2019–2026 Ultima RS LT1 Specs & Performance

The Ultima RS LT1 takes a naturally aspirated approach to the RS platform, pairing a traditional American V8 with a lightweight, rear-mid-engine chassis. Its sculpted coupe body incorporates aerodynamic features developed to improve stability and cooling at speed, while the rear-wheel-drive layout keeps the mechanical character uncompromised. Double-wishbone suspension at both ends and a Porsche-sourced manual transaxle give this two-seat supercar a focused engineering package built around driver involvement rather than electronic complexity.

For the 2019–2026 model, the 6.2-litre General Motors LT1 produces 460 hp and 465 lb·ft of torque. Its direct-injection V8 sends power through a six-speed manual gearbox, helping the car reach 60 mph in a claimed 3.0 seconds. A gearing-limited top speed of more than 180 mph demonstrates how effectively the RS combines substantial naturally aspirated power with a remarkably low listed weight of 2,050 pounds.
