2008 Lexus SC 430 Specs | Engine, MPG & Value

The 2008 Lexus SC 430 packs a 4.3L V8 with 288 hp, hits 60 mph in 5.8 seconds, and gets 19 MPG combined in a retractable-hardtop convertible.

The 2008 Lexus SC 430 specs read like a luxury grand tourer’s recipe: a 4.3-liter V8, a power-retractable hardtop, and a cabin trimmed in leather and real wood. This two-door convertible was a single-trim model — one engine, one transmission, no packages or option tiers. Here is a complete look at the final year of the SC 430.

Engine and Performance

The 2008 SC 430 is powered by a 4.3L DOHC 32-valve V8 with Continuously Variable Valve Timing (VVT-i). It produces 288 horsepower at 5,600 rpm and 317 lb-ft of torque at 3,400 rpm, with a 10.50:1 compression ratio. Premium gasoline is required for full power — regular fuel may reduce output. The engine pairs with a 6-speed Sequential Shift automatic transmission driving the rear wheels through a 3.77 final drive ratio.

The car reaches 60 mph in 5.8 seconds and tops out at 149 mph. Gear ratios are 3.30 (first), 1.96 (second), 1.35 (third), 1.00 (fourth), 0.73 (fifth), and 0.58 (sixth), with a 2.95 reverse. The sequential shift feature allows manual control via the gear selector or steering wheel paddles. The 3UZ-FE V8 is known for smooth power delivery and long-term reliability — the same basic engine architecture served Lexus for years.

Fuel Economy, Dimensions, and Weight

The EPA rates the SC 430 at 16 MPG city and 23 MPG highway, for a combined 19 MPG. With a 19.8-gallon tank, estimated range comes to about 317 miles in city driving and 455 miles on the highway. Real-world owners typically report 15–18 MPG in mixed driving. Premium fuel is needed to hit the rated figures.

The car weighs 3,840 pounds and measures 178.5 inches long, 72.0 inches wide, and 53.1 inches tall on a 103.1-inch wheelbase. Ground clearance is 5.6 inches. Cargo volume is 8.80 cubic feet with the top up, and passenger volume is 75.0 cubic feet. The aluminum retractable hardtop stows cleanly beneath the rear deck lid in about 25 seconds, preserving a coupe silhouette when lowered.

Pricing, Features, and What to Know

Standard equipment was generous: a Mark Levinson 9-speaker, 240-watt sound system with a 6-disc CD changer, DVD navigation with Bluetooth hands-free calling, leather seats with power adjustment and heating, a power tilt-and-telescoping steering wheel wrapped in wood and leather, adaptive headlights, keyless entry, cruise control, and an integrated garage door opener. The original warranty covered 48 months or 50,000 miles (basic) and 72 months with unlimited miles (powertrain).

Safety equipment includes driver and front-passenger knee airbags, an occupant-detection system, four-wheel disc ABS with Electronic Brake Force Distribution and Brake Assist, traction control, Vehicle Stability Control, and a tire-pressure monitoring system. Child seat anchors and child door locks are also standard.

A few caveats: the engine requires premium fuel for full power; the standard 18-inch wheels deliver a firmer ride than expected from a luxury convertible; and the rounded “bathtub” styling draws mixed reviews. The DVD-based navigation system feels dated by modern standards — maps lack traffic data and points of interest are years old. Check that the retractable top mechanism operates smoothly, as repairs can be expensive. The SC 430 is a US-market vehicle; European and Japanese versions may differ.
