2009 Porsche Cayenne Hybrid

2009 Porsche Cayenne Hybrid

Porsche’s upcoming hybrid ute will deliver more than 400 pound-feet of torque.

Two years ago at the Frankfurt auto show, Porsche announced it had begun work on a hybrid Cayenne program, but the company has remained quiet since then, except to tell us it has remained partnered with VW on the SUV’s development. However, Porsche recently broke its silence and gave us a few more details about what we can expect from its new hybrid SUV, which is on track for a 2009 launch.

What we know is that a compact, 34-kW electric motor in the Cayenne hybrid will slot between its 3.6-liter V-6 and the six-speed automatic transmission, a series configuration that Porsche claims is more compatible with the Cayenne’s platform. The company also says the setup is more fuel efficient and flexible in terms of the hybrid system management, which Porsche claims will allow the vehicle’s performance to remain, well, Porsche-like. By adding electric power to the 290-hp, direct-injection V-6, maximum torque rises from 273 lb-ft to over 400 at 1800 rpm for the hybrid. That part sounds good, but all the hybrid components will add significant weight to the already bloated Cayenne, so we’ll have to wait to see what affect this has on not only acceleration but Porsche hallmarks such as handling and braking as well.
