The Sentra S, SV, SR and SL are all powered by a 1.8-liter 4-cylinder engine that produces 124 horsepower and 125 lb-ft of torque. A turbocharged 1.6-liter 4-cylinder engine with 188 hp and 177 lb-ft of torque is offered in the SR Turbo and NISMO models.
With the exception of the base S model, which comes with a 6-speed manual transmission, all models with the 1.8-liter engine employ a gearless continuously variable automatic transmission(CVT). The Sentra SR Turbo and NISMO also come with a 6-speed manual transmission and offer a uniquely tuned CVT transmission with manual shift mode as an option.
Fuel economy estimates for SV, SL and SR models with the CVT are very good, at 29 mpg city/37 mpg hwy. The S with the 6-speed manual returns a slightly lower 27 mpg city/35 mpg hwy. In the turbo models, the 6-speed manual earns 26 mpg city/32 mpg hwy, while the CVT ups those figures to 27 mpg city/33 mpg hwy. The NISMO 6-speed manual earns 25 mpg city/31 mpg hwy, while the CVT gets 25 mpg city/30 mpg hwy.
