Firstly the M5’s engine – a V8 4.4 litre capacity one – is smaller than the V10 5.0 litre engine in the previous M5 model, but is equipped with two turbochargers to compensate for this. These turbochargers, which utilise the twin scroll system specifically developed by BMW, are positioned between the cylinder banks of the engine. What this means is that torque of 501lb is available even at 5,750 rpm, compared to the maximum 383lb available at 6,100 rpm in the previous M5 model.

Furthermore the new M5 model is more financially and environmentally friendly thanks to greater fuel efficiency. The fuel consumption is reduced to 28.5 mpg, which represents a 30% reduction on that of the previous M5 model. In addition the car has an 80-litre tank, rather than 70 litres, which means that you can expect to be able to make 400 miles at a time before needing to refuel.

The car is styled with as great a degree of subtlety as can be expected from a big car, although compromises with the appearance are necessary in order to accommodate performance improvements. For example, below the front grille there are three large air intakes, which are not particularly aesthetically pleasing, but which are essential in order to provide air to cool the engine and brakes. The internal space provided is good, with plenty of room for four or five people, plus luggage, making it suitable for families.

The overall performance is superior to that of other cars in the BMW 5-series. However there are some issues in this area, with the car having a propensity towards over-steering, requiring the driver to be able to read the road surface excellently, while the relentless speed of the car can make traction challenging even on a dry road. The other big downside of the car is the price tag: the current cost of the M5 is £73,040 – putting it outside the price range of most.
