Alpina BMW B5 Bi-Turbo 2010The single-cylinder step-down (EZA) is accompanied by a tone nothing short of spectacular, as each shift harbours a deeply sonorous back-pressure burble. The advantage versus the typical timing retardation are noticeably quicker shifts, and improved thermo-dynamic efficiency due to reduced exhaust temperatures as well as lower fuel consumption. Depending on the load on the transmission, the injection of fuel into a given cylinder is interrupted for a fraction of a second, creating the required reduction in torque that the automatic transmission needs for the up-shift. The innovative single-cylinder step-down (EZA), specially developed by Alpina for the B5 Bi-Turbo allows for super quick up-shifts in just milliseconds, in spite of the high torque.
In Sport mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The 700Nm of torque means the Alpina BMW B5 Bi-Turbo excels at gliding along at low speeds in a high gear with minimum revs, benefiting both consumption and comfort. The blend of eight speeds and plenty of torque makes for unparalleled comfortable gear changes with no noticeable interruption to the delivery of power - only the accompanying acoustics and the dynamic rev counter provide feedback as to the workings of the transmission. With Alpina's philosophy the guiding credo, our engineers have spent thousands of development and test hours ensuring that no other performance automatic transmission comes close to providing this level of both comfort and sportiness. Adapted and tested in cooperation with ZF, the advanced SWITCH-TRONIC 8-speed sport automatic transmission sets a new benchmark.
