Kevin Hart Unveils Dark Knight Buick Grand National With Cadillac V6 Power

Unfortunately, that’s about all MagnaFlow had to say about the custom engine. It doesn’t mention the car’s HRE wheels or the unique “Dark Knight” lettering. The press release didn’t mention the interior, but you can see that it mimics the original but with a modern twist.

We don’t have confirmed engine specifications, but if we had to guess, the team borrowed an engine from a Caddy CT4-V Blackwing. It’s powered by a 3.6-liter twin-turbo V6 that produces 472 horsepower and 445 lb-ft of torque. Given Kevin Heart’s love of high-horsepower cars, it must have been tuned up to at least 600 horses.

We’ve reached out to MagnaFlow to try and get some specifics on mechanical upgrades for this Buick and will update this article with the results.

The car is part of the “Kevin Hart Collection,” which includes a custom C1 Corvette and Hart’s Speedkore Charger.
