2007 Suzuki Swift vs 2007 Suzuki Swift: A Same-Model Straight-Line Showdown

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 | 2007 Swift (high output) | 2007 Swift (light) | |---|---:|---:| | Output | 92 kW / 123 hp | 68 kW / 91 hp | | Mass | 1005 kg | 965 kg | | Drivetrain | Front-wheel drive | Front-wheel drive | | 0-60 mph | 8.39 s | 8.42 s | | 0-100 km/h | 8.90 s | 8.88 s | | 1/4 mile | 16.45 s | 16.44 s | | 1 km | 30.76 s | 30.75 s | | Top speed | 161.9 km/h | 161.8 km/h |

A rare same-model, same-year pairing

Most DragGap matchups pit two different cars against each other. This one is unusual: both contenders are 2007 Suzuki Swift hatchbacks with front-wheel drive. The difference is in how they are specified. The higher-output version produces 92 kW (123 hp) and weighs 1005 kg; the lighter version produces 68 kW (91 hp) at 965 kg.

That is a meaningful output gap of roughly 24 kW (32 hp), partially offset by a lighter kerb mass of about 40 kg. Translating those numbers into a simple power-to-weight view, the high-output Swift carries around 0.092 kW per kilogram, while the lighter car manages roughly 0.070 kW per kilogram. The stronger engine gives one variant the nominal edge, but the weight saving keeps the other surprisingly close.

It is a neat illustration of how output and mass trade off against each other in straight-line performance.

Straight-line pace: the simulated race

In DragGap's simulation the two Swifts are separated by a razor-thin margin. The higher-output variant is credited with the win, crossing ahead by a modelled victory margin of about 0.02 seconds, with a finish gap that rounds to effectively zero metres. In practice that is a photo finish — two nearly identical cars separated by a sliver.

Looking at the individual estimates, the lighter Swift posts a marginally quicker 0-100 km/h time of about 8.88 s versus 8.90 s for the higher-output car, and a slightly quicker quarter-mile of 16.44 s against 16.45 s. The kilometre runs land within a few hundredths of each other as well, and both top out within a tenth of a kilometre per hour near 162 km/h. All of these are simulated projections, not measured real-world results.

The takeaway is that with such similar real-world pace the official win is decided by the model's rounding, not by any meaningful on-road advantage.

Power versus weight off the line

Both cars drive their front wheels, so there is no all-wheel-drive traction advantage to separate them off the line. That makes this matchup a cleaner test of output against mass. The higher-output Swift leans on its extra 24 kW to pull away; the lighter Swift uses its 40 kg saving to keep the gap small as both accelerate through the low gears.

With only 91 to 123 hp on tap, neither car produces torque strong enough to overwhelm its front tyres in the way a far more powerful car would, which is one reason the launch phase stays so balanced in the simulation. A real-world launch on a grippy surface would behave similarly, though real conditions — tyres, road surface, driver and temperature — would shift the outcome, which a straight-line model cannot fully capture.

Which Swift should you pick?

If a nominally faster, more powerful hatchback is the priority, the higher-output Swift is the pick — in the simulation it takes the win by the slimmest of margins. If the goal is a lighter, more efficient-feeling small car that gives away almost nothing in pace, the 68 kW variant is just as compelling, and its lower output typically brings a more modest appetite.

Because the two are so close in modelled straight-line performance, the decision realistically comes down to output preference versus weight, running costs, and what is available in the used market rather than any meaningful difference in speed.
