#40MPG

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.

The current Buick Regal is an excellent car. I know, because I have one parked in my garage (it’s sweet). Still, it could be better- and the guys at the SouthWest Research Institute (SWRI) have figured out a way to enhance the mid-range Buick so that it produces fewer harmful carbon emissions and gets better fuel economy.

Can’t beat that!

TTAC’s inbox was inundated this morning with reports of Hyundai’s revised mileage claims, which remove a number of its vehicles from the 40 MPG club.

According to Hyundai

Procedural errors at the automakers’ joint testing operations in Korea led to incorrect fuel economy ratings for select vehicle lines.

Maybe it’s time for a new way to measure fuel economy standards?

It’s the kind of mistake that only a blogger (said with a contemptuous sneer) would make. The Wall Street Journal reports that

“U.S. regulators rated a new Chrysler Group LLC compact car with highway fuel-economy of 41 miles a gallon, a move that fulfills a key element of the company’s 2009 federal bailout and cleared the way earlier this year for majority owner Fiat SpA to increase its stake in the Detroit auto maker.”

They got it wrong.

A couple tweaks have finally pushed the Fiat 500 to the magical 40 MPG mark – but only on manual-equipped version.

I saw the future as clearly as day.

The Honda CR-Z. A beautiful machine that would finally marry that elusive dream couple, sport and fuel economy, for less than $20,000.

It had to be a hit. Just had to…

Glancing at its diminutive footprint and tiny engine specs, one would expect superlative fuel economy from the Chevrolet Spark, right? Wrong.

Looks like the Dodge Dart will apparently break 40 MPG adjusted in the end…but you’ll need a special option package to do it, just like its chief domestic rivals, the Ford Focus and Chevrolet Cruze.

Sometimes the stars align. Last week’s article about the “Consumer Watchdog” Elantra fuel-economy press release had ruffled some feathers and aroused my personal curiosity regarding the Elantra’s alleged thirst. And then — wouldn’t you know it — I found myself with a chance to run South and visit a few friends. The time frame was short. Had to be there and back in 36 hours, covering about 435 miles each way. And the nice people at Enterprise were willing to rent me a 2011 Elantra for a two-day stretch at a total of $50.36.

This was my math: (900 miles/23.5 mpg) * $3.18 = $121.78. That would be the cost of running my Town Car. A mythical 40mpg Elantra plugged into the same equation would cost $71.55. Difference of $50.23. Clearly some sort of sign, right? Might as well rent the Hyundai and conduct a highly non-scientific test. Along the way, we’d ask the usual questions: How well does the Elantra hold up in rental service? Is this the class killer some people want it to be, or the mid-packer described in TTAC tests up to this point? Can’t this thing go any faster? What time is lunch?

There was troubling news at the end of last week, as Automotive News [sub]’s Rick Kranz reported that an unnamed automaker was quietly accusing another unnamed automaker of tweaking its EPA fuel economy tests, arguing

There’s a noticeable difference between the mpg number posted on some cars’ window sticker and an analysis of the data submitted by automakers to the EPA.

We’ve tried to get several automakers to comment on the accusation, but nobody wants to touch it. But, as we’ve looked into the issue, a few more details have surfaced that seem worth sharing. Hit the jump for the latest…
