The optional 6.7-liter turbodiesel V8 is rated at 400 hp and 800 lb-ft of peak torque. To meet the latest air emissions standards, the diesel engine uses an after-treatment system that requires replenishment of diesel exhaust fluid (DEF) about every 7,500 miles. Both engines are mated to a six-speed automatic transmission. Properly equipped, the F-250 Super Duty can tow up to 14,000 pounds with a conventional trailer setup. When configured for fifth-wheel towing, that figure jumps to 16,700 pounds.
