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.

5 Hyundai and Kia models have higher-than-average fire insurance claim rates

DETROIT — Owners of five Hyundai and Kia cars and SUVs file fire insurance claims at a rate far higher than the average for comparable vehicles, according to an insurance industry study. The Highway Loss Data Institute, which analyzes data from insurers representing about 85 percent of the U.S. industry, found that some Hyundai and Kia vehicles equipped with four-cylinder engines have double the noncrash fire claim rates than the average of comparable vehicles. Last week the South Korean brands announced they would recall about 168,000 vehicles to fix a fuel pipe problem that can cause fires. The problem stems from improper repairs during previous recalls for engine failures. They also announced additional sensor software for another 3.7 million vehicles. Hyundai and Kia started recalling 1.7 million vehicles in 2015 — about 618,000 of which are Kias — because manufacturing debris can restrict oil flow to connecting rod bearings. That can cause bearings in 2-liter and 2.4-liter four-cylinder engines to wear and fail. The problem can also cause fires. The repair in many cases is an expensive engine block replacement. Results of the Arlington, Virginia-based institute's study have been turned over the U.S. National Highway Traffic Safety Administration, which is investigating engine failures and fires in Hyundai and Kia vehicles. The agency is mostly closed this week due to the partial government shutdown. Hyundai said Tuesday that the majority of its models in the study are already being recalled or are part of additional actions to keep customers safe. "Hyundai actively monitors and evaluates potential safety concerns, including non-collision fires, with all of its vehicles and acts swiftly to recall any vehicles with safety-related defects," spokesman Michael Stewart said. Kia spokesman James Bell said the company is cooperating with NHTSA "and will take any necessary corrective action in a timely manner." Many of the fires involve vehicles included the engine failure recall and could have been prevented if owners had the recall repairs done, he wrote. The institute began studying fire claims after the Center for Auto Safety petitioned NHTSA last year seeking a wider recall of Hyundai and Kia vehicles. The center had found a higher-than-normal number of consumer complaints about Hyundai and Kia fires in the agency's database. NHTSA has used Highway Loss Data Institute studies in the past to help make recall decisions.

Hyundai, Kia, Genesis will get chip maker NVIDIA's infotainment in deal

Chip maker NVIDIA Corp on Monday announced that Hyundai Motor Group will use the NVIDIA DRIVE in-vehicle information and entertainment system for all its Hyundai, Kia, and Genesis models from 2022. NVIDIA said the luxury vehicle division of Hyundai, Genesis, already uses NVIDIA DRIVE for its GV80 and G80 models. (You can read a bit about the Genesis infotainment systems in Autoblog's recent driving reviews of the G80 sedan and the GV80 SUV, and our buying guide for the latter.)  NVIDIA declined to say how many vehicles NVIDIA DRIVE would be installed in, but said it is a large number and pointed to the fact that in 2019 Hyundai Motor Group shipped over 7 million vehicles. Hyundai Motor Co is the flagship company of Hyundai Motor Group, and Kia Motors Corp is its sister company. NVIDIA DRIVE includes hardware and software components and uses artificial intelligence to improve the user's experience. The software can be "perpetually" updated, giving vehicles the latest AI cockpit features, said NVIDIA. NVIDIA said it has also been working with Mercedes-Benz, Audi and Honda on in-car entertainment and information systems. Related Video:
