What Car? says...
Technically, the 540C is McLaren’s entry-level car, although that classification seems more than a little unfair. While it’s certainly the cheapest car the company offers, it still gets a 3.8-litre twin-turbocharged V8 like almost every other McLaren currently on sale.
In the 540C, it develops a mighty 533bhp – enough for a 0-62mph time of just 3.5sec and a top speed of 199mph. They may sound like supercar numbers, but McLaren classifies this as part of its Sports Series, which includes the 570S and 570GT.
