EPA says it will more closely monitor fuel economy claims from automakers

The unintended acceleration brouhaha at Toyota led to the National Highway Transportation Safety Administration tightening the vise on recall procedures. Likewise, the fuel economy kerfuffle that blew up with Hyundai and Kia's admission of overstated fuel mileage claims could lead to the Environmental Protection Agency policing automaker assertions by performing more audits.
At least, that's what a senior engineer with the government agency said while in Michigan giving a talk, according to a report in Automotive News. What that actually means, however, is still in question. Just ten to 15 percent of new vehicles - something like 150 to 200 cars per year - are rested by the EPA to verify automaker numbers. The EPA's own tests include a "fudge factor" to adjust lab mileage for real-world mileage, and the agency still relies on automakers to submit data for tests that it doesn't have the facilities to perform. How much more auditing can the EPA really expect to do, or perhaps a more relevant question would be how much more accurate could the EPA's audits become?
The price of gasoline, the psychological importance of 40 miles per gallon to a frugal car buyer, an automaker wanting to further justify the price premium of a hybrid, all of these things contribute to fuel economy numbers that insist on creeping upward. Perhaps the senior engineer encapsulated the whole situation best when he said, "Everybody wants a label that tells you exactly what you're going to get, but obviously that's not possible. A good general rule of thumb is that real-world fuel economy is about 20 percent lower than the lab numbers." If the lesson isn't exactly 'buyer beware,' it's at least 'buyer be wary.'

Kia showcasing Optima T-Hybrid concept in Paris [w/video]

At the Geneva Motor Show earlier this year, Kia showcased a new diesel hybrid powertrain. And at the rapidly approaching Paris Motor Show, it will present that new technology in the Optima sedan concept you see here.
Called the Kia Optima T-Hybrid, the concept mates a 1.7-liter diesel with both a turbocharger and electric supercharger to a small electric motor and a 48-volt lead-carbon battery. The mild hybrid setup allows it to travel in electric-only model at low speeds and at cruise, regenerating brake power to recharge the battery. Kia said it chose the lead-carbon battery pack over lithium-ion because it's easier to recycle and does not require active cooling.
Because the powertrain is still under development, Kia isn't saying what kind of fuel economy or emissions figures it gets in the Optima T-Hybrid concept, but it is targeting a "significant reduction" in emissions and fuel consumption, while delivering 15 to 20 percent more power. Check out the system in action in the video below.

Hyundai-Kia fuel-economy errors trigger $300M in federal penalties [w/video]

This amount includes $100-million in civil penalties, the largest such fines in EPA history.
Hyundai and Kia are getting more than a slap on the wrist for overstating the fuel economy of an estimated 1.2-million vehicles in their 2011-2013 model ranges. The Environmental Protection Agency, the Department of Justice and the California Air Resources Board are hitting the automakers with collective penalties valued at around $300 million for Clean Air Act violations. This amount includes $100-million in civil penalties, the largest such fines in EPA history. Specifically, Hyundai is paying a $56.8 million penalty and relinquishing 2.7-million greenhouse gas emissions credits. Kia is paying $43.2 million in penalties and giving up 2.05-million credits.
