You want sports-car performance without selling your soul to a six-figure price tag. This roundup shows how familiar four-door sedans can deliver blistering straight-line speed and everyday practicality that challenge the Porsche 911 — often for less than half the price.
Expect to find surprising sleepers and mainstream models that mix luxury, power, and value so you can get 911-level acceleration without the 911 sticker shock. Browse the list to see which sedans—ranging from high-performance Audis and BMWs to electric and muscle contenders—fit your budget and driving goals.
Audi RS5 Sportback
You get a five-door liftback that mixes practicality with muscle, powered by a strong twin-turbo V6 and all-wheel drive.
It often matches or beats 911 acceleration in real-world tests while costing far less, especially used; check current pricing and comparisons like this Car and Driver review of the RS5 Sportback.
Interior tech and daily comfort make it easier to live with than a pure sports car, and its hatch adds real cargo flexibility.
Expect sharp handling but a different driving character than the rear‑engine 911.
BMW M3 Competition
You get a throat-clearing twin-turbo inline-six that launches hard and holds pace with much pricier sports cars.
Adaptive suspension and all-wheel drive give you grip and composure, so straight-line sprints feel controlled rather than frantic.
Used examples often undercut new 911 prices by a wide margin, making performance more attainable if you shop carefully.

Tesla Model S Plaid
You’ll feel the Plaid’s instant torque the moment you mash the accelerator; it launches sub‑2‑second 0–60 mph runs in ideal conditions.
That straight‑line fury comes from a tri‑motor setup and over 1,000 horsepower, letting it outrun many sports cars on the drag strip.
The cabin doubles as a roomy daily driver with tech and range that make it practical beyond straight‑line bragging rights.
If you want Porsche‑beating straight‑line speed for far less than a new 911, the Model S Plaid is one of the best ways to get it.
Jaguar XE SV Project 8
You’ll find the Project 8 is a rare, track-focused sedan that punches well above its price compared with many sports cars. It packs a 592-hp supercharged V8 and was built in a 300-unit run, so examples are uncommon and sought after.
Expect a stiff, purposeful ride and aerodynamic upgrades made for laps, not comfort. See a current auction listing for one available now on Bring a Trailer.
Dodge Charger SRT Hellcat
You’ll feel the charger’s 700+ horsepower shove you back in the seat, turning daily commutes into brief drag-strip thrills. The Hellcat mixes four-door practicality with raw V8 performance, so you get family-hauling space without surrendering speed.
You can find used examples at much lower prices than new, making them one of the few ways to beat a Porsche 911 in straight-line pace for less cash. Check listings like this Used Dodge Charger SRT Hellcat for Sale Under $50,000 Near Me to start your search.
Lexus GS F
You’ll notice the Lexus GS F brings a big‑displacement V8 where many competitors use turbo fours or sixes. It’s older tech, but that 467‑hp V8 delivers strong, linear power and a satisfying exhaust note you can feel as much as hear.
You get a roomy, well‑appointed cabin that’s more comfort than track austere. Prices on used examples often land well under half the cost of a new Porsche 911, making the GS F a compelling value for straight‑line muscle and daily usability.
