There is no verified, source-backed top ten of 2023 sports sedans in the available material. Four models have enough documented detail to compare: the Mercedes-AMG C 43, Cadillac CT4-V Blackwing, Genesis G70 and BMW M3. This guide explains what makes each a candidate, how to choose among them, and why the evidence does not support calling them a definitive ranking—or filling out six more entries by guesswork.
How to read a 2023 sports-sedan shortlist
“Best” depends on what a driver values: a manual gearbox, strong output, a performance-oriented chassis, or a sedan that also suits regular road use. Sports sedan can cover luxury performance trims, sport-oriented near-luxury models and track-focused variants, but those categories are not interchangeable. A meaningful comparison should identify the trim and model year and weigh intended use alongside engine output and transmission.
The four cars below are documented candidates, not a ranked top four. Car and Driver’s 2023 sedan roundup is a broad sedan list, not a sports-sedan-only top ten. Its descriptions of the G70 and M3 provide editorial context, not an official sports-sedan ranking.
Four documented candidates
| Model | Documented powertrain details | What the available evidence says |
|---|---|---|
| 2023 Mercedes-AMG C 43 Sedan (U.S.) | Mercedes-Benz USA describes a hand-built M139l engine, a nine-speed AMG SPEEDSHIFT MCT transmission, AMG Performance 4MATIC with rear-biased torque distribution, standard rear-axle steering and adaptive damping. | Its original U.S. announced starting price was $59,900 in April 2023; this is historical MSRP, not a current used-car value. Mercedes-Benz USA announcement |
| 2023 Cadillac CT4-V Blackwing | Cadillac lists a 3.6-liter twin-turbo V6 rated at 472 hp and 445 lb-ft. The brochure gives a 0–60 mph time of 3.9 seconds with the available automatic transmission. | The acceleration figure is specifically tied to the available automatic; it should not be read as a result for every transmission configuration. 2023 Cadillac brochure |
| 2023 Genesis G70 | Car and Driver says an available powertrain makes 365 hp. | The publication praises the G70’s pricing and handling in its broad 2023 sedan roundup. That is an editorial assessment, not a standardized comparison or official rank among sports sedans. Car and Driver’s 2023 sedan roundup |
| 2023 BMW M3 | Car and Driver describes the base rear-wheel-drive M3 at 473 hp with a six-speed manual; the M3 Competition is rated at 503 hp and pairs its engine with an eight-speed automatic. | These are review-reported trim specifications; the base and Competition versions differ in both output and transmission.

Which of these candidates fits your priorities?
For a manual transmission
The documented manual option is the base rear-drive BMW M3, which Car and Driver describes with 473 hp and a six-speed manual. The M3 Competition is a distinct choice, with 503 hp and an eight-speed automatic. Do not assume a specification for one trim applies to the other.

For a documented acceleration figure
The CT4-V Blackwing has the clearest directly stated acceleration number in these sources: Cadillac’s 2023 brochure lists 0–60 mph in 3.9 seconds when equipped with the available automatic transmission. That single figure does not establish how it compares with every configuration of the other cars.
For a mix of performance hardware and everyday use
Mercedes-Benz’s description of the C 43 identifies equipment relevant to its driving character: adaptive damping, rear-axle steering and all-wheel drive with rear-biased torque distribution. Those specifications alone do not establish how comfortable or refined it is in daily driving, so a buyer should assess the particular car and equipment in person.

For value and handling context
Car and Driver’s roundup specifically praises the G70’s pricing and handling and notes its available 365-hp powertrain. The source does not provide a directly comparable model-year price table for all four candidates, so this is useful editorial context rather than proof that the G70 is the least expensive or best value.

A defensible ranked list requires the same basic checks for every entry: exact model year and performance trim, engine output, transmission and drivetrain choices, and evidence about the car’s road or track character. Comparable original prices can help, but they must be kept separate from current used asking prices. Reliability, running costs and present-day availability need their own credible, current evidence; none can be inferred from horsepower or a historical MSRP.

The documented sources do not establish a complete set of ten candidates or comparable evidence across ten cars. Naming six additional models and assigning them ranks would make the list look comprehensive without showing why those cars belong or how they compare. For a 2023 car, also distinguish original specifications and announced pricing from the condition, equipment and price of any used example now for sale.
