Win a 761-HP RENNtech-Built 2018 Mercedes-AMG GT + $25,000 Cash

The build: RENNtech's big-turbo C190

Urban Exotics' headline prize is a 2018 Mercedes-AMG GT coupe that has been through RENNtech's full R3 program: larger turbochargers on the 4.0-liter hot-V V8 for a claimed 761 hp and 632 lb-ft, plus Ohlins dampers, a racing brake package, carbon aero with vented fenders, and — telling you what this car was built to do — a roll cage and harness setup. Power goes rearward through the GT's seven-speed automatic transaxle. The operator lists 18,070 miles, while the official rules cite roughly 25,000 — a gap worth confirming, since it affects value. Notably, neither the page nor the rules says which AMG GT this started as — base, S, C, or R.

Why it matters

RENNtech is not a sticker-kit tuner; the shop was founded by AMG North America's former technical director, and its big-power M178 builds are among the few with genuine credibility. A caged, 761-hp C190 is a rare commission. Be clear-eyed, though: the cage and harnesses make this a track tool more than a grand tourer, the donor trim is undisclosed, and heavily modified cars live and die by their documentation. The bundled $25,000 check helps, because the tax bill is yours.

The fine print worth knowing

Entries run June 8 through September 15, 2026 (11:59:59 p.m. ET), with the drawing on or about September 25 by an independent administrator. Every $1 spent on Urban Exotics merch earns one entry, and quick-entry bundles run from $50 (1,250 entries) to $300 (24,000 entries), capped at 100,000 entries per person. There is a free mail-in route — a hand-printed 3x5 card to the administrator in Pittsford, NY, one per envelope, worth 50-75 entries depending on how you read the rules' contradictory text. Open to US residents 18+ (19+ in AL/NE) with a valid driver's license; the page excludes Rhode Island and Minnesota, and the promotion is void in US territories. No cash alternative to the car is offered, and the winner covers title, registration, and all taxes.
