All of General Motors’ 2015 model-year full-size SUVs are set to receive interim model year updates. We’ve already given you the rundown on the updated 2015i Chevrolet Suburban and Tahoe, and now The General has applied its enhancements to the 2015 GMC Yukon Denali and Denali XL.
If you’ve been wanting to buy a 2015 Yukon Denali or Denali XL but held out, than congratulations, you’re either well-informed or very lucky. That’s because all GM vehicles with the 6.2-liter EcoTec3 V8 engine are being updated with the automaker’s new 8L90E eight-speed automatic transmission for the interim model year.
The 8L90E uses smaller steps between each gears, allowing the vehicle to stay out of the higher RPM ranges, resulting in better fuel economy. Yukon Denalis equipped with the eight-speed trans will return 22 MPG highway and 16 city, compared to the 21 highway/15 city ratings with outgoing 6L90E six-speed. The 8L90E can also handle more torque, shifts faster and operates more smoothly.
In addition to these enhancements, all Yukon and Yukon XL models will receive a range of new technologies. Just like the Tahoe and Suburban, a new hands-free power liftgate has been added with the interim updates, along with a wireless charging mat integrated into the center console lid. OnStar’s 4G LTE Wi Fi hotspot with a 3GB/3-month trial is also standard.
Rounding out the updates is GMC’s IntelliLink infotainment system, which has been updated to provide incoming text message alerts. Owners of 2015 Yukon and Yukon XLs can also now receive tutorials on these new features via the Yukon app for tablets, smartphones and other devices. The Yukon app will be available for both Apple iOs and Android devices, GMC says.
