AutomotiveNews reports that General Motors could be on the road to reconsidering their powertrain options for the 2015 line of full-size SUVs, which include the Chevrolet Tahoe and Suburban, the GMC Yukon and Yukon XL, and the Cadillac Escalade. At some point, this could also include the Chevrolet Silverado and the GMC Sierra as well since they share a lot of mechanical similarities.
According to the report, new diesel mills, hybrid powertrains, and high-geared transmissions could be phased in, retiring the older technology currently being used on the trucks.
“We’ve got some interesting powertrain technologies coming on the SUVs over the next few years,” Jeff Luke told AN, GM chief engineer for the truck division.
Luke cited tough competition and changing mindsets, particularly with the US market’s growing reception of diesel engines. Additionally, GM has a new eight-speed automatic, which could find its way into the new trucks as well with the possibility of a 10-speed unit in the mix as well.
