2001 Hyundai Sonata Owners Manual

Under the hood of base models is a standard 2.4-liter four-cylinder engine making 150 horsepower and 156 foot-pounds of torque. Buyers can upgrade to a more powerful V6 or get it standard if they spring for GLS trim. This V6 is an aluminum 2.5-liter DOHC motor making 170 horsepower at 6,000 rpm and 167 foot-pounds of torque that peak at 4,000, which means power off the line can be a bit lacking.
