It makes sense that the previous BMW X5 xDrive40e was difficult to sell. With only 14 miles of electric driving range available from a 12-kilowatt-hour battery, it may not have been worth the extra cost.

A turbocharged 2.0-liter 4-cylinder gasoline engine was also employed in the initial X5 PHEV. The combined output of the electric drive motor was 308 horsepower and 332 pound-feet of torque. That enabled it to tow almost 6,000 pounds and accelerate to 60 mph in 6.5 seconds, but BMW was aware that there was room for improvement.

Now, a silky-smooth 3.0-liter turbocharged inline 6-cylinder gasoline engine debuts with the 2021 BMW X5 xDrive45e. According to the Environmental Protection Agency, a larger 24-kWh battery is double the capacity of the 12-kWh pack in the prior model and provides a projected 31 miles of electric driving range (EPA).

The 8-speed sport automatic transmission is feeding BMW’s rear-biased xDrive all-wheel drive with a total system output of 389 horsepower and 443 pound-feet of torque.

There are three driving modes available to drivers:

  • The SUV always starts in hybrid mode, which allows for electric driving up to 68 mph as long as you don’t press too hard on the accelerator.
  • An enhancement over the previous 75 mph electric mode is the switch to all-electric driving at speeds up to 84 mph. When necessary, activate Hybrid mode by pushing the accelerator past the “kick-down” position (you’ll feel a brief resistance in the pedal).
  • Sport mode makes sure the gas engine is always operating for a thrilling performance.

Is the new plug-in hybrid powertrain flawed in any way? Yes. The new BMW X5 xDrive45e from 2021 is less effective than the X5 xDrive40e from earlier.

The EPA gave the previous X5 plug-in hybrid the following accolades:

  • 59 kWh per 100 kilometers for electric vehicles
  • Using both gasoline and electricity, 56 MPGe
  • Fuel efficiency in hybrid mode is 24 mpg.

The new X5 plug-in hybrid is rated by the EPA as follows:

  • 63 kWh/100 kilometers while using electricity
  • Electric mode achieves 50 MPGe, then hybrid mode.
  • in hybrid mode, 20 mpg

Is the new X5 xDrive45e’s increased power, smoothness, and driving range worth the economy trade-off? Yes, in my opinion.

Also take note that the X5 PHEV has slightly less cargo space than other X5 versions. The volume decreases by 0.8 cubic feet when measured behind the back seat. 1.10 cubic feet are lost when you fold it down.

Cons

The remarkable plug-in form of the BMW X5 hybrid, known as the xDrive45e, has an electric driving range of about 50 miles. The previous xDrive40e model only got 20 miles, so this number is far better than the normal 30 miles you get from many plug-in vehicles. The X5 plug-in competes against a number of vehicles, including the hybrid Volvo XC90, Audi Q7, Mercedes GLE, and Porsche Cayenne.

One of the best models in the lineup is the X5 hybrid. For lengthy trips, the diesel models still make a lot of sense, but the xDrive45e’s large electric range and affordable company-car expenses make it possible for it to be surprisingly inexpensive to operate. Keep it plugged in every night, like with all PHEV vehicles, and it should theoretically be able to achieve the 200mpg+ fuel economy claims.

In our experience, even in freezing weather and on the freeway, you can expect to travel roughly 38 miles entirely on electricity. Expect much more if you commute frequently in town, which is pretty astounding for such a big, heavy SUV. Being a large six-cylinder petrol, efficiency will suffer a little bit once the engine starts. Expect less than 30 mpg if you drive with the battery entirely discharged, so it’s not the best option if you can’t frequently recharge.

But the X5 is more than simply an inexpensive vehicle to operate. The engine is so smooth and powerful that you would not even notice the additional running costs associated with using it. Despite the additional weight from the battery setup, the X5 xDrive45e is just as enjoyable to drive as other versions of the vehicle, so on the proper roads, you might even describe it as enjoyable.

Additionally, it has a comfortable ride thanks to the standard air suspension, even on large 21-inch wheels. It’s just a simple cruiser that can also entertain if you want it to, along with outstanding finesse.

It also provides plenty of room for all passengers and their luggage, albeit you can’t have this version with seven seats because of the space that its batteries occupy. Of the two trim levels available on the X5, xLine makes the most sense, as its 19-inch wheels give a slightly better ride than the M Sport’s 20s, but many buyers prefer the more aggressive styling of the latter model, which costs several thousand pounds more. If you want a seven-seat electrified car, you’ll have to look to the Volvo XC90 T8 or the Tesla Model X.

SUV BMW X5 plug-in hybrid: More power and nearly twice as much electric range

The second version of the German automaker’s mid-size plug-in hybrid SUV is the 2021 BMW X5 xDrive 45e. It received a more than double electric range upgrade over its predecessor on Wednesday and also boasted more power.

The estimated EPA range will improve to 30 miles from the current generation X5 plug-in hybrid’s 14 miles.

That’s largely because the battery pack has a larger 24-kilowatt-hour capacity. That’s a sizable battery pack for a plug-in hybrid—it was the same size as the battery pack in the first Nissan Leaf and much larger than the 12-kWh pack in the previous generation vehicle.

The bag, which is hidden beneath the floor, does take up some cargo room. According to BMW, the X5’s cargo capacity is down 0.8 cubic feet with the back seats up and 1.1 cubic feet with them folded down.

Also receiving an upgrade is the internal combustion engine is the 2021 X5 plug-in hybrid. The 2.0-liter turbocharged inline-4 has been replaced with a 3.0-liter inline-6. The larger powerplant utilizes a single electric motor and an 8-speed automatic transmission to deliver power to all four wheels.

