The Cadillac Escalade-V raises the bar for full-size SUV performance, and the first one will raise something else.

Cadillac is sending Escalade-V #001 across the auction block at the Barrett-Jackson event in Las Vegas on Fourth of July weekend with the proceeds of the sale benefiting the Pensole Lewis College of Business and Design in Detroit.

The school was originally founded as the Lewis College of Business in 1928 and closed in 2013, but reopened as Michigan's only Historically Black College or University last year.

The $149,990 Escalade-V going on sale this year is both the most expensive and most powerful Cadillac ever.

It uses a 682 hp version of the 6.2-liter supercharged V8 that's also featured in the CT5-V Blackwing sedan. With 653 lb-ft of torque it's able to accelerate the three-ton truck to 60 mph in 4.4 seconds.

General Motors has partnered with Barrett-Jackson on several charity auctions in recent years that have resulted in eye-popping prices being paid.
