Porsche's R&D chief says that the upcoming Macan will be different than the Audi Q5 since "everything has been modified."

The upcoming Porsche Macan is scheduled for an unveiling at the 2013 Frankfurt Motor Show next September and even though it will based on the Audi Q5, the company’s R&D chief Wolfgang Hatz promises that “everything has been modified”, adding that changes have been made to the “engine, transmissions, suspension”. He also said that “Audi can’t believe what we’ve done”.

This will be the first model in Porsche’s modern lineup to be offered with 4-cylinder engines but these won’t be available at first. One of the possible 4-cylinder engines is a 2.0-liter turbocharged gasoline unit with 220 hp (164 kW). The hotter Macan S is expected to get a V6 3.6-liter naturally-aspirated gasoline engine with 295 hp (220 kW). Other potential engines include a 2.0-liter TDI with 190 hp (142 kW), a 3.0-liter V6 TDI with 250 hp (186 kW) and the Macan Turbo variant with a twin-turbo V6 3.0-liter gasoline that generates 370 hp (276 kW).

Hatz added that “Audi should have no fears” regarding the risk of stealing customers away from the Q5 because “the customers are so different.”
