Corvette Spec Sheet

"Technology of the Year," 1998 –Automobile Magazine Winner, 1998 "10 Best Engines" award –Ward’s Auto World "Looking back at the Corvette legends of the past, the C5 outruns nearly every of those horsepower heroes, from the ’57 fuelie, to the ’67 427’" –Motor Trend, January 1998

LS1. It’s a code name for a performance masterpiece. And you’ll find it under the hood of every 1999 Corvette.

Specifications include an aluminum block designed for stiffness, strength and low mass, a special camshaft design for excellent breathing and a 10.1:1 compression ratio which helps enhance engine power. Horsepower — 345 at 5600 rpm.

The LS1 may be teamed with either an electronically controlled 4-speed automatic overdrive transmission (standard on coupe and convertible; not available on hardtop) or a 6-speed manual transmission (standard on hardtop; optional on coupe and convertible).

With the LS1 V8, the Corvette driver will enjoy massive low-end torque, combined with the high-revving character that was once strictly the province of small displacement overhead cam engines.

Fuel Efficient
Fuel economy is impressive: an EPA-estimated 18 MPG city/27 highway with optional 6-speed manual transmission (standard on hardtop).

The Numbers Tell the Story
Engine Displacement: 5.7 Liters. Horsepower: 345 at 5600 rpm. Torque: 350 lb.-ft. at 4400 rpm.

Compact, Aluminum Construction
The compact size of the LS1 V8 engine helped Corvette designers achieve a low hoodline for both excellent visibility and a reduced turning circle, while the aluminum construction reduces weight.

Ramming Air and Fuel Together
The LS1’s aluminum cylinder heads and composite intake manifold were designed as a single system to optimize airflow and fuel-flow efficiency.

Smooth Flow of Power
For ultra-smooth performance, all of the LS1’s intake manifold runners are identical in length, resulting in consistent airflow to each cylinder. The fuel injectors have been placed for the most direct fuel spray possible.

Drive-by-Wire Throttle
Electronic Throttle Control is a sophisticated "drive-by-wire" system that provides virtually seamless response.

Efficient Airflow
The LS1 is ported like an overhead cam motor. Instead of curving around the push rod, the air follows a straight path down to the combustion chamber.

Long-Life Belts
The serpentine accessory drive belt is designed to last up to 100,000 miles. There are no adjustments required, ever. (Maintenance needs vary with different uses and driving conditions.)
