A Beautifully Competent Plug-In Hybrid


As BMW’s second-strongest seller of both 2019 and 2020, the X5 luxury SUV is an important one to get right. It would certainly not be in BMW’s best financial interest to turn buyers off something this popular in such a hot segment, which is probably why there are currently five different available flavors of X5. I’m here to tell you why the hybrid one—the 2021 BMW X5 xDrive 45e—deserves your attention.

There’s a ’90s-era Shania Twain song that goes, “Oh-oo-oh, you think you’re special. Oh-oo-oh, you think you’re something else. That’s don’t impress me much.” Perhaps you aren’t impressed by BMWs because you see them everywhere. Perhaps you think the “BMW X5 xDrive 45e” alphabet soup nomenclature is silly (it is) because it goes on and on (it does). Perhaps you don’t love the kidney grilles and snicker at the rather bucktoothed look.

I get that because I felt similarly. But then I drove this thing for a week and all my misperceptions disappeared. Poof.

What Is It?

BMW introduced the X5 luxury midsize SUV in the late ’90s and its popularity ever since is undeniable. Now in its fourth generation, the current X5 maintains much of the original’s proportions and looks—from the kidney-shaped grille to the tall windows and big wheel arches. Sitting between the smaller X3 and larger X7, the X5 maintains the boxier and more traditional SUV-look that the X6 “SUV-coupe” forgoes. And within the X5 lineup itself, the xDrive 45e plug-in hybrid slots above the sDrive40i and xDrive40i and below the X5 M50i.

Introduced in early 2019, the xDrive 45e is the successor to 2015’s X5 xDrive40e. Under the hood, it has a 3.0-liter, turbocharged straight-six engine that makes a combined 389 horsepower and 443 pound-feet of torque. Over the 40e’s 2.0-liter, turbocharged four-cylinder, this marks an 81-hp and 111 lb-ft improvement. All 45es are equipped with an eight-speed automatic transmission and a rear-biased all-wheel-drive system.

The hybrid system itself has also been upgraded. The battery, which sits in the SUV’s underbody, now has a battery capacity of 24 kWh, up from the 40e’s 12 kWh. That gives this X5 variant an EPA-estimated range of up to 30 miles of electric-only driving. That’s notably twice as much as what it used to be, which we reported as a “paltry” 14 miles in our 2018 review. The 45e’s top speed when driving in electric-only mode also grows from 75 mph to 84 mph.

The X5 typically comes standard as a five-seater, though you can option it with a third row, albeit a small one. You can’t get the optional third-row seat on the 45e, however. This is likely because of the battery’s placement. There’s also an unnecessarily blingy crystal shifter knob and I feel fancy every time I drive it. Do I need a glass shifter? No. Do I love it all the same? Yes.

Driving the X5 xDrive 45e

What do you get when you combined a punchy straight-six with a hybrid powertrain? Something that gets going quickly and met my expectations while both merging on the highway and passing on country roads.

I gave the 45e a good workout, too, driving it from Austin, Texas, to Houston—162 miles away—to attend a Mecum auction the day after I got my second COVID-19 vaccination. (I woke up that morning, took stock and realized I felt fine and all of my body parts were intact, so I decided on a whim to take a drive.) A few days later, I zipped up to Dallas, 200 miles away. That amounted to hundreds of miles of highway driving, and the SUV performed beautifully.

Its three drive modes—Hybrid, Electric, and Sport—give you a chance to customize your ride. Hybrid is the mode you start up in, where the car figures out the most efficient way to use its two types of motors. In this mode, you can drive up to 68 mph in the car’s electric-only setting. Electric mode, as its name suggests, is the gasoline-free mode, where you can reach emissions-free speeds of 84 mph. Sport mode is the most aggressive, where the system more actively draws regenerative energy from the engine and braking. This mode gives the 45e the chips to sprint from zero to 60 in an estimated 5.3 seconds (that’s quicker than the new Toyota GR 86 sports car). And, of course, adaptive and individual modes can be tuned to the way you drive the vehicle.