Compared to the X5 plug-in hybrid’s previous iteration, power has increased substantially. The overall system output has increased by 81 hp and 111 lb-ft to 389 horsepower and 443 pound-feet of torque.

According to BMW, the X5 will accelerate from 0 to 60 mph in 5.3 seconds, which is 1.2 seconds faster than the previous model. A maximum towing capacity of 7,200 pounds was also stated by the automaker when using the optional factory-installed hitch.

The top speed in electric mode is electrically limited to 84 mph, up from the previous limit of 70 mph. The X5’s top speed in hybrid mode is electronically capped at 130 mph, or 146 mph with the performance tires that are an option.

The other new plug-in hybrids from BMW have the dual goal of increasing electric range while also enhancing acceleration.

Even if owners consistently charge it, it is still unclear whether the X5 will get better gas mileage than a non-hybrid.

The 330e plug-in hybrid car, unveiled in late March, has less mpg than a non-hybrid 3-Series but longer electric range than its predecessor, similar to the X5.

But during a recent test drive of the 2020 BMW 754e plug-in hybrid, we observed better fuel economy than the EPA rating.

Review of the BMW X5 xDrive 45e: A Beautifully Capable Plug-In Hybrid

The X5 premium SUV is crucial to get right because it will be BMW’s second-best seller in 2019 and 2020. BMW’s financial interests would not be served by discouraging customers from purchasing something as well-liked in such a competitive market, which is perhaps why there are currently five different X5 models on the market. I’m here to explain why the 2021 BMW X5 xDrive 45e, a hybrid model, merits your attention.

In a song from the 1990s, Shania Twain sings, “Oh my goodness, you think you’re unique. Oh, you really think you’re someone else. That doesn’t really impress me.” BMWs might not impress you because you see them all the time. Because it goes on and on, it’s possible that you believe the nomenclature for the “BMW X5 xDrive 45e” is absurd (which it is) (it does). You might not like the kidney grilles and giggle at the somewhat bucktoothed appearance.

Because of how I felt, I understand. But after a week of driving this vehicle, all of my misconceptions vanished. Poof.

Multiple modes

The X5 xDrive45e’s computer brains decide how and when to blend the electric motor and the engine while the vehicle is in hybrid mode. The X5 can travel 68 mph (109 km/h) in this mode only on the electric motor. The BMW performs admirably in this mode as well (and with a battery that has some charge remaining in it); the EPA rates it at a combined 50 mpg (4.7 L/100 km). That’s 6 mpg less than the previous hybrid X5, but the 2021 model weighs almost 400 pounds more at 5,672 lbs (2,573 kg) and features a 40% more potent engine. Therefore, this decline is not unexpected. At a combined 20 mpg (11.6 L/100 km), things become somewhat thirstier if you completely run out of battery power.

Finally, a Sport mode constantly engages the gasoline engine and recharges the battery as you drive. (The feature also performs the standard functions of Sport mode, such as increasing steering weight, stiffening the air suspension, and so forth.) On a winding road or a racetrack, an X5 xDrive45e won’t challenge an X5 M, but as we highlighted in the evaluation of the latter, the hybrid rides better and is more affordable.

In fact, the $65,400 X5 xDrive45e will frequently end up being less expensive than the X5 xDrive40i that isn’t a hybrid because it is eligible for the full $7,500 IRS plug-in vehicle tax credit (which is based on battery capacity). When you combine that with a plug-in vehicle’s significantly higher fuel efficiency and cheaper maintenance expenses, the plug-in X5 seems to be the best option among the available X5 models in terms of value.

How is the BMW hybrid engineered?

A combustion engine and an electric motor are both components of a plug-in hybrid vehicle (PHEV). Each one is competent to drive the car on their own. Regenerative braking is the energy source for plug-in hybrids, but they may also be plugged in to recharge the battery.

How far can a hybrid BMW X5 travel?

Range of the BMW X5 plug-in hybrid is assessed by the EPA to be 31 miles on electricity or 400 miles overall. Lithium-ion battery for the BMW X5: 24.0 kWh/ 68.0 Ah

Does the hybrid BMW X5 charge as it travels?

To get the most performance and power out of your plug-in hybrid car, we strongly advise charging the battery. All-electric driving will be restricted without recharging, and the power reserves for the eBoost feature will be significantly diminished. BMW advises routine overnight charging for maximum efficiency.

BMW plug-in hybrid vehicles also offer on-the-go charging. The plug-in hybrid can recover some energy while braking through regenerative technology. Additionally, the Battery Control Mode feature allows for charging to occur while traveling. By using the electric motor as a generator, this mode continuously maintains the high-voltage battery charge at the desired level or increases it to the preset value. In this manner, for instance, it is feasible to employ Battery Control Mode during a highway trip to safeguard or even boost the electric power reserves so that a later urban route can be driven entirely electrically and without any local emissions.

Your PHEV will still get you where you need to go even if you don’t have time to charge it. Automatic switching to the BMW TwinPower Turbo engine occurs when the battery is completely depleted.

Does the BMW hybrid self-charge?

You may enjoy all the financial advantages of a hybrid without needing to charge your vehicle. While you’re driving, the electric battery charges itself, and the motor is employed to improve fuel efficiency.

The motor regains power when you break, giving you more miles for your money while emitting fewer tailpipe pollutants.

The ideal way to start driving electric is with a self-charging hybrid vehicle. They’re also perfect if you want to go electric but don’t have access to convenient charging stations because you can top off the battery without plugging in.
