New BMW X5 reinvented with Neue Klasse design and EV option

As with those low-slung executive models, the new SUV's platform is an evolution of the Cluster Architecture (CLAR) that has underpinned all of the Munich firm's larger models over the past decade. Using the same fundamental structure for ICE and EV derivatives of a car can lead to technical compromises that in particular dent the electric version's performance and packaging.

But while BMW has introduced bespoke EV and ICE platforms for smaller models, it says the larger platform used for the X5 is versatile enough to accept multiple powertrains without compromise.

This means that all versions can be built on the same line, enabling BMW to respond flexibly to changes in market demand for each without any drop in output. This is particularly important in the large-SUV segment, which is proving slower to transition to electric power - especially in the EV-sceptical US, which has historically been the X5's biggest market.

Big stats for electric X5

Despite using a different architecture from that of the iX3, the electric X5 is equipped with the same 'Gen6' cylindrical battery cells, 800V charging hardware and latest-generation motors as its smaller sibling, so it offers on-paper performance attributes that are more than competitive with rivals.

Crucial to that is a huge, 140kWh battery pack - the largest yet fitted to a production EV in Europe – which enables the 2890kg iX5 to offer 497 miles of WLTP-certified range. That almost matches the iX3's headline-grabbing 503-mile range, despite the iX5 weighing half a tonne more.

The increase in capacity has been achieved largely through the use of taller individual cells, which are 25mm higher than those in the iX3, at 120mm.

The 140kWh battery can charge faster than almost any other EV in Europe, at 450kW, and is capable of bi-directional charging. It is fitted to the range-topping 60 xDrive, which will be the first iX5 variant on sale, but BMW is likely to introduce a smaller-capacity and cheaper battery option down the line.

The 60 xDrive has a 325bhp motor at the rear and a 245bhp motor on the front, giving punchy combined outputs of 570bhp - more than today's full-fat X5 M performance flagship - and 593lb ft. That's enough to shift the iX5 from 0-62mph in just 4.7sec, making it as quick off the mark as the outgoing plug-in hybrid, and on to a top speed of 130mph.

There is no word yet on a single-motor, rear-driven derivative, which could trim the price while significantly boosting range, as is the case with the iX3.

Six-cylinder engine lives on

True to form, the X5's combustion powertrain line-up revolves around BMW's trademark 3.0-litre straight-six engines.

BMW UK won't take the petrol version, with the mildly hybridised 'B58', but it will continue to offer a non-plug-in option in the form of the 40d xDrive, which uses a twin-turbo diesel six to drive both axles.

Also a MHEV, the diesel sends 282bhp and 479lb ft to both axles through a ZF eight-speed automatic gearbox. It is good for 0-62mph in 6.2sec, a top speed of 143mph and combined efficiency of up to 40.4mpg. Crucially for a big diesel SUV, it can tow up to three tonnes - sufficient for horse boxes, caravans and car trailers.

After the diesel comes the petrol plug-in hybrid. It uses a set-up familiar from the outgoing PHEV, combining the six-cylinder engine with an 18.7kWh battery under the boot floor and a 194bhp electric motor ahead of the gearbox.

There have been tweaks to the battery chemistry and electric motor, and the system has been retuned with the aim of improving refinement, but combined outputs are unchanged at 483bhp and 516lb ft - and performance is roughly in line with its predecessor's.

BMW claims 0-62mph in 5.0sec, a top speed of 150mph and combined consumption of between 67.3mpg and 88.3mpg for the lower-powered 50e xDrive. The battery is good for a claimed electric range of up to 63 miles.

Unlike the outgoing car, the X5 PHEV will also be offered in M-fettled M60e xDrive form, with outputs boosted to 604bhp and 590lb ft to trim the 0-62mph time to 4.5sec and nudge the top speed to 155mph.

Charging for both plug-in hybrid variants is still limited to 11kW top-ups, while rival PHEVs such as the Range Rover Sport and Mercedes GLC can fast-charge at 50kW-plus.

Top of the Klasse

The new X5 is the largest model yet to adopt BMW's Neue Klasse design language, which was introduced with the iX3 and i3. Visually, it makes the new model a complete departure from the X5 it replaces, despite the semi-familiar underpinnings.

The form language and defining signatures are familiar from the X3 - including the minimalist, monolithic silhouette, muscular rear haunches, wraparound front light panel and distinctive vertical kidney 'grilles' - which will be a shared characteristic of all BMW SUVs going forward.

However, the X5 introduces a raft of bespoke cues that mark it out. Most obvious of these are the double-X LED light graphics that, says BMW, make it "instantly recognisable during both day and night". These distinctive cross-shaped clusters incorporate the headlights, daytime-running lights and indicators. They can be switched at the press of a button for the iX3's simpler diagonal arrangement.

Notably, the M60e xDrive PHEV will be the first model to feature M division's new trademark yellow headlights, which were introduced on the M Concept Neue Klasse that was revealed earlier this month. Wheels will be 21in as standard on all cars, while the range-toppers will be available with 23in rims for the first time.

Inside, the new X5 is similar to the iX3, with the cockpit dominated by the unusual diagonal central touchscreen and a full-width panoramic driver display at the base of the windscreen.

The bulk of the switchgear is shared too, as is the unusual multifunction steering wheel. Unlike the existing Neue Klasse models, however, the X5 adds the option of a second touchscreen for the front passenger - with an array of streaming and entertainment apps to keep them entertained when on the move.

While it uses an evolution of the older CLAR architecture, the iX5 has been equipped with the same electronics and software stack as the iX3, which means it uses BMW's 'Heart of Joy' control unit to offer what the firm calls "unrivalled driving dynamics" via rear-biased, four-wheel torque vectoring and lightning-quick suspension, throttle and braking interventions.

All versions of the iX5 will ride on air suspension (the system will be available as an option on the ICE car), and active anti-roll bars and rear-wheel steering will be among the chassis-enhancing options offered.

Hydrogen iX5 on the horizon

The iX5 Hydrogen is set to be launched in 2028, powered by a fuel cell powertrain developed under a partnership with Toyota.

The system will be evolved from that which powers the experimental FCEV version of the outgoing X5, but with significant advances in packaging, power density and performance. The current system produces a combined 396bhp and offers 313 miles of range from its pair of 700-bar hydrogen tanks.

Chief among the upgrades is a new 'flat storage' design, which compresses the tanks themselves into a container that's the same size as the battery in the pure-electric iX5 - enabling the two cars to be built alongside each other and offer the same interior space.
