2013 Hyundai Sonata Hybrid gets bigger, better battery pack, lower MSRP

Just yesterday, we told you how Hyundai's 2013 Sonata Hybrid was late out of the gate (along with its mechanical twin, the Kia Optima Hybrid), with growing speculation suggesting that the company was revisiting its gas-electric sedan with an eye toward improving its efficiency.
Well, today Hyundai has released official details, and that's exactly what's happened. Sporting a larger starter generator, a higher output electric motor and a more potent 47 kW lithium polymer battery, the 2013 Sonata hybrid is more efficient than before. The revised hardware helps the sedan jump two miles per gallon combined over its 2012 predecessor. That pushes the 2013 Sonata Hybrid to 36 mpg city, 40 mpg highway and 38 mpg combined. Engineers also tweaked the machine's software, with revised driving pattern detection and engine on/off logic.

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.

Hyundai, Kia want to improve fuel economy by 25 percent

Hyundai and sister company Kia are giving themselves a little bit of time to make up a lot of ground in the fight for better fuel economy. We wonder if a recent multi-million fine might have something to do with this public target. The connected South Korean companies are vowing to increase their fleetwide fuel economy by 25 percent by 2020, Reuters reports. This will be done by further advancing their powertrains, looking at other ways to reduce weight, upgrading diesel engines and improving transmissions. That will all take money, but Kia and Hyundai will have $300 million less to invest thanks to a recent fine of more than $300 million from the US Environmental Protection Agency (EPA), the Department of Justice and the California Air Resources Board (CARB) for incorrect fuel economy numbers on around 1.2 million vehicles from the 2011-2013 model years. The civil penalties – $100 million of the total – are the largest in EPA history. In late 2012, Hyundai and Kia admitted to overstating the fuel economy of a number of models and said they'd change the official MPG figures and compensate owners. Hyundai spokesman Chris Hosford confirmed to AutoblogGreen that the company set the dramatic fuel-economy improvement targets. In the US, where Hyundai and Kia are operated as separate entities, Hyundai "remains committed to meeting the CAFE (Corporate Average Fuel Economy) requirements that have been set out by the US government," Hosford said The EPA recently released a report on fuel-economy and put Hyundai fourth in overall fleetwide fuel economy in the US among vehicle makers for the 2014 model year. The top three were Mazda, Honda and Subaru.
