2017 BMW X3 and X3 M performance model – the latest spy photos

The third-generation BMW X3 has been spotted testing again offers the clearest places in the exterior design yet.

The video below shows a quad-exit exhaust the muscular bumper and roof spoiler, and a six-cylinder engine note can be heard, suggesting that this latest X3 car development is a high-performance variant.

BMW officials are understood to be considering the development of an X3 M model, which should produce 425bhp from the same turbocharged 3.0-liter in-line six-cylinder engine used in the latest M3. Such a car would allow BMW to compete against the Porsche Macan Turbo and the upcoming Mercedes-AMG GLC63. This latest video suggests that the car is now in the testing phase.

The X3 M to sit up over a X3 xDriveM40i M Performance, which has also been spotted testing (in the video below). That model is due to arrive after the regular 2017 model in 2018.

The X3 xDriveM40i will be powered by BMW’s twin turbo 3.0-liter, six-cylinder engine, which also features the new 7 Series. Our sources say that the model will be accompanied by a diesel variant running a version of the version of the BMW incisive 376bhp triple-turbo 3.0-liter in-line six-cylinder engine as the X5 M50d.

As for the rest of the next-gen X3 range, spy pictures show that the car’s overall shape looks slightly restyled compared to the previous model, although look to have longer rear doors and a new glass house, with the longer rear quarter windows. This suggests a slightly longer wheelbase compared to the 2810mm of its predecessor.

The new range X3, known internally under the code name G01, and will receive a cabin of a higher category with a larger infotainment screen on the top of the dashboard. This should come with the latest version of BMW’s iDrive system.

The spotted development of the cars have less heavily raked rear windows – a development that suggests BMW may be trying to give the X3 more than the capacity of the trunk over his rival, the Audi Q5.

Below, the new X3 is meant to receive a revised high-strength steel platform, with a modified double wishbone (front) and multi-link (rear) suspension. BMW sources also say that the new SUV will be getting a new electrical system that will “open up new directions in security systems and connectivity options”.

The same base and the electrical system will also support the second generation of the X4, which is set to appear in 2019.

The engine line-up for the new X3 is set to include a range of upgrade four-cylinder and new six-cylinder direct-injection petrol and common-rail diesel unit. A six-speed manual gearbox will be standard with a selection of four-cylinder engines, while a new ZF-produced nine-speed automatic transmission with the latest fuel-saving technology is likely to be matched to all the other engines.

BMW is also planning four-cylinder models with rear-wheel-drive; these will be sDrive models. However, the majority of the new X3 line-up will continue to be the standard, four-wheel drive xDrive models.

Autocar has been told the most frugal new X3 – a manual six-speed successor to today sDrive18d execution of a revised common rail injection system among other things you can get with a combined use of most of 56.5 mpg.

A model BMW insiders say that is likely that will be part of the new X3 line-up is a frugal X3 xDrive35e. Brother for the new X5 xDrive40e, the new plug-in petrol-electric hybrid has been conceived around the same driveline hardware as 330e, which appears at the beginning of next year.

The new X3 will continue to be produced alongside the X4, X5, X6 and the upcoming X7, BMW Spartanburg factory in South Carolina, UNITED states.
