Honda looks to conquer all rivals with the Accord Hybrid

We reported in June that Honda was forecasting fuel economy numbers of 49/45/47 (city/highway/combined) for its upcoming 2014 Accord Hybrid. Well, it turns out that after further testing, the city number has been nudged up just a tad to an even 50 mpg according to TOV.
Even with the 50 mpg city rating, the vehicle will still have a combined fuel efficiency rating of 47 mpg, which is impressive in its own right. The Accord Hybrid easily beats the ratings of the other midsize hybrids and diesels on the market, and matches the combined rating of the Ford Fusion Hybrid (although the Fusion Hybrid, like its disgraced C-Max sibling, has encountered trouble meeting its EPA numbers).

The Accord Hybrid uses a 2.0-liter gasoline engine (141 hp), 124 kW electric motor, and a lithium-ion battery pack. The on-sale date for the vehicle is scheduled for October of this year.

The problem with diesel engines, and the reason you don't see diesel hybrids, is because they can't run a miller-cycle combustion system like a petroleum engine. This would require a complete rework of how hybrid drive trains are developed. Currently, the electric motor acts as a starter, recovery, and propulsion motor. Diesels don't exactly start smoothly and like continuous service, not constant stop-starts (although UPS has implemented a creative workaround to this for their delivery trucks.)

The best current diesel hybrid implementations are using the diesel engine to generate electricity and run electric motors (think Fiskar Karma/Chevy Volt, but with a hybrid). This hybrid system has been around for over 100 years, it started in locomotives, and has since transitioned to marine applications, buses, and short-distance trucks.

Then you need to consider the added costs of a diesel, cold-weather performance (although the hybrid batteries could be used to power a block warmer when temps drop too low) maintenance (especially the stupid urea tanks now) and varying quality of fuel which affect all sorts of things (NVH, performance, efficiency, fuel system)

All good points, although fuel quality varies with gasoline, too -- particularly when it comes to how much, if any, ethanol is added to it.

The NY Post is saying maintenance on hybrid buses is such a problem that they're planning to retrofit buses with diesel engines.

Wow, someone better tell Citroen about this not being feasible,

How sad is it the French are leading the way in the holy grail of hybrids.

Dude did you even read that article? They complain about the very things I mentioned are hurdles with diesel hybrid technology, specifically judder during power plant transition, unexciting drivability and marginally better fuel economy than a base diesel.
