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.

Almost Jeffersonian | 2017 Kia Optima Plug-In Hybrid Second Drive

On a drive of Kia's new Optima Plug-In Hybrid (in showrooms since April), we visited Thomas Jefferson's Monticello, our third president's sprawling estate in central Virginia. Even in the absence of Twitter, Jefferson enjoyed a restless curiosity about an array of subjects. While his day gigs – declaring independence and consummating the Louisiana Purchase – occupied much of his life, he always made time for intellectual pursuits and making daily life better, so we think he'd grasp the rightness of the Optima. In the science of the plug-in hybrid, there's little new. The combination of gas and electric motors is intended to reduce the carbon footprint of a conventional drivetrain. Add a motor, install more battery capacity and enable that battery to be recharged over a long lunch or overnight, and you have a plug-in hybrid with up to 29 miles of electric-only operation. With the gas tank included, you get roughly 600 miles of combined driving range. (That's DC to Atlanta, had Jefferson wanted to visit Atlanta.) Visually, there's little to distinguish this PHEV from a conventional Optima. Its alloy wheels are aerodynamically cleaner and front fascia less disruptive - and includes an active air flap, no less. The exterior design, though dated, still impresses. A spacious interior is what you'd expect from Kia. And so, regrettably, are some hard plastic surfaces. That plastic is appropriate in a $20,000 Soul, less so in a $40,000 Optima Plug-In. Nothing here is completely off-putting, and we've always liked Kia's integration of audio and A/C controls. But so much is good about the Optima that you expect something nicer as you slide behind the wheel. The front seats are both supportive and accessible. Our test vehicle, equipped with $5,250 of EX Technology, offered a panoramic sunroof, heated and ventilated front seats, a power front passenger seat with adjustable lumbar, and heated outboard rear seats. That same package also includes a bundle of safety technology, including a forward collision warning system, advanced smart cruise control, blind spot detection, lane departure warning, and rear cross traffic alert. A modern hybrid generates a lot of info, and learning to access it all will require more than the few hours we had in the car. Your economy – the Optima's innate efficiency and your driving style – is available at the push (or two) of a button. And you can choose from all-electric EV or hybrid mode by using Kia's Mode Select control.

2017 Kia Cadenza is a redesigned head scratcher

The second-generation Kia Cadenza has unexpectedly bowed at the 2016 New York Auto Show, and we're left wondering how this thing even survived to get a second generation. The Cadenza has been on sale since 2013 and it's never sold over 10,000 units in one year. Even if you combine US and Canadian sales, Kia's best year for the Cadenza was 2014, where it sold just 9,427 cars. So, what's Kia done to the second-gen car to improve on that disappointing stat? Perhaps the biggest change is the platform the Cadenza rides on. It's lighter and stiffer, which means it's probably going to be a far better dancer than the boat-like first-gen model. Cutting the weight also allowed Kia's engineers to fit more sound deadening, which alongside a sound-absorbing laminated windshield and front windows will likely lead to a quieter ride. Better handling and a quieter ride? Okay Kia, we're paying attention. The Cadenza's 3.3-liter V6 still sits under hood, but it's paired to an eight-speed automatic for the first time. That, alongside a new tune for the engine, should improve on the current Cadenza's 19-mile-per-gallon city and 28-mpg highway stats. Kia hasn't released an estimate of how much of an improvement it will be, but we suspect it'll be modest. Frankly, we're still a bit confused about why Kia is carrying on with the Cadenza. Its rivals sell in far higher volumes – in 2015, the Nissan Maxima sold over 40,000 units, the Buick LaCrosse did 42,000, and the Toyota Avalon did 60,000 – and two of those cars, the Maxima and LaCrosse, have just been fully and completely reworked. Then take into account America's increasing disdain for sedans/infatuation with crossovers, and Kia pushing through the second-gen Cadenza is just a puzzling move. Still, the visual updates, platform improvements, and powertrain changes are positive – will that be enough to turn around the Cadenza's struggling sales? We have no idea, but things can't get much worse.
