Motor Trend is reporting that Hyundai and Kia are working on creating a new 10-speed automatic transmission. The dual-headed Korean automaker unveiled a new eight-speed automatic gearbox in the 2012 Hyundai Genesis Sedan. Along with revisions to the 3.8-liter V6 engine, the transmission helped the model generate up to two miles per gallon better on the highway than its predecessor.
According to Motor Trend, news of the 10-speed transmission comes courtesy of unnamed sources inside Bloomberg, and the technology could show up in a production model as soon as 2014. Beyond that, details are notably scarce. Two extra cogs would likely help improve fuel economy at a moderate cost to the company and consumer, especially if engineers were able to translate much of the design of the eight-speed into the new gearbox. Stay tuned.
