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.

Hyundai developing safety system calibrated for 'secondary impacts'

There is an inherent flaw with how traditional airbags are used and deployed: They can only reply to one impact. The Hyundai Motor Group wants to address this with a new "multi-collision airbag system" that focuses on impacts that occur after the first point of contact. Hyundai defines multi-collision accidents as "those in which the primary impact is followed by collisions with secondary objects, such as trees, electrical posts or other vehicles." In a press release, Hyundai noted that about 30 percent of roughly 56,000 accidents between 2000 and 2012 in North America involved these types of multi-collisions, according to the National Highway Traffic Safety Administration (NHTSA)'s National Automotive Sampling System Crashworthiness Data System division. The airbag systems in today's cars don't always go off when the first accident occurs, and when a car goes through a secondary impact, the airbags may no longer provide the best safety. Hyundai's new system can read the positions of the car's occupants and react in a more beneficial way. It can quickly recalibrate after the first impact based on readings from the vehicle and the people inside, which allows the second part of the crash to trigger the airbags. As of now the system is still in development, but Hyundai Motor Group is planning to use it in both Kia and Hyundai vehicles in the future. Which models and which markets it will apply to first are yet to be determined. Related Video:

Small 3-row crossover SUVs specifications compared on paper

There's no shortage of three-row vehicles on the market for carrying seven or more people and their stuff wherever they all need to go. Just about every car company has at least one large crossover or traditional SUV with three rows of seats, and there are still plenty of minivans to pick from. But most of these vehicles are large, pricey, and frequently thirsty. Fortunately, there are still a handful of smaller crossovers that deliver 7-passenger capability in a smaller, cheaper package. We've gathered four of the small three-row set here to compare them based on space, power, fuel economy, pricing, and more. They include the very old Dodge Journey, the slightly less old Mitsubishi Outlander and Kia Sorento, and the relatively new Volkswagen Tiguan. You can see the raw numbers in the chart below, followed by a more detailed breakdown and some notes on how we like each of these vehicles. For in-depth opinions on the vehicles, be sure to check out our full reviews, and if you want to compare these with other vehicles, try out our comparison tools. Engines, transmissions and performance Interestingly, three of the four crossovers here utilize similar engines for their four-cylinder offerings. The Dodge, Kia and Mitsubishi all feature naturally aspirated 2.4-liter four-cylinder engines. Only the Volkswagen Tiguan chooses turbocharging and a smaller 2.0-liter displacement. But because of its turbocharger, the Tiguan's four-cylinder is easily the most potent, making a healthy 221 pound-feet of torque, which is more than 40 more than the Sorento, the crossover with the next most torque. The VW is also second-most powerful, just one horse behind the Sorento. The Outlander is the least powerful in the four-cylinder class. The Journey is only barely better, but it will probably feel as slow or worse thanks to its ancient 4-speed automatic. The four-cylinder Sorento and Outlander each have 6-speed automatic transmissions, and the VW has an 8-speed. The Sorento with a V6 has an 8-speed, too. View 17 Photos Moving up to the V6 class, the Outlander is once again at the bottom. It actually makes less torque than the turbo VW Tiguan. The Journey and Sorento are almost perfectly matched. The Journey makes a bit more torque; the Sorento makes a bit more power. The Journey also gets upgraded to a 6-speed automatic. Another powertrain consideration to bare in mind is whether all-wheel-drive is necessary.
