    A Viable Option? #2016

    The new #BMW-X5-40e #BMW-F15 costs the same as a xDrive40d model but which makes more sense to buy? #BMW-UK has pitched the #Hybrid-X5-40e right into the section of the 4x4 market occupied by the X5 40d… but is the part-petrol, part-electric machine a real alternative? Words: Bob Harper. Photography: BMW.

    So here it is, the first of what will be four full plug-in hybrid models that #BMW will be launching in the UK this year. The X5 is the first to get the #PHEV treatment but following closely on its heels will be the 330e (that you can read about on https://drive-my.com/en/social/stream/item/8100.html ), the 220xe and the 740e and no doubt when the new Five and Six are eventually announced both of those cars’ architecture will have been designed to allow full use of BMW’s drivetrain of choice.

    We’ve already had ‘ActiveHybrid’ versions of the 3, 5 and 7 Series but the next generation of BMW Hybrids are far more advanced than those and promise greater electric ranges and are less compromised in day-to-day use than its previous efforts. The real question that needs answering is whether one of these hybrids, and specifically this X5 we have here today, will actually suit your motoring needs? I would suggest that you’d need to sit down with a large piece of paper that will end up being covered in hastily squiggled figures to try and work out whether a hybrid or one of BMW’s already excellent diesel versions makes most sense for your specific needs.

    I have to hold my hands up and say that I approached the test of this new kid on the block with a fair amount of cynicism – a diesel X5 is a wonderful machine to drive and own and with the hybrid’s limited range and perhaps less than stellar real-world economy figures I was finding it a difficult concept that someone would actually prefer to invest in the 40e than a 40d. First impressions are certainly good however – the X5 40e in M Sport trim we have here retains the big 4x4’s handsome good looks and is still an imposing piece of kit. It’s not likely your neighbours will notice it’s a hybrid either unless they catch you charging it or clock the small 40e script on the front doors or the subtle eDrive logo sitting on the X5’s rump.


    Once I’ve clambered up into the X5, made myself comfortable and adjusted mirrors and seat to my satisfaction, I make the school boy error of assuming I’ve managed to break the X5 as pressing the starter button doesn’t elicit any sort of engine starting noises from under the bonnet. The dash pod glows nicely and I soon realise that the X5 is ‘running’ and that all I need to do if release the electronic handbrake.

    Moving off with nary a whisper from the drivetrain is always a slightly uncanny feeling, but it’s one you soon become accustomed to in the X5. Once you’re rolling it’s not an entirely noise-free environment as a certain amount of road noise and tyre roar do eventually permeate the cabin as the speed rises. Trundling around the Berkshire sub-suburban roads where speeds are generally pretty low sees the four-cylinder twin-turbo slumbering, letting the electric motor and batteries take the strain until the speed rises to around 42mph and then the internal combustion side of the equation joins the party. We seem to use the word ‘seamless’ to describe so many things these days, but it really is the right description of the way the engine kicks in and out – if I hadn’t caught the movement of the rev counter needle out of the corner of my eye I really wouldn’t have realised the engine had kicked in.


    After around 20 minutes of driving, not desperately fast, not intentionally slowly, simply keeping pace with the rest of the traffic on the road, the X5 is indicating a pretty staggering 73.9mpg. This rises and falls pretty rapidly depending on whether the four-cylinder is in play or not, and we must bear in mind that the battery was fully charged before departure, but it’s the sort of figure a diesel X5 could only dream about. The flip side of the coin is that when you use all the performance the economy plummets dramatically, but it’s worth remembering that there’s a lot of performance on offer if you use the combined might of the twin-scroll turbo four and the electric motor. Together they offer up 313hp (identical to the X5 40d’s output) and 332lb ft of torque (considerably down on the 40d’s 465lb ft) and if you ask it to, the 40e will really fly, taking you by surprise as this isn’t the sort of forward momentum you’re conditioned to expect in a car that has eco credentials. You’ll need to use the upper end of the rev-range in the 40e to enjoy the best it has to offer, but that’s no hardship as it does sound pretty good when revved hard. So, put simply, it’s pretty enjoyable to punt along, whether looking to eke every last bit of charge from the battery in the quest for ever-better economy figures, or when giving it a good old fashioned pasting.

