The Panamera 4 was an all wheel drive variant of the 1st Gen Porsche Panamera that was introduced for the 2010 model year. The Panamera 4 was largely the same as the Base Model, but with the addition of four wheel drive. Available exclusively in a fastback sedan body style, the Panamera 4 was powered by a naturally aspirated 3.6L V6 engine that generated 306bhp. This power was sent to all four wheels through a 7 speed 'PDK' automatic transmission. Production of the 1st Gen Panamera 4 ended in 2016, but the model series would continue in the next generation Panamera as the 2nd Gen Panamera 4.
