This is a follow on from my previous post on over-powered hybrid transit buses. ***************
"engine and a hybrid transmission consisting of two 100 kW motors and a 600-volt, nickel metal hydride battery pack. The engine is coupled to an electronically variable transmission that provides an infinite range of gear ratios to drive the wheels."
After some digging I found that Cummins engines in the 250-280Hp are the prime movers for the above. And a max service speed of 65mph was quoted.

Elsewhere someone provided these links regarding the iconic London Transport double decker bus. tfl= transport for London

The release didn't state the manufacturer of the 1.9L diesel engine that powers this vehicle. The vehicle itself was built by WrightBus Limited. No indication was given either whether this was in fact a government funded project along the lines suggested by those researchers, that government funding be awarded only for designs with a 90Kw power ceiling.
In the light of what WrightBus have achieved it's hard to see why Allison would need 210Kw for their vehicle. But if I was running GM I would be asking questions.

#391 of 395 PHEV diesel !! Cool !! Go DC !! by larsb

Good Job DC !!! KUDOS !!!The Dodge Sprinter PHEV has the ability to drive up to 20 miles on electric-only power. It accomplishes this with a switch on the dashboard giving the operator the ability to manually switch between modes as needed, or automatically by the vehicle control system. Two different combustion engines are being offered in the Dodge Sprinter PHEV -- diesel or asoline. The diesel version will yield the highest fuel economy benefit and is the first fleet test of a diesel plug-in hybrid system.

Because there is no currently available SUV with a Hybrid-Diesel I purchased a 2008 Mercury Mariner Hybrid-Atkinson. The Atkinson cycle really is quite good--it has nearly complete expansion as opposed to the Otto cycle, which does not. On the 2008 EPA ratings, the 4WD Mariner (and its sibling Escape) is supposed to get 29 mpg city, 27 mpg highway, 28 mgp combined. Mine is not, of course, broken in yet, but I got 26 mpg on the first fillup, 24.5 on the second, and currently am getting 27.7. We'll see in a few thousand miles...I'm hoping to achieve 30 mpg!#393 of 395 Long Trip Fuel Economy by transpower

I recently had to drive to Southfield, Michigan from Trevose, Pennsylvania, and back--a total of over 1200 miles. In my 2008 Mercury Mariner Atkinson-Hybrid I got 31 mpg going West and 32 mpg going East, the difference probably being due to the difference in wind direction. So I easily made my goal of 30 mpg or better!#394 of 395 A-B-O-U-T D-A-N-G T-I-M-E !!!!!!!!!!!! by larsb

Diesel plus hybrid equals 70+mpglink title
The latest diesel-powered cars offered in Europe come close to - and in a lot of cases beat - hybrid-electric cars like Toyota's Prius in the mileage stakes, so imagine what would happen if you combined the best of both technologies. France's Peugeot hopes to do just that and by becoming the first carmaker to launch a diesel-electric hybrid by the end of the decade.
The recently launched midsize Peugeot 308 hatch will be the first vehicle fitted with the new powertrain, but it's likely other models will soon follow suit if it proves to be successful.
The Peugeot diesel hybrid should average better than 70mpg (58.3mpg US), which would mean its emissions levels would be lower than most other cars except for pure electric vehicles. By comparison, the Prius rates 65.7mpg (54.7mpg US). However, most motoring mags have found its real-world fuel economy ratings to be much lower.
The only factor holding back the release of the hybrid 308 is the high cost of the batteries and electric motor, but engineers are working hard to make the technology more affordable.

Smoking hot diesel hybrid for sale in 2010Now they have it testing at 80 MPG on the Euro circuit, or about 67 MPG USA.
Of course the lucky Europeans will get it first GRRRRRRRRRR !!!
