In this test we are going to look at the four hottest engines in the Chevy/GM inventory, and view both power and fuel consumption figures.

Chevrolet Corvette

First up was the new 2014 Chevrolet Corvette. Under the hood is the famous small block V-8 cranking out 450 horsepower. A 6-speed automatic shifter is available, but I had the slick shifting 7-speed manual. Either way, you can reach 0-60 mph in just over four seconds. Gas mileage was very good, showing 27 mpg on long highway trips.

The interior is all new, with better materials and workmanship. The seats are now properly done, a big leap from the garbage ones that were previously offered. Thank you!! And the price is right, with the coupe starting about $52,000. This was a convertible loaded up with goodies, so it was $69,000. Still a lot of car for the money.

Camaro SS

For those who like style, but have less to spend, there is the Chevy Camaro SS. It too has the small block, but with less horsepower at 426. The transmission is a 6-speed manual, or 6-speed automatic. The convertible has weight added on, but 0-60 comes in about 5 seconds. Gas mileage is listed at 16/24 mpg which is what I got.

This convertible was a real looker, and got attention wherever it was parked. Mine was loaded up with every option, with a sticker shock of $46,360! It's still cheaper than the Corvette.

Chevy Silverado 6.2 V-8

The engine in this truck is close to the Corvette powerplant, but is detuned to 420 horsepower for better torque delivery. The smaller 5.3 liter V-8 gets gas mileage of 16/21 mpg, while this biggie got 14 in the city, 16 in mixed, and 20 on the freeway. But if you can afford the $53,470 price tag, you won't worry about the gas bill!

GMC 2500 Duramax Diesel

We tried to get a Chevy Duramax, but ended up with the GMC version, which is really the same thing. This monster turbo diesel puts out 397 horsepower, but a stump pulling 765 ft/lb of torque. Such power isn't cheap. The motor and automatic tranny adds about $8,500 to the tab. Add another 3 grand for the 4x4, and 3 grand for double doors, and we were up to a $62,000 sticker in no time!

Gas mileage was 14 city, 16 mixed, 18 freeway cruising at 75+ mph, and at 65 mph cruising, we hit 20 mpg. This was with an empty bed. Pulling a full 9-ton load, I am told mileage is about 12 mpg, but this is better than most big gasoline engines that would be doing 8 mpg with the same cargo. This is where the diesel fuel savings come in, even if it takes a while to pay for that engine. But it's so much fun having this massive power, I think that alone is worth the extra tab.
