BMW’s new 2016 Track Handling package, an M Performance limited-slip diff, the M Performance package, and a smattering of varied other M parts. The engine gains 35 horsepower-pushing it to 335-while torque figures vary depending on transmission choice. Choose the manual and you simply find the full-boat 332 lb-ft, while those who decline to shift for themselves put up with a less-lusty 317. Which continues to be 17 lb-ft much better than stock. The energy gains are due to software tweaks, a revised intake, and presumably, the M Performance engine cover.
BMW claims gains of 0.2 second to 60 mph and 0.5 second for the 50-to-75 sprint. They’ve also programmed in extra exhaust burble. Talking about gas extraction, the ZHP receives a lighter exhaust system with stainless tips, too.
Outside, the ZHP is treated to front and rear carbon-fiber spoilers, more aggressive-looking rocker panels, and an M Performance rear diffuser with an expanded-metal grille. The piece de resistance, however, might be the M Performance Black Kidney grilles.
