Dodge Viper ACR (Gen V) · 2016–2017
The Gen V ACR is the final and most extreme Viper: an 8.4-litre naturally aspirated V10 — the largest-displacement engine in a modern production sports car — hand-built in Detroit with a full Extreme Aero package generating over 1,700 lb of downforce. It closed out the Viper line as the production-car track-record holder, setting lap records at 13 US circuits, and its aero-limited 177-mph top speed reflects a car built to corner rather than cruise.
