Porsche is set to launch a range-topping 370bhp-plus Turbo-badged vehicle for its Macan lineup, effectively establishing a new performance 4x4 niche when it arrives at UK showrooms in October 2013. Porsche is optimistic that the Macan Turbo will establish a niche for itself as the fastest and most dynamic model in its class, especially with the absence of dedicated performance variants of competitors like the BMW X3 and Range Rover Evoque.
Porsche anticipates that the Macan Turbo will achieve the same success as it did with the larger Cayenne. The range-topping Macan would be the first car to be equipped with Porsche’s new twin-turbocharged V6 petrol engine, which remains a secret until now.
The twin-turbo V6 was developed in-house at Porsche’s R&D centre in Weissach, Germany, and is agreed to have a 90deg vee and a 3.0-liter capacity.
It’s expected to be a version of the 3.6-litre V6 that would be installed on the entry-level Cayenne and Panamera models. With the use of twin sequential Borg Warner turbochargers, an air-to-air intercooler system and other internal revisions such as a compression ratio that’s lower than that of the normally aspirated 3.6-litre engine, its peak power and torque now have an output of 370bhp and 400lb ft.
This stands for an increase of around 80bhp and 105lb ft compared to the non-turbo 3.6. The Macan is based on the Volkswagen Group’s next-generation large front-wheel drive and four-wheel drive platform, dubbed MLB.
The outcome is that the new V6 could be mounted longitudinally and all four wheels are driven through a Torsen torque-sensing differential that’s engineered by Audi and modified by Porsche.
The rear axle comes with electronically controlled torque vectoring for the rear wheels in order to boost turn-in and cornering grip. Porsche is available with transmissions that include a standard seven-speed manual (which is developed from the latest unit in the 911) or an optional seven-speed, dual-clutch PDK automatic (which was also derived from the 911).
