To find the horsepower of a 2010 Land Rover Range Rover Sport, I recommend:
* Checking the vehicle's owner's manual: This should list the engine specifications.
* Visiting the Land Rover website: You can often find detailed information about specific models on the manufacturer's website.
* Consulting a reliable automotive resource: Websites like Edmunds, Kelley Blue Book, or Car and Driver usually have comprehensive vehicle information.
Please note that the horsepower can vary depending on the engine option chosen for the 2010 Range Rover Sport.
