2027 Cadillac STS Redesign, Specs, Features – The 2027 Cadillac STS is a striking resurrection of one of Cadillac’s most revered nameplates, reborn with a modern mission: to deliver executive-level sophistication in a sleek, tech-savvy package. Gone are the traditional proportions and understated visuals of past STS models. The new version rides on GM’s flexible BEV3 electric platform, hinting at a near-silent, ultra-smooth ride. This structural shift allows for longer wheelbase proportions, enhanced interior space, and dramatically refined handling dynamics. 2027 Cadillac STS Redesign

Exterior & Interior
Slide into the 2027 Cadillac STS, and you’re greeted with a cocoon of premium materials, curated technology, and quiet craftsmanship. Cadillac’s obsession with interior quality is apparent immediately, with Nappa leather, open-pore wood, aluminum, and ambient LED lighting wrapped seamlessly into a flowing dashboard. The crown jewel is the 38-inch curved OLED display, split between an instrument cluster and infotainment system, boasting sharp resolution and intuitive layout.
Seating is both stylish and functional, offering heated, ventilated, and massaging capabilities for front passengers. Rear passengers aren’t left behind—plush seats, independent climate control, and twin infotainment screens mounted behind the front seats create an environment tailored to executives and family buyers alike. Sound insulation is top-tier, aided by acoustic glass and active noise cancellation that eliminates road buzz. There’s also a panoramic glass roof with electrochromic dimming, expanding the cabin visually while controlling sunlight with a touch.
Tech is smartly integrated: wireless Apple CarPlay and Android Auto are standard, as is a native Google interface for maps, assistant, and Play Store access. A 36-speaker AKG Studio Reference sound system transforms the STS into a rolling concert hall. Digital keys via smartphone, facial recognition unlock, and biometric seat memory settings complete the futuristic feel. The STS interior isn’t just about showing off—it’s about delivering function and flair with confidence.
Designers approached the STS with a no-compromise attitude, giving the sedan a completely fresh aesthetic that mixes elegance with contemporary edge. The front fascia is unmistakably Cadillac, dominated by the brand’s vertically stacked LED lighting signature and a wide, shield-style grille finished in dark chrome. Sharp body lines, subtle sculpting across the fenders, and a sloping fastback-inspired roofline lend the 2027 STS a presence that’s sleek but never anonymous. This is a car designed to turn heads in corporate parking lots and valet circles alike.
The STS doesn’t just echo luxury—it defines it with details like flush-mounted door handles, active aero shutters, and dynamic lighting sequences that welcome the driver on approach. The long hood and low beltline signal performance beneath the refinement, and its profile has hints of European grand tourers. Cadillac is taking clear aim at the Mercedes E-Class and BMW 5 Series, but with an unmistakable American flavor. 2027 Cadillac STS Redesign
2027 Cadillac STS Specs
Engine & Performance
Cadillac offers the 2027 STS with two distinct drivetrains: a fully electric model and a range-extended plug-in hybrid version aimed at transitional markets. The electric version is powered by GM’s Ultium dual-motor setup, delivering 490 horsepower and 510 lb-ft of torque to all four wheels. This translates to a 0–60 time of 4.5 seconds—quick for a luxury sedan, yet effortlessly smooth thanks to linear power delivery. Instant torque and near-perfect weight distribution make the STS as competent on a winding road as it is on the freeway.
For those preferring flexibility, the STS PHEV uses a turbocharged 2.0L engine paired with two electric motors and a 24 kWh battery, producing a combined 385 hp and offering around 60 miles of electric-only range. This model targets buyers in regions where charging infrastructure is limited but who still want a taste of EV living. Both variants come with adjustable air suspension, Magnetic Ride Control 5.0, and an electronic limited-slip rear differential for crisp cornering behavior.
Drive modes adjust throttle response, steering weight, suspension firmness, and torque distribution. Touring mode prioritizes comfort and efficiency, while Sport and Custom modes unlock more aggressive characteristics. Regenerative braking is adjustable, and one-pedal driving can be enabled in both electric and hybrid models. The 2027 STS isn’t just a sedan—it’s a precision-built, performance-capable cruiser for the modern luxury driver.
2027 Cadillac STS Fuel Economy
Efficiency is another strong suit of the 2027 Cadillac STS. The electric variant boasts an EPA-estimated 350 miles of range, supported by a 111 kWh Ultium battery pack. Thanks to its 800-volt architecture, the STS can charge from 10% to 80% in just 18 minutes using a 350 kW DC fast charger. At-home Level 2 charging replenishes about 35 miles of range per hour. For urban dwellers, Cadillac’s PlugShare app integration helps locate compatible charging stations and offers route planning with charging stops.
The plug-in hybrid STS offers impressive versatility, delivering up to 60 miles of all-electric driving before the gas engine kicks in. When used primarily for commuting, drivers could go weeks without visiting a gas station. Once the gas engine engages, the combined range extends to nearly 580 miles. Cadillac estimates fuel economy at 85 MPGe combined for the PHEV and equivalent of 100 MPGe for the all-electric variant. 2027 Cadillac STS Redesign
2027 Cadillac STS Safety Features
Safety in the 2027 Cadillac STS goes far beyond airbags and sensors—it’s baked into every layer of the car’s technology. Super Cruise 2.0 headlines the suite, offering hands-free driving on compatible highways with automatic lane changes, adaptive cruise, and real-time updates through HD GPS and LiDAR mapping. The system now works in traffic jams and urban environments, and uses an infrared camera to monitor driver attention.
Cadillac SmartShield includes forward collision warning with pedestrian and cyclist detection, automatic emergency braking, rear cross-traffic alert with braking, and active blind zone steering assist. A 360-degree camera with 3D visualization overlays ensures full visibility during low-speed maneuvers. Parking assist with automatic parallel and perpendicular parking is standard, while an available self-parking system allows remote summon via smartphone.
Structural safety is just as impressive. The STS uses a mix of ultra-high-strength steel and aluminum to protect the passenger cell in side and frontal impacts. Ten airbags, including a front center airbag and rear occupant side bags, come standard. Cadillac has also included post-collision autonomous braking, emergency EV system isolation, and smart occupant detection to prevent children or pets from being left behind accidentally.
