2024 Dodge Challenger SRT vs 2027 BMW M3 Competition xDrive: Power-Meets-Top-Speed Test

DragGap comparison data

The table below summarises the key modelled figures from DragGap's simulation. Each value is an estimated output from a consistent simulation model, not a measured result.

| Metric | 2024 Dodge Challenger SRT | 2027 BMW M3 Competition xDrive | |---|---:|---:| | Output | 671 kW / 900 hp | 597 kW / 800 hp | | Mass | 1580 kg | 1700 kg | | Drivetrain | Rear-wheel drive | All-wheel drive | | 0-60 mph | 1.64 s | 2.18 s | | 0-100 km/h | 1.70 s | 2.25 s | | 1/4 mile | 9.05 s | 9.36 s | | 1 km | 17.06 s | 16.84 s | | Top speed | 294.3 km/h | 318.3 km/h |

Two very different ideas of straight-line performance

The Dodge Challenger SRT is the paper champion on output and weight. Its 671 kW (900 hp) engine hauls a relatively light 1580 kg body through a rear-wheel-drive layout, which gives it the strongest power-to-weight ratio of the pair. The BMW M3 Competition xDrive counters with 597 kW (800 hp) and a heavier 1700 kg mass, but spreads that power across all four wheels.

That difference in philosophy shows up immediately in the numbers. Where the Challenger leans on raw output to launch, the M3 leans on all-wheel traction to deploy its own substantial power more efficiently once the wheels are turning.

The simulated race: sprints versus the kilometre

The short-distance picture belongs to the Dodge. In the DragGap model the Challenger SRT records a 0-100 km/h estimate of about 1.70 s and a quarter-mile estimate of roughly 9.05 s, both quicker than the BMW's modelled 2.25 s and 9.36 s. Off the line and through the first quarter, the lighter, more powerful rear-driver is the faster car.

Over the full kilometre the roles reverse. The BMW M3 Competition xDrive posts a 1 km estimate of about 16.84 s against the Challenger's 17.06 s, and its 318.3 km/h top-speed ceiling comfortably outpaces the Challenger's 294.3 km/h. Carry the race to the end of the run and the DragGap model has the BMW taking the win by roughly 0.22 s, crossing about 13.2 metres ahead.

All of these are simulated, modelled projections of relative pace — not measured real-world results.

Off the line: raw power versus all-wheel traction

Launch behaviour is where the two cars part company most clearly. The Challenger SRT's early lead comes straight from its superior power-to-weight ratio, but that advantage is delivered through the rear wheels alone, so the model's projected short-run dominance is a traction-management exercise. The BMW's all-wheel drive lets it put its 597 kW down more evenly, which is part of why it is so close over the quarter-mile despite the horsepower deficit.

A straight-line simulation captures how each car would ideally deploy its power, but real-world grip, surface and tyres add a layer of variables that any model necessarily simplifies.

Which one should you choose?

If your priority is a savage launch and the quickest first few hundred metres, the Challenger SRT is the pick — its 0-100 km/h and quarter-mile estimates lead the matchup. If you want the car that keeps pulling to an enormous top speed and takes the longer-distance win in the DragGap model, the BMW M3 Competition xDrive is the answer.

Both are enormous, comfortable performance sedans; the choice comes down to whether you value short-burst brutality or an all-wheel-drive package that sustains pace right to the far end of the kilometre.
