M5Board brings us an interesting head-to-head showdown between an Aston Martin DBS Touchtronic and the BMW M5 Touring with ESS ECU chip. Before we all jump into a flaming war about the results, let’s take a step back and lay out some facts. First off, this was a straight-line race with amateur drivers, an important element to consider.
Second, the M5 clearly had some engine modifications which could have given an edge in straight-line.
Third, the DBS has historically scored better times at Nurburgring, so this shows that the car is capable on taking the M5, if handled properly.
With these facts laid out, let’s have a look at the powerplants of these two cars. Aston Martin DBS uses a 5.9L V 12 double overhead cam engine which produces 510 horsepower at 6,500 rpm and 420 ft-lb of torque(570 Nm) at 5,750 rpm. The car weighs 3,737 lbs.
The BMW M5 Touring is powered by the same natural aspirated 5.0-liter V-10 cylinder engine as its sedan counterpart. The new M5 Touring redlines at 8,250 rpm and reaches 500 horsepower and 383 lb-ft of torque. It weighs 4,136 lbs.
