    Paris Motor Show: Kia Optima T-Hybrid


    • Kia Shows Off A Diesel Mild-Hybrid


    One of Kia showings at this year's Paris Motor Show is a intriguing hybrid concept housed in the current Optima. The Optima T-Hybrid Concept pairs a 1.7L diesel four-cylinder featuring a turbocharger and electric supercharger, and a a small electric motor with a 48-volt lead-carbon battery. The mild-hybrid setup allows the vehicle to travel on all-electric at low speeds and when cruising. When slowing down, the setup helps recharge the battery pack. Kia isn't talking about fuel economy or emissions as the company is still developing the powertrain.

    “In future, our mild hybrid powertrain could offer Kia customers greater performance and lower running costs, without sacrificing the qualities they expect of a Kia car – enjoyable handling, a comfortable ride and high quality. Demonstrated for the first time in the Optima T-Hybrid, the technology will lower the total cost of ownership of our cars, yet still keep them affordable as an outright purchase for customers,” said Michael Cole, Chief Operating Officer for Kia Motors Europe.

    Kia to showcase diesel-electric Kia Optima T-Hybrid at Paris

    - More power and lower emissions for Kia Optima mild hybrid show car

    - Innovative new powertrain pairs 1.7-litre CRDi turbo-diesel engine with 48V lead-carbon battery, small electric motor and an electric supercharger- Kia Optima T-Hybrid concept previews new powertrain technology ahead of future mass production

    Frankfurt, 29 September 2014 – Kia will reveal the new Kia Optima mild hybrid show car at the 2014 Paris Motor Show on 2 October, the first application and demonstration of the brand's innovative new mild hybrid powertrain.

    The Kia Optima T-Hybrid (turbo hybrid) concept is powered by the model's existing 1.7-litre CRDi turbo-diesel engine, paired with a small electric motor, powered by a 48V lead-carbon battery. The diesel-electric powertrain concept, which was previewed at the 2014 Geneva Motor Show, enables the Optima T-Hybrid show car to be driven in electric-only mode at low speeds and when cruising, with deceleration serving to recharge the battery pack.

    Lead-carbon batteries were chosen for the mild hybrid powertrain as, unlike lithium-ion batteries, they require no active cooling and are easier to recycle at the end of the unit's lifecycle.

    The vehicle features a zero-emissions stop-start system, and a new belt-driven starter generator replaces the conventional alternator, meaning the engine can restart with almost no noise or vibration. Installing the powertrain in the Optima sedan has enabled engineers to fit a smaller vehicle battery and starter motor, enhancing weight distribution and handling.

    The system also allows the installation of an innovative electric supercharger for the CRDi engine, in addition to the conventional turbocharger, providing improved power and torque at all engine speeds. The electric supercharger in particular helps to boost torque and engine response at low engine speeds.

    Still under development, no specific performance or fuel economy figures are confirmed for the powertrain or its application in the Optima T-Hybrid show car. However, Kia's engineers are targeting a significant reduction in CO2 tailpipe emissions and fuel consumption and a power increase of between 15 to 20 percent for any model which could be equipped with the new powertrain. Currently, the Optima's 136ps 1.7-litre engine produces CO2 emissions of 128 g/km (when fitted with ISG stop-start).

    "In future, our mild hybrid powertrain could offer Kia customers greater performance and lower running costs, without sacrificing the qualities they expect of a Kia car – enjoyable handling, a comfortable ride and high quality. Demonstrated for the first time in the Optima T-Hybrid, the technology will lower the total cost of ownership of our cars, yet still keep them affordable as an outright purchase for customers," commented Michael Cole, Chief Operating Officer, Kia Motors Europe.

    "The new mild hybrid system is our flagship technology for improving the efficiency of our internal combustion-powered models. In future, technology such as this will help Kia further reduce fleet emissions in Europe," added Cole.

    While under development, no plans have been confirmed yet for mass production of the Kia Optima T-Hybrid show car. The T-Hybrid powertrain remains under consideration for new Kia models in the future.

    While it sounds cool and I have posted in other threads that the Volt needs to have a diesel and CNG option for the generator, I do find the pictures and info a bit lean. Excited still for them to do this.

