Aside from high-compression engines, the Skyactiv technology package includes lightweight body and chassis units, as well as automatic transmissions that combine a multiplate clutch and a torque converter.
The Explorer Sport shares the carlike body-chassis unit found on the 2012 Explorer, but instead of that model's 290-horsepower V-6 and EcoBoost 4-cylinder engines, the Sport gets a twin-turbocharged EcoBoost V-6 that, according to Ford, generates at least 350 horsepower.
Racing director Eric Boullier said: "We know that one fix or upgrade won't provide a significant upturn in performance, so we're united in our continued efforts to bring further gains to both chassis and power unit, in terms of both reliability and outright performance, step by step".
Technical director James Allison - who joined in September 2013, and had no input on the 2014 car at the conceptual stage and little on its design at all - says that "in pure lap time, the gains are almost equal chassis to power unit".
Beneath the covers there have been a raft of developments on both chassis and power-unit - all aimed at creating a car that is safer, more efficient, more reliable and ultimately faster".
One of just 32 units built, chassis No 6107 commands what may prove to be a modest pre-auction estimate of $12m to $15m.
The theory of turning of the adaptive bodies of mountain tandem-wheeled motor vehicle chassis intended as power units in small farms, is offered.
The unit-body chassis and potent 80-100 horsepower twin cam engine were both technical milestones, and the cars were available in multiple body styles, from sedans to coupes and convertibles.
Later, Abiteboul added: "We need to work together to understand our issues, both within the power unit and the chassis.
Additionally, the unit's rigid frame and beam chassis helps to reduce vibration and a low-leakage R-core transformer minimizes the interference of digital noise.
