PEBBLE BEACH, Calif. — General Motors' innovative V12 concept engine, called Northstar XV12, showcases several advanced technologies in a fuel efficient, V8-like package.
This all-new high-technology, high-output 12-cylinder powerplant, featured in the 2002 Cadillac Cien mid-engine concept car, is a 60-degree, all-aluminum dual overhead cam (DOHC) four-valve engine. It displaces 7.5 liters and produces 750 horsepower (560 kW) and 450 lb-ft of torque (610 Nm), yet is packaged in the size of a V8, and able to deliver excellent fuel economy. The engine has integrated advanced technologies for the future developed by GM Powertrain's Advanced Engineering, and assembled in a compact package that GM engineers refer to as "small on the outside, big on the inside."
The Northstar XV12 represents a unique combination of a nod to the past and a glimpse of the future.
"The Northstar XV12 provides a realistic look at what could power an assault on the high-end, premium automotive segment," said Fritz Indra, GM Powertrain executive director of advanced engineering. "At the same time it showcases a wealth of new technologies under development at GM Powertrain, many of which will eventually find their way into GM engines of all shapes and sizes."
GM historically has had a vision to provide unmatched power, refinement, exclusivity and technical excellence in its powertrains. When GM's Cadillac division was solidifying its standing as the "Standard of the World" in the 1920s and 1930s, it did so powered by notable V12 and V16 engines.
