A single-cockpit EV powerhouse.
SIERRA Cars is a trailblazing force in ultra-performance vehicles that recently launched their all-electric ECHO line of performance vehicles. Unlike previous SIERRA Cars models, which ran internal combustion engines, the SIERRA ECHO line powered by Hypercraft is all electric and primed for consumer availability in three distinct configurations: ECHO (base model), ECHO R-Spec, and ECHO Block Edition. The ECHO line represents SIERRA Cars’ commitment to pushing the boundaries of electric vehicle technology, while maintaining the proven chassis and exclusive appeal that have defined the brand since its founding in 2018.
