10 Sports Sedans That Can Be Easily Modified Into Supercar Killer

Sports sedans are specifically designed to be like their sports car alternatives, but with more practicality and comfort in mind. Modern sports sedans are easily as fast, or even faster, than today’s sports cars, and some even give supercars a run for their money.

Sports sedans are great! They combine the ease and practicality of a 4-door sedan with the ferocious speed and power of a sports car, all while maintaining the comfort and roominess of the previous body style. BMW was the first to try this, and it paid off. Not only did they create one of the coolest segments in the auto market, but they also dominated it with each iteration of their famous M5. While the Mercedes-Benz S-Class sets the standard for all luxury sedans, the M5 is the standard for the sports sedan.

While sedans themselves are already ridiculously good, many aftermarket companies have always wanted to know what they could actually make them do, resulting in modified sports sedans that could easily outrun modern supercars in a drag race, not to mention on a track. With that, here are ten sports sedans that can be easily modified into supercar killers.

10 BMW M5 (Evolve)

The current BMW M5 is a monster of a car as it is able to keep up with and easily put many sports cars to shame, even giving supercars a run for their money. The M5 CS is an even more aggressive version of this, thanks to its tuning and slight increase in power.

While factory tuning gets results, aftermarket tuners can really bring out the car’s potential. For example, British tuner Evolve has squeezed an incredible 1,000 hp out of the current M5, making it much faster than the standard version, even beating a Porsche 911 Turbo S in a drag race.

9 Mercedes-Benz E63 AMG (Brabus)

Brabus is known for his absolutely ridiculous melodies. From something as subtle as a restored 280SL Pagoda and 190E to the utter insanity that is the V12 E-Class Brabus Baron and Brabus Rocket 900. One of their more “normal” models is the Brabus 800, an E63S AMG based creation.

The 800 gets the typical Brabus body treatment, including more aggressive bumpers, side skirts and spoiler, but the 788-hp 4.0-liter twin-turbo V8 is also tuned. Unfortunately, these mods don’t come cheap, with a Brabus 800 costing more than twice what the original E63S AMG cost. A good lot of money.

8 Audi S8 (ABT)

ABT is a tuner of mainly VW-based products, mostly Audis. They create faster and even more attractive versions of the already amazing S and RS cars. An example of this is the RS6R, a hardcore version of the fantastic RS6 Avant.

Another model they work their magic on is the S8. While the stock car isn’t slow by any standards, ABT took it upon themselves to improve it. As a result, the S8 makes 700 hp and received some subtle styling tweaks, including prettier wheels. Now the ABT S8 is ready to take on V12 BMW 7 Series and S-Class models.

7 Cadillac CTS-V (Hennessey)

The Cadillac CTS-V is a brilliant American sports sedan that rivaled the likes of the BMW M5 and Mercedes-Benz E63 AMG. The last generation of the CTS-V had the 6.2-liter supercharged V8 from the C7 Z06 corvette. The base car produced 640 hp and 630 pound-feet of torque.

Hennessey got hold of the CTS-V and offered their now famous HPE packages, notably the HPE850 and HPE1000. These increased the power to a staggering 850 hp and 830 lb.ft or 1000 hp and 966 lb.ft respectively. This gives the Hennessey CTS-V more straight line speed than the McLaren 765LT.

6 Jaguar XE S (SVO)

The Jaguar XE was the British brand’s competitor to the BMW 3 Series, Audi A4 and Mercedes-Benz C-Class. It had some good 4-cylinder engines, including a diesel, and a supercharged V6 which is also used in the F-Type.

Luckily for everyone, Jaguar’s in-house tuning division, special vehicle operations, got involved and created the most powerful Jaguar sedan in the company’s history: the XE SV Project 8. It featured the XFR-S’s 5.0-liter supercharged V8, boosted to 592 hp. The XE SV Project 8 is definitely an amazing tuned sports sedan that easily outperforms a supercar on a track.

5 Mercedes-Benz CLS63 AMG (Brabus)

The previous generation Mercedes-Benz CLS63 AMG was a true muscle sedan in a superbly styled body. He had the ability to be fast, comfortable, and fierce all at the same time. Brabus then expanded the dial-up even further and created the Brabus Rocket 800 CLS.

Brabus has taken the 5.5-liter twin-turbo V8 out of the car and replaced it with a 6.0-liter twin-turbo V12, upped the power to 790 hp and 811 lb.ft of torque, retuned the transmission, and added some traditional Brabus trinkets to the exterior. The end result is a luxury sports sedan capable of finishing the 0-60 mph sprint in just 3.7 seconds and tops out at around 230 mph. Adequate numbers of supercars.

4 Dodge Charger SRT Hellcat (Hennessey)

The top-spec variant of the Dodge Charger SRT Hellcat is already among the three fastest production sedans in the world alongside the Bentley Flying Spur Speed. The Charger accomplishes all of this while costing less than half the price. As such, Hennessey came along and is currently offering her services to make the Charger even crazier.

The Hennessey charger is available in three packages: HPE900, HPE1000, and HPE1000 Redeye. The latter two are mostly the same apart from the Redeye’s added options and a slight torque bump over the standard HPE1000. This results in a 0-60 mph time of just 2.8 seconds and a quarter-mile time of under 10 seconds, all in a rear-wheel drive muscle car!

3 Subaru Impreza WRX STI (Tex Modification)

The Subaru Impreza, being a Japanese legend, has many tuning options available in the aftermarket. One that stands out is Tex Modify. The company often plays around with the R30 and R31 Skylines, Mitsubishi Galants and Nissan Silvia S15, but this Impreza WRX STI really impresses.

The 2.0-litre Boxer-4 was enlarged to 2.5-litres and completely rebuilt with forged pistons, polished and oiled cylinder heads, new camshafts and a massive turbocharger. The end result is a 600whp monster with a muscle car-like scoop to suck air into the larger radiator to keep things cool. This modified Impreza can easily keep up with supercars, especially when driving on Japan’s various mountain roads.

two Bentley Flying Spur (Mansory)

The Bentley Flying Spur is a beautiful sedan, both inside and out. It combines amazing luxury and ridiculous performance, all in one aesthetically pleasing vehicle. At the moment, the Flying Spur is available with a W12, a V8 and a hybrid V6, quite a variety.

For those who like to be seen a little more, Mansory offers several options and packages that will make the Flying Spur not only relaxing and luxurious, but also a true supercar killer. The Mansory Flying Spur W12 produces 710 hp and 738 lb.ft, a healthy increase from the standard car. The vehicle accelerates to 60mph in 3.6 seconds and tops out at 211mph, or almost as fast as a McLaren 720S. Not bad for a huge luxury sedan.

1 Mercedes-AMG GT 63S 4 doors (Brabus)

Finally, probably the most ridiculous modified sports sedan currently on sale is the Brabus Rocket 900, also known as the Mercedes-AMG GT 63S 4-door. The regular GT 63S 4-door is no slouch, with a 4.0-liter twin-turbocharged V8 producing 630 hp and 664 lb-ft of torque.

Brabus worked their magic and in addition to the massive amounts of carbon fiber on the exterior, they completely rebuilt the engine. The enlarged 4.5-liter twin-turbocharged V8 now produces 888 hp and 750 lb-ft of torque, sending power to all four wheels through Mercedes’ 9-speed automatic transmission. The Rocket 900 only takes 2.8 seconds to hit 60 mph and tops out at 206 mph. Brabus only did ten of them, but we’re glad they did.
