Ferrari's virtual short wheelbase creates a kick-ass car in the real world.
To build its contemporary pink-blooded introduction, Ferrari first ruined a perfectly exact car. In remodeling the certain-footed F12berlinetta grand tourer into the fast-and-unfastened, apex-hounding F12tdf, Ferrari engineers deconstructed the stability that’s inherent in the F12’s lengthy wheelbase, its great weight, and its high polar moment of inertia relative to mid-engined vehicles. The the front tires grew in width from 255 millimeters to 285 millimeters, an aggressive alignment boosted turn-in and lateral grip, and—and not using a exchange to the rear tire width—a fickle, oversteering monster turned into born. One Ferrari chassis engineer described the group’s work bluntly: “First, we screwed up the car.”
With the chassis certainly squirrelly, engineers carried out the logo’s first use of rear-wheel steerage to dial in only sufficient stability to make the automobile attainable and predictable. Ferrari calls the ensuing bundle Passo Corto Virtuale, or digital short wheelbase, and it shrinks the F12tdf’s 107.1-inch wheelbase and 3600-pound lessen weight to Miata-like sensations. Ok, perhaps the F12tdf doesn’t drive pretty that small and nimble, however it more than compensates with the uncanny precision that $490,000 buys.
The electrical cars that steer the rear wheels at up to 2 degrees in both direction come from ZF, but Ferrari engineers performed all the software program calibration to ensure the machine works in harmony with the electronically controlled restricted-slip differential, the magnetorheological shocks, the traction control, and the stableness manipulate. As you click the guidance-wheel-installed manettino pressure-mode selector from sport mode to Race to CT Off (traction manipulate off), the auto’s agility swells. Neutral is the wrong phrase, even though, due to the fact impartial implies a vehicle that can be provoked to understeer as with ease because it oversteers. The F12tdf’s the front tires only plow while you do some thing virtually stupid. Contemporary rear-wheel-steering systems, which include those within the big-dog Porsche 911s, commonly countersteer relative to the front wheels at low speeds to enhance agility and steer in the equal course for more balance at accelerated velocities. Ferrari claims its adaptation doesn’t want to countersteer the rear wheels; the natural conduct of the automobile is sufficiently agile. As a substitute, the Italians need handiest the enhanced balance to maintain the tail from overtaking the the front of the automobile in corners. Ferrari intends the F12tdf to be a car that owners will power to the tune, at the track, and again home from the tune. However in readying the F12 for ordinary track service, the suspension has misplaced some suppleness. Despite the dampers set to their more compliant mode, the F12tdf skims over humps in the street like a skipped rock. In town riding, the F1 dual-clutch transmission isn’t as velvety as Porsche’s or McLaren’s gearboxes, specially in off-throttle downshifts. General, even though, the F12tdf stays a civilized avenue vehicle. While lighter microsuede replaces leather-based and carpets had been eliminated altogether, Ferrari still fits a radio, navigation, and aircon. Ferrari stripped a total of 243 pounds from the F12. A piece of that weight comes from decreasing the quantity of glass on the car by tapering the rear window and shrinking the rear-sector windows until the transparent segment is no large than an iPhone. Carbon fiber is now used for the door skins inner and out, plus the the front and rear fascias. And at the same time as the relaxation of the frame panels are still aluminum, the roof and the A-pillars are the simplest portions that bring over from the F12. The bevy of dive planes, spats, and spoilers boom downforce to extra than 500 kilos at 124 mph. At the same time as they’re introduced for purposeful functions, the cooling and aerodynamic changes also create something visually putting. The righteous louvered fenders bulging across the rear tires are both an homage to classic Ferraris and a carnal inspiration of what the auto is able to. Ferrari may also have taken one step backward to begin paintings on the F12tdf, however its finished product is miles in advance of the F12 in using exhilaration.
