Do the mega-rich care much about bargains though? Probably not, but the keener pricing of the Sports Series models will allow McLaren to tap into a broader spectrum of buyers - those shopping for Audi R8 V10s and Porsche 911 Turbos.
Speaking to TMR last year, McLaren Automotive's Executive Director of Global Sales Jolyon Nash said the company hopes the Sports Series models will deliver strong sales growth.
"What the Sports Series will do is sell in a segment below the 650S and will attract new customers to the McLaren brand," Nash said.
"So if we’re selling between 3000-3500 cars a year in 2016 and 2017 we’ll be very happy, but we’ll still be very exclusive,"
Both the 540C and 570S are built on the same lightweight carbon fibre tub, and are powered by a 3.8 litre twin turbo V8 borrowed from the 650S.
However, while the 650S thumps out a huge 478kW, the 570S is detuned to 419kW. Both models push out 600Nm of torque, however, and both use the same seven-speed twin-clutch automatic transmission
Don't let the term "detuned" put you off though: the 570S is still good for a 3.2-second 0-100km/h run, and can hit 200km/h in just 9.2 seconds. Top speed is a heady 328km/h.
The 540C is no pansy either. It's got the same motor and gearbox but in a more licence-friendly 402kW and 539Nm trim, yet will still rip to 100km/h in 3.5 seconds.
