When automakers talk about taking lessons learned on a racetrack and applying them to production cars, few are as serious as McLaren Automotive. The British manufacturer’s rebirth as a builder of sports cars stemmed directly from decades of circuit-racing dominance with the striking 650S that bowed at the Geneva Motor Show in 2014.

Sharing only its name with the wild McLaren F1 of two decades prior, the 650S paired a carbon-fiber chassis with active aerodynamics and a twin-turbo V-8 engine. A year later, McLaren took an even bigger step forward with the 675LT, the first McLaren since the F1 GTR nearly 20 years prior to bear the “Longtail” nomenclature. The 675LT amplified what McLaren learned developing the 650S. Focused on track racing, the 675LT upgraded every functional item from its 650S sibling. Its upsized carbon-ceramic brakes bring the car to a halt even faster, while special 10-spoke alloy wheels, weighing almost 1.8 lb less than those fitted to the 650S, help reduce unsprung weight. Additional use of carbon fiber sliced the curb weight even further. In short, McLaren took a scalpel and sharpened it.

A year after the 675LT debuted, McLaren added an open-top spider version with a folding hardtop that allowed for sunbaked sprints to 60 mph in under three seconds.

The 675LT spider offered here is one of 500 examples produced. Finished in Special MSO Bourbon paintwork and complemented by Carbon Black upholstery, it is striking to behold. The McLaren is optioned with $23,468 in MSO touches, including carbon-fiber wipers and mirror arms as well as the exterior and interior carbon-fiber upgrade pack for $10,690 and $6,270, respectively. Showing only delivery miles, 60 at the time of cataloguing, it is truly in as-new condition and ready for top-down, open-road motoring at its most exciting.
