Both cars record the same 0-100 km/h time of 3.7 seconds. 2026 Porsche Taycan 4S has the higher listed output at 537 hp; 2026 Audi RS3 Sportback is rated at 407 hp, a difference of 130 hp. The torque figures follow 2026 Porsche Taycan 4S at 710 Nm and 2026 Audi RS3 Sportback at 500 Nm. These figures describe straight-line potential only; they do not establish braking performance, ride quality, steering response or durability under repeated hard use.
Range, battery, charging and efficiency
Range and energy-use figures are either not shared by both cars or not directly comparable across these powertrain types.
Dimensions, cargo space and towing
2026 Porsche Taycan 4S provides the larger quoted cargo volume: 405 litres versus 282 litres, a difference of 123 litres. 2026 Porsche Taycan 4S is 582 mm longer overall. Exterior size is not a benefit by itself: a longer body may create useful room, but cargo shape, rear-seat space and ease of parking still require a physical inspection.

2026 Audi RS3 Sportback has the lower listed starting price at $65,500, compared with $108,200 for 2026 Porsche Taycan 4S. 2026 Porsche Taycan 4S leads in more of the shared headline fields, but that is not a universal verdict: a buyer should weight price, performance, range and utility rather than simply count category wins. The assessment is based on the specifications shown here; it is not presented as a two-car road test.
