World's First Affordable Diesel Hybrid Powertrain
When the vehicle pulls away, torque is delivered only from the electric traction motor. As speed increases, electric and diesel drive blend seamlessly until torque from the electric drive is reduced to zero.
Okay this is a business Journal so I'm sorta skeptical. Although the article goes quite into a bit more detail than I expected. The quote is on page 2 of a 4 page deal. Actually quite a bit of detail starts on page 2. I don't know how they get away from propriety as it sounds just like what a Prius does (43kW DC starter/generator, 50kW AC Traction motor) [Engineers please explain why not all DC or all AC?) Also near the end it mentions it's also Plugin to boot (Lion batteries too) so it's a Diesel/Hybrid/Plugin car.

They use 'clutch-less' shifting, a very neat trick! This means you can use an ordinary, light weight, manual transmission and shift from gear-to-gear without a clutch. This is a very good solution that beats both CVT and eCVT in efficiency. What is especially important is use of the traction motor to avoid any clutch. . . . very clever!
If I read the article correctly, the traction motor solves the problem of starting from a 'dead stop.' BTW, this system will work with non-diesel engines too.

Re: World's First Affordable Diesel Hybrid Powertrain
Sounds very promising.
On a related subject, I still can't figure out why New York State won't allow the sale of diesel cars, when there are no restrictions on the sale of diesel pickup trucks.
That is all the more ironic, since Corning, Inc. is now building and expanding a plant to manufacture catalytic converters not only for medium and large diesel engines, but also for diesel cars:
