To fabricate its most recent like red apple-creation, Ferrari initially destroyed a flawlessly decent auto. In changing the beyond any doubt footed F12berlinetta thousand tourer into the quick and-free, pinnacle bothering F12tdf, Ferrari engineers deconstructed the dependability that is intrinsic in the F12's long wheelbase, its significant weight, and its high polar snippet of latency with respect to mid-engined autos. The front tires developed in width from 255 millimeters to 285 millimeters, a forceful arrangement supported turn-in and horizontal grasp, and—with no change to the back tire width—a whimsical, oversteering creature was conceived. One Ferrari case engineer portrayed the collaboration obtusely: "Initially, we spoiled the auto."
With the suspension suitably squirrelly, designs connected the brand's first utilization of back wheel guiding to dial in simply enough steadiness to make the auto reasonable and unsurprising. Ferrari calls the subsequent bundle Passo Corto Virtuale, or virtual short wheelbase, and it shrivels the F12tdf's 107.1-inch wheelbase and 3600-pound control weight to Miata-such as sensations. OK, perhaps the F12tdf doesn't drive very that little and agile, but it more than compensates with the uncanny precision that $490,000 buys. All newF12tdf worms its way into your psyche with delicate, light steering that is direct, immediate, and unforgiving. Spin the steering wheel too fast or too far and the rear responds just the same, rotating too fast or too far. Get it right, though, and the car darts where you look with the rear tires faithfully following the front end in a tight, tidy arc. It’s ironic that the steering feels like the most special of the F12tdf’s specialties, because while Ferrari massaged the F12’s engine, transmission, suspension, brakes, and aerodynamics for the F12tdf program, the hydraulically assisted steering system is the one component left unchanged.
The electric motors that steer the rear wheels at up to two degrees in either direction come from ZF, but Ferrari engineers performed all of the software calibration to ensure the system works in harmony with the electronically controlled limited-slip differential, the magnetorheological shocks, the traction control, and the stability control. As you click the steering-wheel-mounted manettino drive-mode selector from Sport mode to Race to CT Off (traction control off), the car’s agility swells. Neutral is the wrong word, though, because neutral implies a car that can be provoked to understeer as readily as it oversteers. The F12tdf’s front tires only plow when you do something truly stupid.
Modern rear-wheel-steering systems, including those in the big-dog Porsche 911s, typically countersteer relative to the front wheels at low speeds to improve agility and steer in the same direction for greater stability at elevated velocities. Ferrari claims its adaptation doesn’t need to countersteer the rear wheels; the natural behavior of the car is sufficiently agile. Instead, the Italians need only the enhanced stability to keep the tail from overtaking the front of the car in corners. Ferrari's past track extraordinary, the apropos named 458 Speciale, can move any driver toward a saint with its wonderful parity and unflappable cool. That mid-engined auto's responses will compliment you into trusting everything you might do is a perfect execution of vehicle-motion hypothesis. The F12tdf is far less sympathetic. It requests more concentrate, more ability, and more regard. In kind, it conveys legitimate fun that is both phenomenal and uncanny in an auto with this much power and this much grasp.
Consider it a demonstration of exactly how alive and inebriating the frame is that it's taken approximately 550 words to get around to the 6.3-liter V-12, in light of the fact that the dramatization of unleashing each of the 769 torque is man's most noteworthy tribute to the inside ignition motor. At full throttle, it roars like a thousand celestial trumpets introducing into auto fellow paradise as the revs wind up like a groin rocket's.
The F12tdf marshals an extra 39 pull and 11 lb-ft of torque over the standard F12 with the assistance of another air-channel box, reconsidered consumption plumbing, and a bigger throttle body. Strong lifters supplant water powered tappets. The subsequent weight decrease permits Ferrari to add more valve lift to the admission cam profile and to raise the rev limiter from 8700 rpm to 8900 rpm. Variable-length admission runners use extendable trumpets inside of the admission plenum to contract or extend the runner length for streamlined wind current. In the F12tdf, Ferrari utilizes only two particular positions—short and long—but future cars may take advantage of the fact that the position of the trumpets is continuously variable between the boundary conditions. Shorter gear ratios throughout the seven-speed dual-clutch automatic transaxle are augmented with quicker shift times. We project a 2.8-second blast to 60 mph on the way to a 10.8-second assault on the quarter-mile. The always-on nature of the big-displacement, naturally aspirated 12-cylinder engine demands a delicate right foot on corner exit, but the pedal obliges with long, linear travel. When it’s time to reverse thrust, a brake pedal with just as much fidelity activates a carbon-ceramic braking system borrowed from the LaFerrari hypercar. Ferrari intends the F12tdf to be a car that owners will drive to the track, at the track, and back home from the track. But in readying the F12 for regular track service, the suspension has lost some suppleness. Even with the dampers set to their more compliant mode, the F12tdf skims over humps in the road like a skipped rock. In city driving, the F1 dual-clutch transmission isn’t as velvety as Porsche’s or McLaren’s gearboxes, particularly in off-throttle downshifts. Overall, though, the F12tdf remains a civilized road car. While lighter microsuede replaces leather and carpets have been removed altogether, Ferrari still fits a radio, navigation, and air conditioning.
Ferrari stripped a total of 243 pounds from the F12. A chunk of that weight comes from reducing the amount of glass on the car by tapering the rear window and shrinking the rear-quarter windows until the transparent section is no larger than an iPhone. Carbon fiber is now used for the door skins inside and out, plus the front and rear fascias. And while the rest of the body panels are still aluminum, the roof and the A-pillars are the only pieces that carry over from the F12. The bevy of dive planes, spats, and spoilers increase downforce to more than 500 pounds at 124 mph. While they’re added for functional purposes, the cooling and aerodynamic changes also create something visually striking. The righteous louvered fenders bulging around the rear tires are both an homage to classic Ferraris and a carnal suggestion of what the car is capable of. Ferrari may have taken one step backward to start work on the F12tdf, but its finished product is miles ahead of the F12 in driving excitement.
