The Car That Refuses to Choose a Side
In 1999, BMW did something that made the purists wince. It built an SUV. Not just any SUV - a tall, heavy, all-wheel-drive thing called the X5. They refused to call it that, of course. BMW invented the term "SAV" (Sports Activity Vehicle) because "SUV" sounded too much like a truck, and BMW does not build trucks. It builds driving machines. Even tall ones.
Twenty-five years and over 2.2 million X5s later, the formula is still working. The X5 has become the BMW people actually buy - the one that pays for the M division's tire-shredding indulgences. And in 2024, the plot thickened. BMW replaced the xDrive45e with the xDrive50e, adding 94 horsepower and ten miles of electric range in a single stroke. The result? A vehicle that can silently glide through city streets on electrons alone, then wake its 3.0-liter inline-six and demolish a mountain pass before lunch.
This is not a compromise. This is a power move. The xDrive50e pairs BMW's legendary B58 turbocharged inline-six with a fifth-generation eDrive electric motor for a combined 483 horsepower and 516 lb-ft of torque. That is more power than the original E39 M5. More than a Porsche 911 Carrera from a decade ago. And it does this while offering an EPA-rated 38 miles of all-electric range - enough for the average American commute, both ways, without the gasoline engine ever stirring from its slumber.
"The X5 PHEV occupies the sweet spot between range anxiety and petrol indulgence. It is the Switzerland of powertrains - neutral, efficient, and secretly holding all the cards."
The engineering is clever in that distinctly Bavarian way. The electric motor is tucked inside the eight-speed automatic transmission housing, an arrangement so compact you would never know there is a 25.7 kWh battery pack under the floor. The xDrive all-wheel-drive system distributes torque with mechanical precision, combining electric torque vectoring with old-fashioned mechanical grip. The result is a 5,300-pound SUV that handles like something significantly smaller and lower.
But here is the twist no one saw coming: this BMW is built in America. The X5 line is assembled at BMW's Spartanburg, South Carolina plant - the company's largest manufacturing facility anywhere on Earth. Over 11,000 people work there, turning out SUVs for global export. Your German luxury plug-in hybrid? It has a South Carolina accent. The B58 engine may have been designed in Munich, but the vehicle surrounding it was welded, painted, and assembled in the American South.
On the road, the xDrive50e is schizoid in the best possible way. In pure electric mode, it is a 194-horsepower whisper, gliding through traffic with the serenity of a library. Floor the accelerator and the B58 inline-six wakes with a satisfying inline-six snarl, the eight-speed transmission snapping through gears like a hungry alligator. The transition is seamless. BMW has been building hybrids since the i8, and the fifth-generation eDrive system shows the depth of that experience. There is no lurch, no hesitation, no sense that two different powertrains are arguing about who is in charge.
The numbers tell part of the story. Zero to sixty in 4.6 seconds. Top speed of 130 mph. Up to 7,200 pounds of towing capacity - a figure that shames many purpose-built trucks. But numbers do not capture the duality of this machine. It is a family hauler that can embarrass sports cars at stoplights. An eco-conscious commuter that can tow a boat. A luxury SUV that happens to be American-made. The contradictions are the point.
