The 2017 Cadillac XT5 debuts a completely new structure and chassis that enable the crossover to be space efficient, lightweight, and deliver agile driving dynamics.
Though unconfirmed by GM/Cadillac personnel, the architecture is known internally as the C1XX platform. The architecture features a transverse engine orientation sending power to the front wheels as standard, while an all-wheel drive system is optional.
The XT5 benefits from GM-Cadillac’s latest prowess in vehicle lightweighting. It is 278 pounds (126 kg) lighter than the second-generation SRX it replaces, while also weighing less than competitors. For instance, the XT5 is:
- 100 pounds (45 kg) lighter than the Audi Q5, despite the Cadillac being seven inches longer
- Over than 650 pounds (295 kg) lighter than the Mercedes-Benz GLE-Class
But lighter weight doesn’t mean that the Cadillac XT5 makes compromises in other areas such as rigidity, space, or crash performance. Cadillac says that the crossover achieves the weight savings with “no compromise to body rigidity and crash performance.”
The XT5’s wheelbase measures in at 112.5 inches (2857 mm), an increase of two inches (50 mm) compared to the 110.5 inch (2807 mm) wheelbase of the 2016 SRX it replaces, enabling the XT5 to have 3.2 inches (8.1 cm) more rear-seat legroom than the SRX. What’s more, the XT5’s rear seat reclines and slides fore and aft. By comparison, the rear seats of the SRX were only capable of reclining, and not capable of sliding back and forth.
To achieve this, engineers applied many of the same techniques used on the Cadillac CTS and ATS sport-luxury sedans – the lightest cars in their respective segments. These include the use of laser welding, ultra high-strength steel and advanced analytics that ensure a stronger structure, and excellent crash performance with less overall bulk.
“The new XT5 takes the lessons learned from Cadillac’s highly acclaimed lightweight and agile luxury cars and adjusts the formula for the unique desires of the crossover vehicle customer,” says David Leone, Cadillac executive chief engineer. “Reducing mass and bulk not only improves driving dynamics, it enables us to improve interior space and fuel efficiency.”
Other C1XX Uses
We believe that a longer variant of the XT5’s C1XX platform will be used to underpin other future GM vehicles, including the next-gen Chevrolet Traverse, GMC Acadia, Buick Encalve, and Buick Enspire (along with its rumored Opel-Vauxhall variant).
