5 reasons to buy the 2021 Cadillac CT4

1. Performance meets gas mileage

If you're looking for a powerful yet fuel-sipping sedan, the 2021 Cadillac CT4 fits the bill. Under its hood, the base 2.0L turbocharged four-cylinder engine packs a punch with 237 hp and 258 lb-ft of torque and pairs to an eight-speed automatic transmission. What's impressive is that this powertrain doesn't sacrifice gas mileage for its performance. With an EPA-estimated 27 mpg combined with standard rear-wheel drive or 26 mpg combined with optional all-wheel drive, the 2021 CT4 strikes a respectable balance.

2. Sporty personality

Want to kick things up a few notches? The 2021 Cadillac CT4 delivers an exhilarating driving experience, particularly in the higher-end trims. The Premium Luxury offers an optional 2.7L turbocharged four-cylinder with 310 hp and 350 lb-ft of torque, or there is the top-tier 2021 CT4 V-Series, which uses a more potent 2.7L turbo four-cylinder with 325 hp and 380 lb-ft of torque. This impressive power ensures quick acceleration with a zero to 60 mph time of five seconds (according to the manufacturer), making merging onto highways and navigating winding roads a breeze. The CT4 V-Series also includes standard rear-wheel drive and a 10-speed automatic transmission, further enhancing its performance capabilities.

3. Cockpit comfort

For commuting, running errands, and road trips, the 2021 Cadillac CT4 offers an in-cabin experience with the driver in mind. The front doors provide comfortable ingress and egress from the standard 10-way power adjustable driver and passenger seats, including height adjustments. There is also 38.3 inches of front-row headroom and 42.4 inches of front-row legroom, providing spacious quarters to enjoy your journeys. Finally, the center console, cupholders, and door pockets offer the right amount of storage for your smaller belongings.

4. Modern tech

The 2021 Cadillac CT4 comes very well equipped with cutting-edge technology features, even in its base Luxury trim. All models include an eight-inch touchscreen infotainment system that seamlessly integrates with standard wireless Apple CarPlay® and Android Auto compatibility for quick and easy access to smartphone features. Additionally, the 2021 CT4 includes a standard LED reflective windshield collision alert system, which flashes a red alert across the windshield to draw your attention when a potential collision is detected.

5. Enticing packages

Cadillac offers many optional packages for the 2021 CT4 – and you just might find models with these features to enhance your driving experience. The Technology Package, for instance, adds a digital instrument cluster and a head-up display, while the Bose® Premium Audio package transforms your audio experience with high-quality sound and wireless smartphone charging. Additionally, the Climate Package adds comfort with heated and ventilated seats and a heated steering wheel. For more confidence, the Driver Assist and Driver Awareness Plus packages equip the 2021 CT4 with adaptive cruise control, lane-keeping assist, and blind-spot monitoring.
