Not at all unlike the GM E-Flex platform in concept, shown first under the Chevrolet Volt and in Frankfurt under the Opel Flextreme, the Volvo Recharge at the 2007 Frankfurt show used a lithium-ion battery pack to power individual electric wheel motors. (Follow this link to see Volvo’s press conference.) The internal combustion engine on board is used for backup and battery recharging only, and has no part in moving the vehicle. The Recharge was designed for plug-in application, with Volvo estimating about three hours for a full charge. Volvo estimated the electric-only range to be about 62 miles, leading the company to note that Recharge would be best suited for those with daily round-trip commutes below that distance. While GM has shown its E-Flex platform with concept-car bodies above, Volvo put their new C30 on top of the Recharge platform.
I spent two days crisscrossing the massive Frankfurt auto show, and the focus on reducing emissions and improving fuel economy and “green” solutions could not be missed. Very few manufacturers were not talking about fuel economy gains in their powertrain lineup and many announced hybrid plans or showed hybrid concepts. What we’re seeing here is the culmination of years of research, rather than fiberglass what-if models. Many of these hybrids or other technology-based solutions will be on the roads later this decade.
Mercedes-Benz will, during the 2009CY, offer a hybrid powertrain in the S-Class and the M-Class, while a smart fortwo mild hybrid system goes on sale in October. Porsche gave updated the Cayenne’s diesel for more power but also promises a parallel series hybrid using the existing 3.6L V6 by the end of 2010CY. General Motors took the system shown under the Chevrolet Volt in January, replaced the gasoline engine with a diesel one, and created the Opel Flextreme as well as showing off an Opel Corsa Hybrid. Volvo put a plug-in hybrid into the C30 to create the Recharge concept. Land Rover is adding stop-start systems in 2009CY, and Audi will bring a hybrid to the Q7.
Small cars are more prevalent on international roads and therefore more prevalent at auto shows outside the United States. Toyota brought us the iQ, Volkswagen the up!, and Ford the Verve. Renault’s latest Twingo was on the show floor as well, though this was not its debut.
Notable exceptions to the small and green game were Ferrari and the 430 Scuderia (introduced by Michael Schumacher himself), the Aston Martin DBS (officially introduced at the 2007 Pebble Beach Concours d’Elegance), the Bentley Continental GTS Speed, the Lamborghini Reventon (of which only twenty will be made, with a price tag around $1.4 million), and Maserati.
Day two of Frankfurt’s show holds most of the supplier press conferences, leaving us a chance to take photos and see some general reaction. Frankfurt’s convention center has 10 halls, with at least seven of them holding the major manufacturers and others holding aftermarket and supplier stands. Walking the full show requires much time and comfortable shows and several hours. Interest was strong in the Mercedes-Benz F700 Concept (previewing the next S-Class), the Audi A4, Opel’s Flextreme, Ford’s Verve and Kuga, and Jaguar’s XF. Peugeot and Citroen concepts, the 308RCZ and the Airscape, saw plenty of attention, as did Nissan’s very odd-looking Mixim.
The Volkswagen Tiguan stand was flocked with people getting a chance to get in and crawl around the new model, with plenty also checking out the up! city car. Interestingly, every time I went through hall 6, home to Italian makes Alfa Romeo, Fiat, Lancia, Ferrari, and Maserati as well as Porsche and Hyundai it was completely mobbed. On the other hand, Kia’s Kee coupe concept and BMW’s X6 concepts didn’t seem to grab attendees as much.
While going green may be good for us, hybrid systems and new engine developments don’t make for great pictures or put the enthusiasm into driving that a great-looking design can. Over the coming weeks, we’ll bring you more detailed coverage of many of these. Stay tuned.
