Car & Driver said of the RX-01: "The total weight of this sleek little sportster is estimated at 2425 pounds, or 400 pounds lighter than the already feathery RX-7."
Road & Track said of the RX-01: "The engine growls at low rpm, smoothly changing to a nice baritone in midrange and into a fantastic tenor at high speeds, more than 8500 rpm, at which it pumps out 220 bhp. Low- and mid-speed torque is quite good, culminating at 159 lb.-ft. at 6000 rpm".
