The LaFerrari is powered by a 6.3-liter V-12 working in conjunction with a KERS-style hybrid setup. Two electric motors are featured, one mounted to the gearbox and aiding the engine by sending drive to the rear wheels and the other used to take some of the load off the engine by powering auxiliary devices. Peak output of the system is 950 hp, or enough for 0-60 mph acceleration in less than three seconds. Ferrari built 500 LaFerrari coupes and 210 LaFerrari Aperta convertibles. The last of each body style were built for charity auctions.

No estimate on any of the cars were given but with the fanaticism of collectors, especially those with a penchant for Ferraris, final bids in the seven figures is likely. As a guide, a pre-production LaFerrari prototype sold for $2.25 million in 2017. That prototype was the one customers used to configure their own cars.

Mecum’s auction in Monterey runs Aug. 18-20. There will also be a 2014 prototype for a Ferrari F12 TDF going under the hammer. Other highlights include a rare McLaren Sabre, a 1973 Porsche 911 Carrera RS 2.7 previously owned by Paul Walker, and a stunning 1936 Duesenberg Model J.