I piloted the X5 45e as much as I could in the span of a week, running it to the grocery store, picking up my son and his friends from school, and spooling it out on the highway to get a feel for the acceleration. Braking activates the SUV’s hybrid regenerative systems, which gives it a somewhat spongy feel, but I felt confident that it was still going to stop quickly. 

The X5 xDrive 45e is pleasantly quiet to drive. Inside the cabin, I didn’t have any trouble listening to music, and the volume was calibrated to properly fill the space gradually. It’s easy to enjoy the road manners of this SUV, which gets up to speed quickly with a tweak of torque boosted by the electric motor. Merging onto highways was seamless; driving onto I-35 is no joke and other drivers will plow you right under their wheels if you’re not paying attention. Dimensionally, it feels substantial enough to hold its own but narrow enough that I didn’t sweat the concrete barriers in the omnipresent construction zones between Austin and Dallas.

Both the back seat and trunk space are ample. My 11-year-old son and two of his buddies, who are nearly my height, lounged comfortably behind me and appreciated the USB ports in the seatback. The power liftgate is divided into two parts, which I like because that means it’s not such a giant door opening in front of you with your hands full of groceries but two-thirds of the usual size. If you need more loading room, the bottom flaps out, too.

When you’re traveling, stopping for gas can be an annoyance, but I was delighted that I drove 200 miles to the Dallas area and got almost all the way back without having to fill up. Candidly, the X5 45e has a slightly smaller tank than its non-plug-in sibling (18.2 gallons to 21.9 gallons) so that’s why the 45e gets an estimated 400 miles of total range. However, it’s worth noting the base, rear-wheel-drive X5 sDrive40i—which is cheaper—gets an estimated 504 miles of total range.

Of course, range isn’t the whole story. The point of the 45e is to let you try out the electric life with 30 miles on electricity alone. For longer trips you still have the comfort and familiar option to stop at a gas station and fill up. 

Pros and Cons

Let’s go ahead and address the buck-toothed elephant in the room: the grille. Before I knew the 45e personally, I would snicker at the giant grille on this thing. Now that we know each other better, I don’t even notice it because the drive captures my attention and keeps me happy. As we discovered earlier this year, BMW doesn’t really care what anyone thinks about its designs anyway. The company calls it “bold,” we call it “over-grilled” and it comes down to personal taste whether you can live with it or not.  

Use-wise, I was very satisfied with the car. Except, for some unknown reason, the 45e kept disconnecting Apple CarPlay at random intervals. This was more than a little annoying. The brakes were slightly squishy but not so much that it was distracting. Other than that, honestly, there wasn’t much else to nitpick. 

As soon as I slid behind the wheel, the first thing I noticed was that the leather seats were incredibly cushy and the headrest well-placed and soft. Not all headrests are created equal, and some are as uncomfortable as an airline seat in coach class. That’s not true for the X5 45e; these are first-class. Walking around to the rear of the car, the top of the liftgate opens quickly while the bottom opens separately with one touch of a button, making it a simple matter to load heavier things into the back. 

BMW does a great job with details. The “experience modes” change the temperature inside the cabin, open and close the sunroof, and adjust the lighting to match your mood. The stitching and placement of buttons and knobs are thoughtful, befitting an upscale brand. 

Then we get to the price, because we’ve dinged the plug-in X5 for being expensive before. Base, non plug-in hybrid X5 models start at $60,395. Opting for the PHEV X5 automatically raises the price by $6,000, though you do get the more powerful hybrid engine and all-wheel drive as standard. Other standard features include 19-inch wheels, a 12.3-inch driver information gauge, a 12.3-inch center display, BMW’s iDrive infotainment system, navigation, Apple CarPlay and Android Auto compatibility, and BMW’s suite of standard safety features such as blind-spot detection, lane-departure warning, and frontal collision warning.

As tested, the review vehicle rang in at $81,695, including the $995 destination charge. That’s with all of the proverbial bells and whistles, including some most people will find to be completely unnecessary. There are several ways to chisel down that top-level…
