Automatically efficient | 2017 Kia Optima Hybrid Quick Spin

Automakers are stuck between a rock and hard place with hybrid vehicles. On one hand, efficient hybrids are a necessary evil – for lack of a better phrase – to hit increasingly stringent CAFE standards. But on the other hand, low fuel prices mean it takes an increasingly long time for consumers to see a return on the investment of a hybrid's price premium. These factors have pushed automakers even harder to squeeze every mile per gallon possible out their hybrid offerings. That's inevitably led to powertrain innovations designed to maximize just how long and how far hybrids can run on pure electric power and how often the gas engine can shut down. Occasionally, this doesn't work out all that well – as is the case with the new Nissan Rogue Hybrid, for instance – but there are companies getting things right. Kia, with its 2017 Optima Hybrid, is one of them. Drive Notes Kia didn't try to get too creative with the Optima Hybrid's powertrain for 2017. There's a 2.0-liter, naturally aspirated, four-cylinder gas engine, a 38-kilowatt electric motor, and a 1.62-kWh battery pack. Total system output is 192 horsepower and 271 pound-feet of torque, with EPA estimated fuel economy ratings of 39 miles per gallon in the city and 46 mpg on the highway for a 42-mpg combined rating. That's all spiffy. But taking a six-speed automatic and replacing the torque converter with a clutch and the electric motor, Kia built a hybrid sedan that smoothly intertwines disparate power sources as well as a conventional hybrid like a Toyota Prius, while allowing the Optima Hybrid to take greater advantage of zero-emissions systems. Lift off the throttle and the four-cylinder engine shuts down and lets the 50-hp electric motor handle light, constant-throttle cruising below 62 miles per hour. Dig deeper into the gas, and the petrol powerplant quickly restarts and delivers the bulk of the Optima's power for heavy acceleration and higher-speed conditions. The Optima's back and forth is rarely disjointed – Kia's hybrid feels a lot like its conventionally powered model in normal driving. It's only under sudden, wide-open throttle situations, where the hybrid systems feel caught off guard, that the Optima Hybrid feels flatfooted. A less obvious benefit of the six-speed automatic, of course, is that it leads to quieter operation. There's no rubber-band-like revving like you'd get with a CVT because the transmission can actually shift up a gear.

Kia recalls 9,700 new Sorento models for potential front axle failures

Kia has announced a recall on the 2014 Sorento due to an issue that could lead to a broken right front driveshaft on certain models. Only models equipped with the 2.4-liter inline four-cylinder engine and front-wheel drive are affected by the campaign.
The National Highway Traffic Safety Administration says that Sorento models built between January 7 through March 12 of this year may experience broken axle shafts that could lead to loss of power or cause the vehicle to roll if parked. According to the Detroit Free Press, a total of close to 9,700 units are being recalled, but that number is closer to 9,300 for customers in the US.
Kia says that it has had one incident with an internal vehicle that experienced a separated axle shaft in addition to 10 related warranty claims, but it says no accidents or injuries have been reported. The recall campaign will begin next month. Scroll down for the NHTSA recall notice as well as an official statement from Kia.

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.'
