The BMW M4 is another sports car with a long lineage, tracing its roots back to the BMW M3 of 1986. The M4 CS special edition takes the comfortable, practical M4 and sharpens it up with smarter suspension, more power and a bit less weight - but it’s very expensive in comparison. And while the M4’s appearance is just as divisive as when it was first released, there’s no denying that the extra carbon fibre addenda on the CS model makes it one of the toughest-looking cars on the road, as do the red pinstripes in the grilles. The interior is also more aggressively styled than the regular car, even if the resemblance is clear. Standard-fit carbon fibre bucket seats, a suede, flat-bottom steering wheel and plenty of red accents throughout the cabin mark the CS out as the range-topping model. You still get BMW’s excellent, curved, dual-screen setup on top of the swoopy dashboard, but you lose a bit of practicality with the removal of the M4’s central cupholder. Otherwise you get a pair of spacious (enough) rear seats and a useful 440-litre boot capacity - though if you need more space you can opt for your CS in M3 Saloon or Touring flavour. Around town the M4 CS is surprisingly easy to drive - so long as you leave it in comfort mode; you don’t get jolted around too much on bad roads. Motorway cruises are again, just as comfortable as a regular M4, but on a country lane the CS really comes alive. The 3.0-litre, twin-turbocharged inline-six engine produces 550hp in CS guise, sending you from 0-60mph in 3.4 seconds. That’s not much faster than the standard M4, but the CS’s charm is the way you can hammer down a twisty road.
