in New Orleans. It's a robot lawnmower that uses two lead acid batteries to run its 24-volt DC motor, and one to run its computer, offering about three hours of mowing before needing to be recharged.

"Our robot could provide the human precision necessary to upkeep, actually better than a human is capable of, and not costing the large amount in intensive labor costs," Precise Path co-founder, president, and CTO Doug Traster told CNET News in a phone interview.

The founders of the company decided to craft a robot lawnmower for the golf industry because they saw a need that could be filled with a bot, and an industry that would not scoff at a hefty price tag for high-tech maintenance equipment. While the company hopes to continue to develop the tech to bring the price down, right now the RG3 has a suggested retail price of $29,500.

In addition to mowing golf greens, the company is developing add-ons for the device that would allow golf course superintendents to use the robots to also mow fairways, rake sand traps, and spot treat with pesticides and fertilizers.… Read more

The city of San Francisco is installing three EV (electric vehicle) charging stations across the street from city hall as part of a two-year pilot project to promote electric vehicle use, San Francisco Mayor Gavin Newsom announced Wednesday at a press conference.

The Smartlet Networked Charging Stations supplied by Coulomb Technologies will serve hybrid electric plug-in vehicles from Zipcar, City CarShare, and the city's municipal fleet, according to a statement from the mayor's office.

Because the EVs will be readily available for daily rental, skeptics and enthusiasts alike will have a chance to see what it's like to drive an electric car for a day.… Read more

Correction, 12:55 p.m. PDT March 19: Global Solar is not technically a subsidiary of Solon as was suggested by the analyst. According to Global Solar, Solon acquired a 19 percent stake in 2006. The remaining 81 percent is owned by a European venture capital investor.

One year ago, silicon, the most common material used in making solar panels, could not be supplied fast enough. It gave an opening to many new solar tech start-ups looking to pick up venture capitalist interest and cash.

While some technologies may not have been as efficient as traditional silicon solar panels, they … Read more

Mitsubishi released a more detailed sketch of its Prototype i Miev on Thursday.The all-electric sports car concept is set to debut at the Geneva Motor Show this March alongside the i Mieve Sport Air concept car.

Both are follow-ups to Mitsubishi's i Miev hatchback, which is currently undergoing "feasibility testing" in Europe. The hatchback, which is scheduled to go on sale in Japan sometime this year, can be plugged into any household outlet for recharging.

Though at 7 hours to recharge at 200V outlets and and 14 hours at 100V outlets, owners may opt for a … Read more
