Borgwarner just announced that its variable turbine geometry (VTG) turbochargers will be used in the new 4 cylinder diesel engines on the new Hyundai ix35s and Kia Sportages.
BorgWarner’s new turbochargers provide a variety of enhancements that help these vehicles operate more efficiently, using less fuel and producing fewer emissions.
In a press release, Roger Wood, President and General Manager, BorgWarner Turbo Systems, commented on the news:
“BorgWarner’s latest advancements in turbocharging technology for modern diesel engines achieve optimum power output with the greatest fuel economy. We are pleased to provide localized production and engineering in Korea to support our successful, long-standing partnership with Hyundai Motor Corporation.”
This is good news indeed, I’ve always wondered where could Hyundai and Kia be getting the technology for their VGT’s. Actually I’m a bit keen on the new Sorento’s 2.2L diesel engine capable of 190 ps. This is really amazing considering that Nissan’s 2.5L Navarra can only muster 174 and Ford’s 3.0 L Ranger VGT at 156. The torque values follows suit too.
I guess only Ford and Hyundai/Kia have VGT on their diesel engines. I work for an Oil firm and I really dig for tech updates, so could you please enlighten me on HOW this technology increases power delivery whilst minimizing fuel consumption.
Lastly, what are there are down sides to this ?
Thanks,
