The E-Flex platform with European style and a diesel is only a dream here in the US. (http://www.detnews.com/apps/pbcs.dll/article?AID=/20070911/AUTO04/709110341/1148/AUTO01)

The Opel Flextreme PHEV concept uses a diesel engine as the range extender and an all-electric drive with a range of 34 miles for everything else.

FRANKFURT, Germany -- The night before the environmentally focused Frankfurt auto show, General Motors Corp. laid out its green credentials with the unveiling of the Opel Flextreme.

As the latest version of GM's electrically driven E-Flex vehicle architecture, the Flextreme concept follows on the heels of the hit Chevrolet Volt concept.

The new concept differs from the Volt in its body design and use of a small diesel engine generator, or range extender, to charge the lithium-ion battery pack. Diesel engines account for more than 50 percent of sales in some European markets.

The Volt has a gasoline-fueled generator, while a third version of the E-Flex, revealed recently in China, uses a hydrogen fuel cell as its on-board energy source.

At the Frankfurt preview, Bob Lutz, GM vice chairman of global product development, highlighted the Flextreme's 55 km (34-mile) battery range.

"As 75 percent of Europeans commute less than 55 kilometers a day, the vehicle could effectively be emissions-free," Lutz said. Even when the 1.3-liter turbo diesel motor kicks in to charge the battery, the powertrain's emissions are predicted to be less than 40 grams of carbon dioxide per kilometer, which is a third of the standard the European Union is considering for passenger vehicles in 2012 … http://www.detnews.com/apps/pbcs.dll/article?AID=/20070911/AUTO04/709110341/1148/AUTO01

Makes me wonder what its diesel mileage is if it can only go 450 miles on a tank of diesel (given its total range of 480 miles on electric plus diesel). Either it has a very small fuel tank or it is is getting poor mileage on diesel.

Hi Basjoos:

___Having driven the iCDTi for a week, I have to believe the Flextreme’s FE numbers are vastly under-reported?

___Good Luck

Unless Honda has some serious magic in their engine that no one else has? I've never heard much from the VW TDI drivers other than mid to high 50's, IIRC?

In this case I think the Honda's serious magic is in the nut that's holding the steering wheel.:D

That's hitting the nail on the head, the driver makes a huge difference. This guy was making news a couple years ago, the TDI is capable of some good numbers if driven correctly.

I stand pleasantly corrected! I'd still take the Honda over a VW, though. ;)

Hi Sefton:

___Thank god for the TDI owners as they have been driving for great FE for years! This 2.2L iCDTi appears to have the 1.9L TDI beat in terms of FE, performance, NVH and drivability for whatever reasons? My friends 04 Jetta TDI is missing so much by comparison but I am holding out hope for the upcoming 08 TDI’s to begin a new era for VW.

___Good Luck

The i-CTDi's common-rail injection helps a lot in pretty much all those areas. Common rail injection allows for much more precise control over injection timing and events than VW's unit injectors. The 1.9 TDI is also 15 years old and has a high compression ratio which means more noise and vibration - 19.5:1 vs around 16.7:1 for the Honda if I remember correctly.
