2008 Cadillac STS Review

An all-new look for 2008, an array of high-tech options, and a more-powerful V-6 engine all at a reasonable price.

Reviewed by Automotive on


The 2008 Cadillac STS classifies as a large luxury sport sedan available in two primary models, named for their engine types. The STS V-6 contains an all-new V-6 engine with direct fuel injection. This new engine proves more powerful than the one it replaces, but also adds fuel efficiency and runs more cleanly than previous models. The STS V-8 draws power from a 4.6-liter, V-8 engine with sophisticated computer management. The 2008 Cadillac STS provides a middle option between Cadillac’s large DTS sedan and the midsize CTS sport sedan. The STS’ ride and handling impress consumers, especially considering its large size. At a price that undercuts many competitors, it makes a good choice for drivers looking for value in a luxury vehicle.

What's New

The 2008 Cadillac STS is completely revamped, with new exterior and interior styling, a host of tech-savvy options, more horsepower, and additional safety features.

A Platinum Edition debuts for 2008, with special exterior and interior trim and larger wheels.


The 2008 Cadillac STS features crisp lines and an angular silhouette. A bold, egg-crate grille looks especially distinctive. Chrome air extractor vents add detail to the flanks, and more subtle chrome accents can be found on the door handles and rocker flares. The rear features vertical taillights bracketing a tall and squared-off trunk, a trapezoidal license plate inset, and three-inch polished aluminum exhaust tips exiting below each end of the rear bumper. The Platinum Edition features 18-inch chrome-finished wheels, an even brighter chrome-finished grille, bright chrome inserts on the exterior door handles, and special Glacier Gold paint.


The 2008 STS’ interior feels luxurious, with comfortable but supportive seats that adjust in many ways. It also provides ample storage space and superior sound systems. Standard features include leather upholstery, aluminum interior trim, dual-zone automatic climate control, a Bose AM/FM/CD stereo, an auto-dimming rear-view mirror, and full power accessories.

The popular V-6 Luxury Package adds two-driver memory for seats, mirrors, climate, and radio controls; a six-disc in-dash CD-changer; Eucalyptus wood trim on the instrument panel, steering wheel, console, and center stack; heated and ventilated front seats with four-way power lumbar support; heated rear seats and steering wheel; a tire pressure monitor; and a universal home remote. Much of the content of the V-6 Luxury Package comes standard on the V-8 model. The V-8 Luxury Package adds Bose 5.1 surround sound and heated and ventilated front seats.

The STS Platinum model, new for 2008, has a very distinctive look and feel, with a hand-cut, sewn, and wrapped instrument panel and door trim, Tuscany leather seats, olive ash burl wood and chrome accents, plus a heated leather-wrapped steering wheel.

Performance & Handling

An all-new, direct-injected, 3.6-liter V-6 powers the 2008 STS V-6. At 302 horsepower and 272 lb-ft of torque, it not only produces more power, but also proves more fuel-efficient and runs cleaner than previous engines. The V-8 model gets powered by a 4.6-liter V-8, making 320 hp and 315 lb-ft of torque. Both engines come only with a six-speed automatic transmission, and both can be ordered with rear or all-wheel drive.

A new Performance Handling Package provides an option for the rear-drive V-6 and both rear- and all-wheel-drive V-8 models. It includes StabiliTrak (with active steering on all-wheel drive V-8 models), high-performance Brembo brakes, and chrome-plated wheels fitted with performance summer tires.


Anti-lock disc brakes, stability control, and a full complement of airbags come standard on every Cadillac STS. New safety technologies for 2008 include Cadillac's latest Lane Departure Warning and Blind Zone Alert systems, plus a StabiliTrak electronic stability control system. In V-8, all-wheel-drive (AWD) models, this system has a special front-wheel steer feature that automatically turns the front wheels into a skid when the rear wheels lose traction to quickly restore control. Another new feature, the Intellibeam automatic high-beam system available on the V-8, automatically switches between high and low beams based on the distance of oncoming traffic.

EPA Fuel Economy
