McLaren 650S Sprint revealed – debuts at Pebble Beach

The McLaren 650S Sprint arrives to hit the track The arrival of the McLaren 650S in February (and the end of the 12C, unless it’s being replaced by the McLaren 625C) meant, in all probability, that the various hardcore versions of the 12C would be replicated for the 650S. We’ve already has the new McLaren 650S GT3 at Goodwood this year, and now we get the car that fills the gap between the 650S and GT3 version for McLaren owners to take to the track – the McLaren 650S Sprint. The 650S Sprint – which we assume replaces the 12C Sprint – keeps the 650S’s 641bhp V8 but adds a hefty dose of track specific updates to make the Sprint more focused and with sharper responses.
