The automotive industry is pushing for increased efficiency at the expense of V8-powered, tire-shredding muscle cars and sleeper cars. Don’t worry, though; if your mind and wallet crave eight cylinders, explosive throttle response, and space for a whole family, you still have options in 2023. Check out a few of the best new V8 sleepers on the market, like the 2023 Chrysler 300C and BMW M5. 

What is a sleeper car?

| Stellantis

A sleeper car is a subtle, unsuspecting sedan or hatchback with ample power and sports car-beating speed. Contrary to popular belief, a sleeper can be a factory application or custom build. However, in some cases, these family-friendly cars pack throaty factory V8s, like the now-discontinued Chevrolet SS

In fact, some of the most unhinged eight-cylinder sleeper cars promise rubber-roasting power in an unsuspecting package.

BMW M5600 hp/ 553 lb-ft$111,895

What is the difference between a Cadillac CT5-V and a CT5-V Blackwing?

The 2023 Cadillac CT5-V packs a 360 horsepower 3.0L twin-turbocharged V6, while the CT5-V Blackwing conceals a 668-horsepower supercharged 6.2L V8. As a result, the Blackwing will hit 60 mph in as little as 3.4 seconds with an automatic transmission. 

However, many sleeper car fanatics will want the Blackwing’s party piece: an optional six-speed manual transmission. It’s really the only way to conduct the Caddy’s musical mill. Frankly, it’s a familiar recipe in performance Cadillacs like the now-extinct CTS-V: take a refined, buttoned-up aesthetic and add silly amounts of power and performance equipment. 

How much does an SRT Hellcat cost?

A 2023 Dodge Charger SRT Hellcat Widebody starts at $85,250 for the flared-fender V8 sports sedan. Better yet, the SRT Hellcat Widebody packs a 717-horsepower supercharged 6.2L V8, enough to make it one of the most potent new sedans on the market. 

However, the Charger’s days are numbered; the 2023 model will be the nameplate’s swansong sedan. Sure, the SRT Hellcat’s broad, muscular platform might not be as subtle as a Chrysler 300C. Still, its four-door application, sinister little badges, and thunderous pantomime make it a serious sleeper car.

Is the Chrysler 300 HEMI fast?

A Hemi is a famous V8 engine like this Dodge Challenger Scat Pack Shaker and Chrysler 300C.

The last 6.4L HEMI Chrysler 300, the 2023 300C, develops the same 485 horsepower as the Dodge Charger R/T Scat Pack. As a result, the limited-run 2023 Chrysler 300C can hit 60 mph in about 4.4 seconds on its way to a 12.8-second quarter mile. 

Unfortunately, like the R/T Scat Pack, Chrysler’s last 6.4L V8 sleeper car is a limited edition. Chrysler will produce just 2,000 for the U.S. market, with an additional 200 heading to our Canadian neighbors, per Car and Driver

How much does C 63 AMG cost?

The 2023 Mercedes-AMG C 63 starts at $83,000 for the S Coupe and $91,050 for the drop-top S Cabriolet. Still, while other V8-powered sleepers stop at straight-line heroics, the C 63 is taut in the corners and weighs a staggering 463 lbs less than a Dodge Challenger SRT Hellcat Widebody. 

Better yet, with 503 horsepower on the taps, the handsomely styled two-door Mercedes-AMG is just as ferocious as more flamboyant members of the sports car family. The result? A C 63 S will sprint to 60 mph in around 3.8 seconds, as quick as a much lighter C7 Corvette Stingray. What’s more, 2023 is the last year for fans to pick up a V8-powered sleeper car; next year will see the C 63 packing a more potent 2.0L turbocharged four-cylinder engine.  

What is the 0 to 60 mph of a 2023 BMW M5?

A red 2023 BMW M5 uses its V8 to hustle its sleeper car dimensions down a city street.

The 2023 BMW M5 channels the volcanic power of its twin-turbo 4.4L V8 with a balanced chassis and grippy all-wheel drive (AWD) system. The four-door V8 M5 will sprint to 60 mph in just 2.8 seconds, as fast as a new Chevrolet Corvette Stingray

Consequently, the sleeper sedan segment has no better example of a gentleman bare-knuckle boxer hiding in a three-piece Tom Ford suit. Of course, at $111,895, the M5 is on the pricier side of the 2023 market for V8-powered super sedans.
