The new Cadillac XT4’s confident, athletic appearance is complemented by great agility. It is characteristically Cadillac in refinement and responsiveness, but with a youthful edginess derived from the brand’s critically acclaimed sports sedans.
It starts with an all-new Cadillac 2.0L Turbo engine. This advanced, power-dense inline-four-cylinder — 118.5 hp per liter — features an industry-first tripower system. The system is designed to optimize performance and efficiency by having three distinct operating modes, including high and low valve lift and Active Fuel Management (cylinder deactivation).
The engine also features a twin-scroll turbocharger to enhance torque production at lower speeds, as well as direct injection, active thermal management and stop/start technologies. Output is SAE-certified at 237 hp (177 kW) and 258 lb-ft of torque (350 Nm). A nearly flat torque curve gives the XT4 surprising responsiveness throughout the engine’s RPM range.
A nine-speed automatic transmission is paired with the new engine, helping the XT4 achieve a Cadillac-estimated 30 mpg in highway drivingiv. The vehicle also features the next generation of electronic precision shift, which features an intuitive shifting sequence.
When it comes to channeling the XT4’s power to the pavement, a strut-type front suspension and five-link independent rear suspension are tuned to balance refinement with responsiveness. The standard Driver Select Mode allows that tuning to be adjusted on demand for different driving styles and road conditions.
A twin-clutch all-wheel-drive system is available and offers the convenience of decoupling entirely from the rear wheels when the driver chooses, eliminating drivetrain friction.
XT4 Sport’s available Active Sport Suspension features Continuous Damping Control and takes driving dynamics and control to a higher threshold, using electronic sensors to monitor the road in real time and making damping adjustments every 2 milliseconds.
The XT4 is also the first Cadillac to introduce electro-hydraulic braking assist, which supplants the traditional vacuum-assisted power braking system with an electro-hydraulic system that enhances fuel economy and takes up less space under the hood.
