Gap in fuel efficiency and torque between diesel and gasoline engines is dwindling

Diesel engines are very popular around the world, and are used in both passenger and commercial vehicles due to their efficiency advantages over gasoline engines. In the U.S. passenger vehicle market, they’re largely relegated to heavy-duty pickup trucks (although companies like Volkswagen have maintained a diesel engine lineup for a few decades). 
However, diesel fuel averages roughly $0.36 a gallon more than regular unleaded gasoline in the U.S., which can erase some of the cost advantage.

While many diesel-powered vehicles do have better fuel economy than comparable gasoline vehicles, even that benefit is beginning to disappear. In spite of this, many automakers are preparing to launch diesel-powered cars in the U.S., including GM, Chrysler, and Mazda.

Detroit News reports that diesel engines in cars no longer have a major advantage in torque and they don't offer significantly better fuel economy. Technology for traditional gasoline engines is improving and the gap in fuel efficiency and torque has vanished due to the proliferation of direct injection and turbocharging.

With this in mind, Ford, Toyota, and Hyundai are staying out of the diesel-powered car market; instead focusing hybrid technology. Hyundai Motor America CEO John Krafcik says that the cost of adding hybrid technology for the consumers about $1,500 compared to a cost of about $5,000 to add diesel power.
"When we ask if consumers are willing to pay that, they ask, 'What are you smoking?'" said Krafcik. "We all have great diesel engines available to us, but gasoline engines are growing."
However, Ford says that it is ready to begin offering diesel-powered cars in the U.S. if there is enough consumer demand

Uh say what? A $10,000 battery and $5,000 to 15,000 worth of additional electronics only costs the people $1500 more?

I know finding a single vehicle line that has diesel, gas, and hybrid technology is tough. But one such line is the 2013 VW Jetta.

Average prices within 200 miles of me (north FL):
Gas $25,000 ($23 to 30K depending on options)
Hybrid SEL $30,000 ($29 to 31K depending on options)
Diesel TDI $26,000 ($24 to 28K depending on options)

Looking at the fully loaded high end of all 3 variations, they all run around $31,000 at most. The base least number of option models range from $23K for gas, $24K for diesel, and $29K for hybrid (due to fewer "option variations" available on the hybrid line).

Average price shows that vehicles with Diesel engines is on par with gasoline vehicle prices, yet hybrids, even after a $1500 subsidy rebate from the government still averages quite a bit higher than the others.

Even in full size trucks (most of which do not have hybrid versions available), the only real reason for the $5,000 price increase for diesels is the higher end diesel engine (Cummins, Power Stroke, etc). The truck models that have a comparable smaller V8 or even inline 6 diesel engines run the same comparable price ranges to gasoline version as the Jetta shown above.

So really this guy was just making false claims to push their falsified "green" agenda.

Here in England we've been running common-rail injection diesels in passenger cars for about 10 years.

I've had 2 Diesel Ford Focus - but like a lot of drivers, I'm switching BACK to petrol - or more accurately hybrid Toyota.


Here are the bills you'll get running your diesel car anything over 3 years and 30,000 miles - from

And I have had ALL these problems in 2 cars - this is not some 'internet theory'!!

Dual mass flywheel failures on manuals leading to failures of drive, often incorrectly prescribed as clutch failure when in fact it is the dual mass flywheel that has failed: £800 - £1,500.

Turbo and intercooler failures: £1,000 - 1,500.

EGR failures: £300

Manifold swirl chamber failures: £300 +

Injection pump failures £1,000 - £2,000

Injector failures £250 - £1,500

Diesel particulate filter failures £500 - £1,500

Glowplug failures up to £1,000 if they come out. Up to £3,000 if they snap and the head has to be removed to extract them.
