"PerformanceThe Eagle Vision ESi came equipped with a 3.3 liter V6 engine initially producing 150 bhp (112 kW) and rising to 162 bhp (121 kW) in the 1994-1995 models. For 1996, it lost 4 hp (3 kW), but gained 9 ft·lbf of torque. The TSi was factory-equipped with the more powerful SOHC 24-valve 3.5 L V6 engine producing 214 bhp (160 kW). Both engines were joined to a 4-speed automatic, but only the '96 and '97 TSi with its 3.5 had the 4-speed autostick option, with no option of a real manual transmission.
