2014 McLaren P1 steering wheel

Performance-wise, the P1 should be properly epic. But everything is made better by go-faster buttons, and McLaren put two of them on the P1′s F1-inspired steering wheel. The buttons control F1-style boost functions: IPAS (Instant Power Assist System) and DRS (Drag Reduction System). When activated, IPAS instantly unleashes full electric power—so all 177 horses. Push the DRS button, and the P1′s rear wing drops to a lower angle, reducing drag by 23 percent. The wing returns to its original, draggy position when the button is released or if the driver hits the brakes.

At the rate it’s going, McLaren won’t even need to reveal the P1 in Geneva—we can practically gather up all the individual details and put the puzzle together ourselves. You can bet it’s a puzzle the boys at Ferrari are scrambling to solve, too, given that their upcoming F150—the Enzo replacement—also will feature a gas-electric hybrid powertrain with a seven-speed dual-clutch transmission. Maranello’s creation will have four additional cylinders but two fewer turbochargers. Game on.
