With high-pressure direct fuel injection, twin independent variable camshaft timing, four valves per cylinder, 9.4:1 compression and a Honeywell twin-scroll fixed-geometry turbocharger, this modest-size 2.3L pumps out 350 hp at 6,000 rpm and 350 lb.-ft. (475 Nm) of peak torque at 3,200 rpm. That amounts to an eye-opening specific output of 155 hp/L.
