Drag Test Video: 2013 Chevrolet Corvette Convertible 430 hp LS3 Automatic- Road Test TV

July 10th, 2012 by Road Test TV

We recently had an opportunity to spend a week with a 2013 Chevrolet Corvette Convertible 1LT. During our week jaunt, we logged about 1000 miles and were impressed with the Corvette’s LS3 motor.  For 2013, the base price of a Corvette Convertible 1LT is $54,600.00.

 Engine: 6.2L V8 SFI engine LS3

Chevrolet’s well known and proven 6.2L LS3 small-block V8 packs a wallop for a naturally aspirated 2 valve per cylinder engine. In base form, the LS3 is rated at 430 Horsepower @ 5900 rpm and 424 lb-ft of torque at 4400 rpm with the standard exhaust system. An optional dual-mode exhaust system raises the power to 436 hp and 428 lb-ft of torque. Even though our test car was equipped with the standard exhaust, we were impressed with the way the LS3 pulled, especially from 3000 rpm all the way to its 6600 rpm redline.


• Displacement (cu in): 376
• Bore and stroke (in): 4.06 x 3.62
• Horsepower: 430 hp @ 5900 rpm
• Torque: 424 ft-lbs. @ 4600 rpm
• Block material: cast aluminum
• Cylinder head material: cast aluminum
• Valvetrain: overhead valve, two valves per cylinder
• Fuel delivery: SFI (sequential fuel injection)
• Compression ratio: 10.7:1
• Recommended fuel: premium recommended
• Drag Coefficient: 0.29 Cd
• Curb weight: 3239 lbs.

Transmission: Automatic

The only option on our test car was the 6-speed Paddle Shifted automatic transmission (RPO MYC). It’s an $1250.00 option and allows manual gear changes simply by tapping the steering-wheel mounted paddles. When the 6 speed automatic transmission is ordered, the 2013 Corvette receives a long legged 2.56 rear axle ratio. Good for cruising, but not great for acceleration tests…so we thought (more on that later).

Fuel economy: EPA 16 city/26 highway mpg:

The 2013 Corvette gets good gas mileage. That’s right, 430 hp and good gas mileage. In fact, far better than we expected. The combination of a steep 2.56 gear ratio, an equally steep overdrive transmission and an efficient engine makes for great mileage. During our week with the 2013 Corvette we took a 500 mile trip to the Florida Keys and averaged over 27 mpg on the highway as long as we kept our foot out of the throttle. That’s impressive.


Our 2013 Corvette was equipped with the base 5-spoke aluminum 18″ x 8.5″ front wheels and 19″ x 10.0″ rear wheels

Acceleration: Track Test Results

Our week with the Corvette would not have been complete if we didn’t take it to the drag strip for acceleration tests. It’s summer in Florida and we were expecting the heat and the Corvette’s 2.56 gear to hamper its acceleration; however, the Corvette’s LS3 exceeded our expectations as you can see from the results below.

0-60 mph     (sec.)    4.4    V-Box
0-100 mph   (sec.)    9.9    V-Box
60-130 mph (sec.)  12.4   V-Box

1/4-mile (sec. @ mph) 12.63 @ 113.5 – Palm Beach International Raceway 



The 2013 Corvette was a pleasure to drive. The manual top was easy to use. Acceleration was strong and gas mileage was good. Our biggest gripe would be the road noise that is transmitted into the interior.

In sum, the 2013 Corvette is a solid sports car for the money. We can’t wait to see what Chevrolet has up its sleeve with the C7 Corvette.


Basic: 3 yr./ 36000 mi.
Drivetrain: 5 yr./ 100000 mi.
Roadside: 5 yr./ 100000 mi.
Rust: 6 yr./ 100000 mi.

    get a stall best upgrade you will do to that tranny, you’ll drop between .5-.8 with just that.

    Yes, 2.56 is the stock ratio when you order the 6 speed automatic transmission.

    RPO – GM8: Rear axle, 2.56 ratio, limited slip
    1 – Included and only available with (MYC) 6-speed paddle shift, automatic transmission

    Thanks for watching!

    3.42 ratio comes with 6 speed manual transmission.

    2.56 ratio comes with 6 speed automatic transmission.

    Thanks for watching!

    12.6 thats it?…corvette needs to get to work. 2013 mustang gt does that.

    wow! that easily compares to a 5.0 mustang ,,, still trying to get used to the fact that mustangs (GT) now compare performance wise to corvettes (C6 LS3) back in 2008-2009 Corvettes were the shit but now its different, I wonder how long is the LS3 going to last in Corvettes and Camaros

    i dont know why everyone is getting so hyped up about the vett losing. they didnt build this vett for speed, they went for luxury. and all the engine is, is a stock ls3.

    Back in 05 there was an option for 3.15 gears in the auto. With less HP the car was the same speed as the current auto 7 years later….

    @nismofury I’m a ford guy but really 2013 mustang 5.0 will not do 12.6 1/4 mile.i have one best time I got 13.07and I drive 11 sec cobra.all the 12sec mustangs are modified

    This is going to be a terribly stupid question.. but how was this burnout done in automatic? he didn’t stand on the brakes so im curious….

    What is the point of this vid a stock vette doing 12.6 and what ?? That is so average it hurt to watch this.

    Nothing wrong with 2.56 gears when you have a 6 speed auto and the first gear is 4.027. That is 10.30xx in torque multiplication. Someone mentioned the 05 with the 4L65 being as quick with 3.15s is crazy because those were only a 3.06xx first gear and that is still 9.639 multiplied. If you do this for the first 4 gears, the 4 speed offer less multiplication in all 4 even with 3.15s. So much for simple math.

    You’re right Marc, the 2.56 gearing in the A6 is equivalent to an A4 car
    having 3.90 gears. The 2.73 are equal to 4.10 or better

    Now imagine what he would have run if he didn’t come off the line at idle.
    My guess is a 12.40 ish at 114+

    great job, considering you have the slowest optioned ‘vette…’vert, more
    weight, N.A. optional exhaust and auto. and you still ran what you did..any
    plans for mods 🙂
