Hyundai twin-charged 1.8L GDCI gas engine expected to be more efficient than 2.0L diesel

Despite the growing trend of automakers offering diesel-powered or electrified powertrains, there's still a whole lot that can be done with the good-old gasoline internal combustion engine. And at Hyundai, that's exactly what's being worked on - new gasoline engine technologies that improve both performance and efficiency. During an event at the automaker's technical center in Superior Township, MI on Friday, Hyundai gave Autoblog a glimpse into the future, offering up preliminary details on its new GDCI (Gasoline Direct-Injection Compression) engine - something that will be heading to production soon.
Hyundai's main goal with this GDCI engine is to "achieve diesel levels of fuel efficiency with conventional gasoline," according to Nayan Engineer (yes, his last name is Engineer), one of Hyundai's powertrain gurus. What's more, Engineer says the GDCI engine will offer "equal to better performance than conventional gasoline engines" and will have a "lower system cost [than] diesel engines."
Hyundai expects a 1.8-liter GDCI engine to be more efficient than a comparable 2.0-liter diesel engine with similar performance.

Hyundai Genesis Coupe joins the SEMA fray

With several tuned rides already headed to the show, Hyundai finishes off this year's slate with a mean-looking Genesis Coupe from Tjin Edition painted in a searing shade of green. The coupe's 3.8-liter V6 gets a Vortech supercharger and front-mounted intercooler to help push the claimed output to over 500 horsepower. A set of KW coilovers and Baer brakes also make sure the coupe handles and stops just as well as it accelerates. Tjin's custom shade of lime green paint will draw attention to this Genesis Coupe at Hyundai's booth. Once attendees get closer, they can check out the car's tweaked front lip, trunk lid, and rear spoiler from Unique Fabrication. Meanwhile, the interior mixes performance and comfort by combining a roll cage and Alea leather upholstery. The Tijn Edition Genesis Coupe will join Hyundai's other offerings at this year's SEMA Show in Las Vegas on November 3. TJIN EDITION ROUNDS OUT HYUNDAI'S SEMA LINEUP WITH EXTREME GENESIS COUPE FOUNTAIN VALLEY, Calif., Oct. 26, 2015 – Rounding out Hyundai's 2015 SEMA lineup, TJIN Edition RoadShow has revealed details on its convention-defying Genesis Coupe. For Neil Tjin's first official Hyundai vehicle built for SEMA, the builder turned to underground racing for inspiration to create this mad, 500 horsepower racer. The vehicle will be revealed at Hyundai's SEMA press conference on November 3 at 11:30 a.m. PT. At the heart of TJIN's Genesis Coupe is Hyundai's 3.8-liter "Lambda" V6 engine, which has been boosted via a Vortech supercharger kit built by the power gurus from Bisimoto Engineering. With the addition of a free-flowing exhaust system, Vortech front mount intercooler and blow-off valve, the vehicle now produces more than 500 horsepower. With the addition of Rotiform 19-in. 3-piece HUR wheels, custom Baer x CBA Extreme Plus brake calipers and Falklen FK345 tires, the vehicle's stopping power is now on par with its go-fast performance. The vehicle now sits lower on KW coilovers to give a more aggressive stance. Unique Fabrication supplied a custom front lip, rear spoiler and custom trunk lid, and the exterior was finished in a custom Kylie Tjin Axalta green paint job. "The Tjin Edition Hyundai Genesis is the perfect mix of speed and style," said Neil Tjin, president, TJIN Edition RoadShow.

Next Hyundai Genesis to get HTRAC all-wheel drive

Hyundai's Genesis sedan has been quite the sales success since it first launched in 2008 as a 2009 model, but its rear-wheel drive nature has limited its sales appeal in cold-weather states versus competitors like Audi, BMW, Cadillac and Mercedes-Benz, all of whom have offered all-wheel drive in their lineups for years now. We've been hearing that Hyundai has had plans to remedy this shortfall for some years now, and we finally have official confirmation that four-corners-driven traction is coming for the second-generation Genesis.
Dubbed "HTRAC," Hyundai isn't saying much about the new system, other than noting it will offer "select driving modes for a sophisticated and tailored driving experience" and that it will also electronically control the torque split between the car's front and rear axles. HTRAC was developed all over the world, including on the Nürburgring and on Korea's Yeongam Formula One circuit, as well as winter testing in Europe. Oh, and in case you didn't already figure it out for yourself, the "H" in the name stands for "Hyundai" and "TRAC" is short for "Traction."
No word yet on when the system will become available, but Hyundai promises that the second-generation Genesis will make its world debut in its home market later this year. Although no official images or further details have been revealed yet, an undisguised look at the 2015 sedan came to light yesterday, suggesting a reveal is imminent.
