For 2021, the X5's xDrive50i model has been replaced by the plug-in hybrid xDrive45e. The new plug-in hybrid powertrain consists of a turbocharged 3.0-liter inline-six and an electric motor for a total output of 389 horsepower. A 24.0-kWh battery pack is said to provide up to 30 miles of electric-only driving range. The regular 40i models also receive some light electrification in the form of a 48-volt hybrid system.
Pros Wide range of available engines, high-quality cabin materials, intuitive infotainment interface.
Cons Somewhat vague steering feel, tight third-row passenger space, V-8 performance costs a lot extra.

Pros Strong performance from available engines Luxurious, comfortable cabin lives up to its price tag Spacious cabin and cargo area
Cons Small mirrors and wide roof pillars create blind spots Limited interior storage Wide doorsills inhibit entry and exit
Like the regular Q5, the high-performance SQ5 receives a host of exterior updates, including an all-new Sportback variant, for 2021 to freshen its look. New exterior lighting elements, a tweaked grille and bumpers, and new wheel designs differentiate it from last year's model. The top-spec Prestige gets OLED taillights as standard, and two new colors join the palette: Ultra Blue and District Green.
Pros Handsomely-equipped cabin, comfortable ride, decent fuel economy for a performance SUV.
Cons Not overly spacious, turbo V-6 doesn't match rivals' horsepower, handling not as sharp as it could be.
Sportier Sportback does well to not compromise on practicality, but you’ll pay a premium for odd looks.
Pros Impressively practical despite the roof, interior is still top of the class
Cons It will give you an existential crisis. What is it all for?
All-new model for 2021.Has a sleeker style than the regular SQ5.Comes standard with an adaptive sport suspension.Part of the first Q5 Sportback generation introduced 2021.
Pros Impressively comfortable ride for a sport-tuned SUV Luxurious but restrained interior design Nimble handling
