The Jaguar-Land Rover group is going to replace petrol and diesel V6s with inline-sixes, an old-time favorite architecture.
The introduction of new engines will replace the Ford-sourced units as JLR expands the Ingenium modular family of powertrains as Autocar reports. The straight-six design is essentially coming from adding an extra two cylinders to the four-cylinder Ingenium unit, with the capacity set to 3.0-litres for both petrol and diesel options.
JLR is following a similar strategy with BMW on the matter, using 500cc per cylinder with the plan to also include the launch of three-cylinder 1.5-litre units down the line. The British manufacturer will reveal their four-cylinder petrol Ingenium unit towards the end of the year.
The first cars to benefit from the new engines will be the Jaguar XE, XF and F-Pace as they share the same D7a platform, with JLR planning to use it also in future Land Rovers.
The straight-six configuration use fewer moving parts and weigh less than the equivalent V6s, making them more fuel efficient and cheaper to build, despite their inherent packaging issues.