      Stumbled across this story on the BBC that shows that 4 major cities will have a ban on all diesel auto's and Trucks by 2025.
      http://www.bbc.com/news/science-environment-38170794
      Paris
      Mexico City
      Madrid
      Athens
      These four cities are implementing complete bans on Diesel to improve air quality. Campaigners are pushing to have London Diesel free also by 2025. Very interesting read, plus I see they are converting more roads into bicycle lanes only. Bummer but the future is an ICE free future for many cities

      When I go back and look at the various Kia Optimas I have driven for Cheers & Gears, there has been one variant that I haven’t driven, the 2.0L turbo-four. But this changed back over the summer when a 2016 Kia Optima SXL came into the Cheers & Gears’ Detroit bureau for a week-long evaluation. The SXL serves as the Optima’s flagship trim with more premium materials and the turbo-four.
      As I mentioned in my Optima EX review from earlier this year, the redesigned Optima looks familiar to the previous model. But that isn’t a bad thing per say. It is still as sharp looking as the previous model and the changes done such as a new trunk lid, LED taillights, a smaller grille, and reshaped headlights. The SXL takes it a step further with a set of 18-inch alloy wheels, Turbo badging on the fender vents, and a little bit more chrome. Finished in a dark blue, the Optima SXL is damn good looking midsize sedan. You won’t find many differences in the SXL’s interior compared to other Optima’s. The key one is the seats being wrapped Nappa leather with a quilted pattern. If I am being honest, I can’t really tell difference between the Nappa leather and the standard leather used on other Kia models.  But what I can tell the difference with is the materials used in the SXL’s interior. Kia swaps the soft-touch plastic used on the dash and door panels for stitched leatherette. This is to give the impression that you’re in something more expensive and it works very well. The Optima SXL’s backseat is slightly tighter than the one found in the Optima EX. Why? The SXL comes with a panoramic sunroof as standard, which eats into headroom. Let’s talk about the engine. The SXL features a 2.0L turbocharged four-cylinder with 245 horsepower and 260 pound-feet of torque. This is paired with a six-speed automatic. Leaving a stop, it takes a moment for the engine to fully wake up and you can’t help but wonder where is the power. At first, I thought this new 2.0L developed a bad case of turbo-lag. But I soon realized that it was a lazy throttle that was causing this issue. This is something we have been noticing in recent Hyundai and Kia models equipped with the turbo engine. Once you get over the lazy throttle, the engine moves the Optima with some authority. Merging onto a freeway or making a pass is no problem as the turbo quickly spools up and gives the necessary thrust. It doesn’t hurt the engine is very refined. EPA fuel economy figures stand at 22 City/32 Highway/25 Combined. I achieved a not too shabby 26.1 mpg average for the week. One of my biggest complaints about the last Optima I drove was the uncomfortable ride. The tuning on the EX model let in more bumps and road imperfections inside than what I was expecting. To my surprise, the SXL featured a more comfortable ride. Despite featuring larger wheels, the SXL was able to iron out most bumps and imperfections. I can’t explain why there is a vast difference in terms of ride quality between the two trims at this time. The SXL does retain the sharp handling that we liked in the Optima EX. Body motions are kept in check and the steering provides a nice heft when turning. Some will lament that the steering doesn’t have the same feel as something like the Mazda6, but this has to be Kia’s best effort yet.  The Optima SXL begins at $35,790 and that includes every option available on the Optima as standard equipment - 18-inch alloy wheels, dual-zone climate control, heated and ventilated front seats, a Harman/Kardon audio system, navigation, blind-spot monitoring, adaptive cruise control, surround view camera system, and much more. Some might balk at the price. But considering what the SXL brings to the table, along with its improved ride quality, it is very much worth the price. Plus, you might be able to work out a deal to where you’ll be able to cut the price. We’ve seen dealers cutting about $2,000 to $4,000 off Optima SXLs in an effort improve sales of the midsize sedan. Who knows, you might be able to get one of best equipped and decent driving midsize sedans at a surprising price. Disclaimer: Kia Provided the Optima SXL, Insurance, and One Tank of Gas
