The 2007 Frankfurt auto show officially opens to the public on Saturday, but we've been getting a preview of the automotive delights on display for the past couple of days. CNET Car Tech Senior Editor Wayne Cunningham has been busy scouring the show floor to bring you a whole slew of picture galleries. His roundup of the show's speed kings includes close-ups of the V-8 BMW M3, the Porsche 911 GT2, and the Mercedes C63.

Meanwhile, Frankfurt is showing off its fair share of concept cars, including the futuristic Nissan Mixim and the Porsche Cayenne hybrid. Among the new models on show, BMW's 1-Series sedan and updated 6-Series coupe have been real crowd-pleasers, as has the production version of Volkswagen's Tiguan crossover.

2007 Frankfurt auto show: Day two roundup

The new models and concept cars just keep on coming at the 2007 Frankfurt auto show. One notable trend at this year's event is the willingness of luxury German automakers to finally embrace hybrid technology, with Audi, BMW, Porsche, and Mercedes all either announcing production hybrids or showing off advanced hybrid concepts. Meanwhile, the 2009 Jaguar XF shows that concept technology can make it off the auto show floor, as the latest Big Cat retains its futuristic shifter for production. On the subject of cabin gadgetry, automotive equipment manufacturer Siemens VDO showed off its next-generation in-car touch screen technology, among other things, while Mercedes used its F700 research vehicle to demonstrate a prototype of a new version of its COMAND interface. All this plus a badass million-dollar Lamborghini, a look at the clean diesel-hybrid vehicles of the future, and tons more from the show can be found over on our new Car Tech blog, right here. [...]

2007 Frankfurt auto show: day one round-up

We've been trawling the floor on the first day of the Frankfurt auto show, and there have been plenty of new model launches and concept car unveilings to keep us busy. Mercedes Benz delivered on its promise to take the wraps off a fleet of new cars, including hybrid versions of its C300 wagon and its ML450 SUV, as well as its F700 research vehicle. Volkswagen and BMW also took advantage of being on their home turf, with the latter unveiling its partnership with Google for a local-search-enabled in-dash navigation system, and VW showing off its up! concept, an ultra-compact rear-engined mini-Golf with removable seats. Meanwhile, Fiat's own microcar, the 500, turned out not to be so micro in the flesh.


On the hybrid front, GM showed off its E-Flex-powered Opel Flextreme concept complete with built-in Segways, while Honda displayed a sport-tuned version of its Civic Hybrid that had earned its stripes racing in the 2007 Nurburgring race. Check out our continuing coverage of the show on the new CNET Car Tech blog, here. [...]

GM goes electric in Frankfurt

The future of electric propulsion...
(Credit: CNET Networks)

• We're not convinced about the wisdom of this one. GM is using this week's Frankfurt auto show to reiterate its commitment to alternative fuel cars with the unveiling of the Opel Flextreme, a concept plug-in car that builds on the buzz of the E-Flex drive train from the Chevy Volt. The car itself relies on a series hybrid drive train, which combines a lithium-ion powered-electric motor with a biodiesel combustion engine that is used solely for running the electric motor when the battery's charge runs out.

...or the past?

• However, as blue-sky as the vehicle's power train may be (lithium-ion batteries have a long way to go before they're ready for production vehicles), that is not the main cause of our concern. What troubles us is the fact that the GM has integrated two Segways into the back of the Flextreme--presumably to highlight its electric-mobility message. Now, we're no marketing mavens, but we suspect that a company trying to promote a fledgling technology would try to avoid association with a device that ended up falling--commercially and physically--flat on its face.

Photos: BMW Hydrogen 7

BMW rolled into town last night with a fleet of Hydrogen 7 sedans for us to test drive. Having already driven hydrogen cars from Honda and GM, we were intrigued to get behind the wheel of a hydrogen Bimmer, which differs from most other hydrogen-powered cars in that it doesn't rely on a fuel cell and electric drive train. Instead, it uses a modified version of the BMW 760Li's V-12 internal combustion engine to burn hydrogen in the cylinders in the same way as gasoline. It also differs from the pack in that that the hydrogen is stored in a liquid state rather than as a gas. Check out our gallery of the experience and more details on the car here.

BMW tops carbon-conscious list

Besides Toyota Motor and BMW, automakers haven't done a great job of building fleets that emit less carbon dioxide, according to an Environmental Defense report.

The organization's 80-page report, called "Automakers' Corporate Carbon Burdens" (PDF), evaluated the carbon dioxide emissions of vehicles from major automakers between 1990 and 2005. Companies graded were: Ford Motor, General Motors, DaimlerChrysler, Toyota, Honda Motor, Nissan Motor, Hyundai Motor, Kia Motors, Volkswagen, BMW, Subaru and Mitsubishi Motors.

"The rate of carbon dioxide emissions from new cars and light trucks in the U.S. dipped for the first time in two decades, but their overall contribution to global warming has continued to grow steadily since 1990," Environmental Defense said in a statement.

BMW achieved a 12 percent reduction in carbon dioxide emissions across its entire fleet of cars, more than any of the other car companies included in the study. Environmental Defense attributes the drop to the company's addition of the low carbon dioxide-emitting Mini Cooper to its lineup, as well as efficiency improvements made across its entire line of cars.

Toyota was rated the second best, reducing carbon dioxide emissions by 3 percent overall during that period, due in large part to its introduction of the Prius hybrid to its lineup and efficiency improvements made to the Corolla.

The report also rated the overall "carbon burden" that automakers placed on the environment, based on factors that included the emissions of their cars and the number of cars sold.

In this area, GM ...

Nissan Mixim concept

• It's showtime again in the auto world--that time of the year when manufacturers trot out their latest fleets of new models and wacky concepts. In preparation for the forthcoming Frankfurt auto show, Nissan this week unveiled details of its Mixim electric concept car. According to Nissan, the Mixim (which is unlikely to make it to production) is aimed at young, Web-savvy, digital-age drivers with a penchant for gaming. Check out our photo gallery here.
