6Report: General Motors working on diesel hybrids for Opel, Vauxhall

If you want to maximize you fuel efficiency in the city, your best bet is probably a hybrid. On the flip side of the coin, if you do most of your driving on the open road, diesel engines tend to be much more economical than their gasoline-powered siblings. What if you could combine the two, though, and end up with the best of both worlds?

14REPORT: Toyota to give hybrid technology to GM?

According to a report in Japan's Daily Yomiuri newspaper, Toyota is willing to give General Motors access to its hybrid technology, free of charge. Why in the world would they do that, you ask? Apparently, Toyota doesn't want to see the crucial American market weaken any further and would benefit from the exchange by having its Hybrid Synergy Drive become the standard hybrid technology all over the world.

34Hybrid sales slide 9.9% in 2008

Despite all the clamor about how hybrids are going to save the planet, cure cancer, facilitate the second coming, etc., sales of battery-pack-mobiles are down nearly ten percent for 2008. At the beginning of 2008, it looked like hybrids were going to have their best year ever, driven by high fuel prices and a recessive economy. That recession, however,has caused consumers to cut way back, leading to dramatic drop in fuel prices, killing much of the argument for a hybrid's price premium. Consumer

42GM sold 2,555 hybrids in December, HUMMER sales cut in half

All things considered, it appears that we think of GM's 2,555 hybrid sales in December a success. GM's press release (posted after the jump) certainly makes it all smell like roses. The 2.5k deliveries are up from the 1,957 hybrids the General sold in September. At that time, GM was averaging about 1,000 hybrids a month for 2008, and the trend has been upward since then, and for all of 2008, GM sold 14,439 hybrid vehicles. Here's how December's hybrid sales broke down:

AddGMC Yukon hybrid featured in Macy Parade

General Motors is the Official Vehicle Supplier for the Macy Thanksgiving Day Parade. There, now you've learned your requisite something new for the day. This year, The General decided to trot out hybrid versions of the full-size GMC Yukon to pull various parade floats and giant balloon-things. Oddly, GM did absolutely nothing to advertise the fact that it would be having the hybrid 'utes take place in the event, leaving various other media outlets to find out about it themselves. No matter. Fin

49Wagoner: GM didn't build hybrids because nobody wanted them

"We have to build cars and trucks that people want to buy." So said Rick Wagoner, head of General Motors, at a recent conference in Dallas, Texas in response to why GM didn't begin offering hybrid cars earlier. Yeah, Rick, that's entirely true. But, your company also has to have at least a modicum of foresight in order to be successful in the tough American market these days. For instance, Toyota is just now reaping the benefits of its hybrid electric vehicles, despite the fact that the automake

3GM hybrid finally starting to get a little traction, 1,149 in June

With five hybrid models on the market now and at least four more coming before the end of the year, General Motors' hybrid sales are looking less ugly than they did in the first three months of 2008. GM is still no threat to Toyota or even Ford, but sales have been steady (if slow) for the last couple of months. For the first time in their monthly sales report for June, GM has explicitly said how many hybrids were sold. Amidst truck sales that were down 39 percent compared to June 2007, GM decla

11General Motors plans to purchase Cobasys outright

Shortly after reports of leaky batteries coming from Cobasys, which greatly slowed the production of GM's mild hybrid vehicles, such as the Saturn Vue and Aura hybrids and Chevy Malibu hybrid, comes a report from Automotive News which suggests that General Motors may just purchase the troubled battery maker outright. That's one way to manage the problem, wouldn't you say? Though GM would own 100-percent of Cobasys, some sort of partnership is said to be in the works, though that other entity rem

26Doh! Battery leakage hurts GM hybrid production

As much as General Motors would like to sell more hybrids, we'd imagine it would be pretty tough to do so without having the batteries on hand. It turns out that since December of last year, GM has had to recall some nine-thousand battery packs produced by its supplier, Cobasys, which were due for installation in mild hybrid versions of the Chevrolet Malibu, Saturn Vue and Saturn Aura. The culprit was reportedly an internal leak in the pack which caused the entire unit to be inoperable. This set

22Hybrid sales at GM looking slightly less barren in April

A month ago during GM's monthly sales conference call, it was revealed that the company had sold a measly 843 hybrid vehicles in the first three months of 2008. Although I don't partake in the most recent sales call, one of the readers over at TTAC did listen in this month and someone specifically posed the question of how many hybrids GM managed to move off dealer lots in April. As usual GM didn't break out hybrid sales in the overall numbers but when questioned, Marketing boss Mark LaNeve did

26Are GM and Toyota working on a hybrid together?

The evidence: rumor had it at the LA Auto Show that customers would soon have the option of buying a hybrid Toyota Matrix and a hybrid Pontiac Vibe; the 2009 Pontiac Vibe is made at NUMMI, a GM-Toyota joint venture manufacturing plant where the Matrix is also made; Toyota's already got its hybrid synergy drive -- so is GM working on a hybrid with Toyota, or will they use Toyota's hybrid tech to work in the Vibe?

22Detroit Auto Show: General Motors' E-Flex platform

In conjunction with the Detroit Auto Show introduction of the Chevrolet Volt concept, General Motors is also unveiling an entirely new vehicle architecture that they've dubbed "E-Flex". As the name implies E-Flex is a platform for electrically driven vehicles. The key to this platform, though, is the inherent flexibility they've designed in. During the presentation of E-Flex Beth Lowery, GM Vice-President Energy and Environment talked about the future of energy supplies. GM sees diversity as one

16GM unveiling surprise concept on Sunday

With all the broken embargoes lately, we were expecting NAIAS to be no more a surprise than what we bought ourselves for Christmas (socks, btw). But look there! What's that behind the sparkling Auto Show tree? A gift from none other than Mark LaNeve, GM Vice President of Sales and Marketing, with a note that says do not open until Sunday.

4GM Awards two lithium-ion battery contracts for PHEV Saturn Vue

General Motors is moving forward on their plans for a plug-in hybrid version of the Saturn Vue that chairman Rick Wagoner announced at the Los Angeles Auto Show. Today they are awarding development contracts to Cobasys and Johnson Controls-Saft to create and test lithium-ion batteries. The companies will supply battery packs that will be installed in prototype vehicles with testing to begin later in 2007. Both companies are working on different battery technologies that will be evaluated by GM f

2EDTA Conference: The East Coast GM plug-in hybrid announcement

The media spotlight was on GM Chairman Rick Wagoner and the big announcement yesterday at the Los Angeles Auto Show that GM would offer a plug-in hybrid sometime in the next few years. Over at the EDTA Conference, where such an announcement would have been right at home, the news was delivered to attendees Wednesday afternoon by Pete Savagian, engineering director of GM hybrid powertrains. When Savagian mentioned the announcement, people clapped and cheered. The news seemed to validate a lot of
