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 beefs up HB20 R-Spec in Brazil

If you've been following the news from the Sao Paulo Motor Show, you'll likely have seen not only a series of new concept cars, but also a whole mess of production vehicles you never knew existed because they were developed specifically for the Latin American market. One of them is the Hyundai HB20.
Hyundai Brasil makes the HB20 in Sao Paulo for local consumption in three forms: there's the HB20 hatchback, HB20S sedan and HB20X crossover. It's the former which it has transformed into the R-Spec concept you see here.
Decked out in matte blue, the HB20 R-Spec concept packs an aggressively upgraded aero kit, extra cooling ducts, 17-inch alloys, LED headlights and an interior with leather trim and striped seats. Even if we don't know what's under the hood, it all looks pretty convincing, and makes us wish Hyundai would offer it Stateside as part of the Accent family with which it shares its underpinnings.

Hyundai, ARK Performance combine for SEMA-bound Legato Genesis Coupe

The latest body-kitted Hyundai Genesis Coupe scheduled to appear at the Specialty Equipment Market Association (SEMA) show in Las Vegas is the ARK Performance Legato Concept. In a nod to performance fiends, Hyundai built a stroker V6 good for 400 horsepower and 425 pound-feet of torque to really set the coupe off.
The extra power is a very good thing when one considers how fast the Legato Coupe looks. Speaking of the Italian musical term "legato," it translates to "tied together," and it was the theme ARK adhered to when it designed the car. In ARK's words, the the Legato conveys "the seamless integration of exotic design, tuned performance and luxury coupe interior ambience."
ARK's body kit includes front and rear bumpers, side skirts, deck lid and "wide-body cues." The 3.8-liter V6 was stroked to 4.0 liters courtesy of JE pistons, connecting rods and a billet steel crankshaft. ARK supplied an intake system and headers, and bolted on a lightweight pulley kit. An ARK oil cooler keeps the engine running at the right temperature. The tuning company also bolted on one of its dual-mass flywheels and carbon clutch kit to handle the extra power.
