Why aren’t we seeing diesel/electric hybrid cars and light duty trucks? Wouldn’t the fuel economy be phenomenal? Gas hybrids do well in their own right, as do diesels. So what’s holding up the diesel/electric Passat? Many cities have gone to diesel/electric buses for fuel savings, so we know the technology is real for passenger vehicles. Is the combined torque simply too much for mere mortals to use responsibly?
What gives, Sajeev?
The next-generation Smart Fortwo, expected to go on sale in North America shortly, won’t achieve the magical 40-mpg benchmark in highway driving, reports Car & Driver.
Fuel economy for the Mercedes microcar will stay similar to the current generation at 33 mpg city and 39 mpg highway when equipped with the automatic transmission. Manual models will get the same highway fuel economy, but give up 1 mpg on the city cycle.
Volkswagen’s Golf TDI traveled more than 8,200 miles around the lower 48 states on less than $300 of diesel in 16 days, the automaker said today.
The 16-day trip around the U.S. set a
narrowly-defined world record for “lowest fuel consumption — 48 U.S. contiguous States non-hybrid car” by averaging 81.17 mpg in the Golf TDI. The car was driven by automotive journalist Wayne Gerdes and electronics engineer Bob Winger.
Quick math: If the duo averaged 15 hours of driving per day, the pair managed an average speed of 34.306 mph throughout the entire journey.
After a series of scandals involving incorrect fuel economy ratings, the EPA is revising its self-reporting guidelines for auto maker fuel economy standards, in a bid to ensure greater accuracy in the real world.
Chrysler has been on a steady upswing since the dark days of bankruptcy. Throughout its merger with Fiat, each model has been updated or completely replaced. Jeep has been the shining star of the core brands, selling every Grand Cherokee and Wrangler they can make. Even the controversially styled Cherokee has been fairly well receieved. The next vehicle in the Jeep lineup will be the small Renegade, designed to attract “a new wave of youthful and adventurous customers around the world to the brand.” We concur.

The car I am writing about today is my winter beater, which is a 1999 Ford Escort SE sedan which says it has a tick over 155,000 miles. (Pictured above) The problem I’m having with it is it it getting dreadful gas mileage. My average tank is about 19 miles to the gallon (in comparison that is what my twin turbo straight six Volvo gets around town). Over the winter I replaced both of the o2 sensors and got a marginal improvement (about .4 mpg).
And here’s the kicker: the dumb thing runs perfectly. No error codes or anything. Idles smooth and everything (well as far as Escort refinement goes). When I go on the highway (which is fairly often) I can see upward of 21… If I’m lucky. (Read More…)
In light of re-estimated mileage per gallon claims by Ford, Hyundai and Kia, the Environmental Protection Agency seeks to prove the claims of all automakers through real-world testings.
Truck Mountain may still be held by the soon-to-be-lightened Ford F-150, but the fuel-efficiency battle in the valley below is already underway, thanks to Ram’s 1500 EcoDiesel pulling the highest mile-per-gallon highway rating of any light truck in the United States at 28 mpg.
The revised fuel economy ratings for the Ford C-Max aren’t the first time that an auto maker has been forced to backtrack on fuel economy claims – nor will it be the last unless meaningful reform is undertaken to ensure that fuel economy figures more accurately reflect the way motorists drive their cars in the real world.
Fuel economy of vehicles sold in the U.S. is on the rise, recording the sharpest gains in almost four decades, an annual report by the EPA shows. Foreign automakers have the most efficient fleets.
The EPA report shows an average 16 percent gain in fuel efficiency for in the past five years, to 23.8 miles per gallon. The EPA’s list is led by foreign carmakers, with Detroit sharing the bottom places with purveyors of thirsty performance cars. (Read More…)
