Today it was revealed that General Motors next-generation full-size pickup trucks and SUVs are nine months ahead of schedule and will ride on an all-new, lightened chassis being referred to by GM and suppliers as T1XX. In addition to this, the new trucks will have smaller, more efficient engines coupled with fuel saving start-stop technology, according to a Reuters report.
Due to fuel economy standards which go into effect in 2017, both GM and Ford have to find ways to improve the fuel efficiency of their full-size vehicles. As a result, GM will play follow the leader with Ford and offer “a new family of smaller, lighter, more powerful engines similar to Ford’s EcoBoost engines,” Reuters says. These engines will be fuel injected and turbocharged and will feature a stop-start system, like Ford’s 2015 F-150.
Paired with the new engines and lightened chassis will be also be GM and Ford’s co-developed 10-speed automatic transmission for future trucks. The transmission won’t be ready until the new Silverado and Sierra go on sale in the fall of 2018. GM announced earlier this month that an eight-speed transmission will be available on the 2015 Silverado, Sierra and Yukon with the 6.2-liter V8, which is just one of the updates GM has in store for the current K2XX-based trucks.
