Ward's 10 Best Engines is an annual list of the ten "best" automobile engines available in the U.S. market that are selected by Ward's AutoWorld magazine. The list was started in 1994 and has been drawn every year since then. Engines must be available in regular-production vehicles on sale in the U.S. market no later than the first quarter of the year. To be eligible, the engine also must be available in a vehicle with a base price of no more than $54,000 (for current 2007 list). During a 2-month testing period, Ward's editors evaluate each engine according to a number of objective and subjective criteria in everyday driving situations – there is no instrumented testing. The selection takes into account power and torque output, noise, vibration and harshness (NVH) levels, technical relevance and basic comparative numbers. Each engine competes against all others.
