If you thought the SIERRA Echo was impressive, The SIERRA R-SPEC doubles down to produce 306+ peak HP in the same 1500 lb chassis — delivering an astounding 4.8 Lbs : 1 HP power-to-weight ratio that compares to a $500,000 supercar (up to the 120 mph top speed of course.) Hypercraft’s race-proven EV technology ensures g-forces that most drivers have yet to experience. And despite this level of performance, it’s equally shocking just how efficient and maintenance-free this motorsports contender actually is — bringing ownership costs down to brakes and tires. Fair warning on the tires though, it’s quite effortless to leave some rubber on the road.
