505 HP Hummer H3R Concept Is Bringing Its LS7 To The Auction Block

The V8-powered off-roader sports a 4-inch lift and 35-inch tires

If you’ve forgotten about the Hummer H3R concept, you’re not alone. However, the high-performance off-roader will be auctioned off at Mecum’s Indy Fall Special on October 5.

So what makes the H3R so special? A 7.0-liter LS7 V8 sourced from the Corvette Z06. The General didn’t even leave that stock as it’s been equipped with a custom air induction system as well as special valve and ignition coil covers. They’re joined by a larger radiator, a four-speed automatic transmission, and a locking front differential.

The 505 hp (377 kW / 512 PS) SUV looks the part thanks to a four-inch lift as well as 20-inch wheels wrapped in 35-inch Mickey Thompson tires. The latter are backed up by a high-performance Rotora braking system.

Besides the functional upgrades, the concept has a body-color grille and a unique hood with a transparent Lexan insert. The H3R is also notable for wearing skid plates, rock sliders, and a half dozen auxiliary lights. Rounding out the special features are quick-release wheel arches, a quad exhaust, and a Jerry can where the spare tire normally resides.

The upgrades to the cabin are more divisive, but there are two racing seats with five-point harnesses. The driver sits behind a Momo steering wheel and finds themselves surrounded by auxiliary gauges, painted metal accents, and carbon fiber flourishes.

Designers also gave the SEMA special a dashboard-mounted flashlight and an infotainment system with GPS navigation. While the gauges are virtually unreadable due to a map motif, the cluster suggests the concept has only been driven 1,871 miles (3,011 km). Regardless, you’d better like traveling in small groups as the second-row seat has been removed to make way for the spare tire.

There’s no auction estimate, but a little digging revealed the concept was sold by Barrett-Jackson in 2009 for $44,000. That listing also noted the vehicle is “not certified to comply with any federal, state or local laws, rules or regulations and may not be driven on public roads.”
