The GMC Yukon Denali is getting a 10-speed Hydra-Matic transmission developed with Ford Motor Co. and a new, multidimensional grille for the 2018 model year.
The new 10-speed will offer smoother shifting and better efficiency from the carryover 6.2-liter V-8 engine than the eight-speed it replaces, GMC said.
Besides creating an updated look, the new grille increases airflow to the radiator, GMC said. Active shutters behind the grille close to reduce drag under certain highway-driving conditions.
The SUV is scheduled to go on sale this fall and will be offered with optional real Mastique Ash wood interior trim.
The Denali trim, available on the regular and extended wheelbase versions, accounts for more than half of all Yukon sales.
GMC did not say whether pricing would change for the 2018 model. The 2017 Yukon Denali starts at $67,260, including shipping.