    But how does the X5 40e seemingly manage to offer the best of both worlds? As mentioned it uses the fourcylinder turbocharged engine (in a 245hp state of tune) allied to a synchronous electric motor (offering 113hp and 184lb ft of torque) that’s housed within the eight-speed automatic transmission. It has an all-electric range of between 14 and 19 miles and that latter figure is actually the distance market research has shown to be the average journey by X5 owners. BMW UK has put together some figures for what it expects potential owners will achieve under certain driving conditions and these may well help you decide on whether or not it’s going to be suitable for your needs.


    In an urban commuting environment with journeys of up to 15 miles, BMW reckons you should be able to achieve 94mpg, running almost exclusively on electric power. For an owner using their X5 for trips of between 30 and 40 miles a day including commuting BMW expects returns in the mid-40s, typically 43-47mpg (better than you’d get with a diesel-powered X5) but over longer journeys (over 125 miles) the 40e is expected to return between 26 and 27mpg, making it less economical than a diesel model. All these figures assume you’re starting off with a fully charged battery pack, too, but as the X5 only takes two and a half hours to charge on a BMW i Wallbox (and three and a half from a standard 13amp socket) this shouldn’t be too difficult to achieve.


    However, it’s worth considering that fuel economy isn’t the be all and end all when considering one’s overall motoring cost. For instance, the difference between running a car that does 30mpg compared to one that does 40mpg is only around £380 a year if you do 10k miles per year. If one assumes the 40e returns the former and the 40d the latter you’d need to factor in road tax (free for the 77g/km 40e) while the 157g/km 40d would cost you £180… bringing the overall cost difference to just £200. So it’s as near as makes no difference. What makes a huge difference is if you intend on running one of these as a company car as the chasm in Benefit in Kind rates are significantly larger. An X5 40e will cost a 40 per cent tax payer a little over £3000 in tax whereas a 40d will be getting on for double that figure… and surely that’s a pretty large chunk of cash unless your surname’s Abramovich.


    There are some compromises in running the Hybrid 4x4, particularly if you wanted to spec a third row of seats in your X5, as this simply isn’t available in the 40e. Boot space is somewhat compromised too, and while it still has a virtually flat load bay its capacity is down to 500 litres (the 40d has 650) with the seats up, while maximum carrying capacity is down to 1720 for the 40e compared the 1870 for the non-hybrid models. Overall though I was impressed with the 40e and were my monthly company car allowance somewhat larger and I was interested in a large 4x4 it would undoubtedly be on my short list. I would be able to get virtually all the way to the office in pure electric mode, charge it for a couple of hours and return home in the same manner. The car’s energy management system would help here too. As well as the expected Drive Performance Control switch to toggle between Eco Pro, Comfort and Sport modes there’s a separate eDrive switch that allows you to tailor the use of the batteries to best effect. The default mode is ‘Auto eDrive’ which allows for electric driving up to around 40mph and focuses on the best efficiency. ‘Max eDrive’ will see the X5 running purely on electric power up to speeds of 75mph and the four-cylinder will only be awoken from its slumber should you either exceed that speed or use kick down. The last mode is ‘Save Battery’ which allows you to effectively shut off the electric motor to save the battery for when you get to an urban area later in your journey, and this would be ideal for me to switch off the electric side of the equation when I’m on the (mostly) open roads of Kent, reverting to battery power for the last congested slog into London. And if you use the satellite navigation system the car basically works all this out for you.

    It certainly won’t be for everyone, but the 40e’s combination of low running costs (depending on your driving needs), low company car tax and the fact that it’s actually a hoot to drive quickly when the mood happens to take you makes BMW’s first full hybrid a bit of a winner if you ask me. My only fear is that BMW won’t be able to make them fast enough…

    Interior of the 40e shares the same handsome architecture as other X5s.

    eDrive lets you make the most of hybrid modes; boot is smaller than regular X5 and there’s no seven-seat option.
