Which were the fastest-accelerating vehicles of the 77 we tested in 2018? Below we look at the cars that stunned us when it came to accelerating off the line. Note that this list is based on test figures we gathered during our standard, rigorous road-test procedure (rather than simply times claimed by the respective manufacturer)...

5. Mercedes-AMG GT R: 3,77 seconds

720S

The Mercedes-AMG GT R was not only one of the fastest cars we took round the track in 2018, but also one of the fastest in a straight line (and we’re sure it'd be even quicker off the line if it had a bit more traction at the rear). With 430 kW being delivered from its twin-turbo 4,0-litre V8, the GT R registered a 0-100 km/h time just a touch away from its claimed 3,6 seconds.

4. Audi TT RS Quattro S tronic: 3,74 seconds

TT RS

Despite costing almost R1 million, the TT RS is the cheapest car on this list by some margin. With its 2,5-litre five-pot delivering 294 kW to all four wheels through Audi’s Quattro system, this pocket rocket was able to achieve a 0-100 km/h time that would give many a supercar a run for its money...

3. BMW M5 xDrive M Steptronic: 3,43 seconds

M5

BMW’s latest M5 has become a bit more sophisticated thanks to an xDrive system that directs the V8's 441 kW to all four wheels. Although the power output is the same as the previous Competition model, its acceleration time has improved thanks to that extra traction...

2. Mercedes-AMG E63 S 4Matic+ 9G-tronic: 3,40 seconds

E63 S

The previous E63 was available with the brand's 4Matic system, but this version never made its way to South Africa. Thankfully, with this generation, 4Matic+ is standard fitment ... and that's made us realise what we've been missing out on in terms of straight-line speed. The M5 rival bags a slightly faster 0-100 km/h time thanks to a 450 kW twin-turbo 4,0-litre V8 similar to the one in the GT R also on this list.

1. McLaren 720S Coupe: 3,09 seconds

720S

The top spot on this list is occupied by the highest-rated and most expensive car we tested in 2018 (and the only non-German here). The 720S coupé uses a twin-turbo 4,0-litre V8 sending a whopping 527 kW to the rear axle. The fact the engine sits in the middle (and that the vehicle itself doesn’t weigh all that much) means the 720S has no problem accelerating to 100 km/h in double-quick time.
