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.

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.

Center for Auto Safety wants Hyundai and Kia to recall 2.9M vehicles

DETROIT — A nonprofit auto safety group is demanding that Hyundai and Kia recall 2.9 million cars and SUVs in the U.S. due to consumer complaints that they can catch fire. The Center For Auto Safety said Friday that there have been more than 220 complaints to the U.S. government since 2010 about fires and another 200 complaints about melted wires as well as smoke and burning odors. The complaints involve the 2011 through 2014 Kia Sorento and Optima and the Hyundai Sonata and Santa Fe. Also included is the 2010 through 2015 Kia Soul. The fires are being investigated by the National Highway Traffic Safety Administration as part of a 2017 probe into Hyundai and Kia engine failures. "The volume of fires here make it appear that Hyundai and Kia are content to sit back and allow consumers and insurers to bear the brunt of poorly designed, manufactured and repaired vehicles," Jason Levine, the center's executive director, said. The fire reports have come in from across the country, including a death in Ohio in April 2017, he said. Hyundai says it monitors safety concerns and acts quickly to recall defective vehicles. "We have a robust system in place for monitoring and investigating reported vehicle fires that includes investigation and reporting to NHTSA as required. Vehicle fires can result from a variety of reasons," the company statement said. Kia said it is using company and third-party fire investigators to determine what caused the fires so it can address them. "A vehicle fire may be the result of any number of complex factors, such as a manufacturing issue, inadequate maintenance, the installation of aftermarket parts, an improper repair, arson, or some other non-vehicle source, and must be carefully evaluated by a qualified and trained investigator or technician," the company said in a statement. The Center for Auto Safety filed a petition asking NHTSA to investigate the fires in June. The agency said Friday that it is still evaluating the petition and it has sent information requests to Hyundai, Kia and other automakers about the issue. Levine says the center does not know what's causing the fires. In May 2017 the government began investigating whether the automakers moved quickly enough to recall over 1.6 million vehicles because of engines stalling. NHTSA is looking into three recalls by the related Korean brands, and it's also investigating whether the automakers followed safety reporting requirements.
