Instead of 10% more horsepower I would be impressed with 10% more miles per gallon. Who over the age of 21 really cares whether a truck goes 0-60 in 8.5 or 8.1 seconds. In the first 100,000 miles the average owner is going to spend more than $20,000 for regular gas and a 10% improvement in fuel economy would put $2,000 in their pocket instead of those of oil company executives.
