has revealed full details and gallery of photos of its all-new X5 SUV, or SAV (Sport Activity Vehicle) in BMW-speak. Compared to its immediate predecessor, the new X5 isn’t a dramatic departure but there are a few notable changes. For starters, buyers can now opt for the sDrive35i trim, the first time a rear-wheel-drive version of the vehicle has been offered. All-wheel drive, of course, remains optional. The base engine is the automaker’s familiar 3.0-liter twin turbo inline-six that’s good for 300 horsepower and 300 lb-ft of torque and mated to an eight-speed automatic transmission.
