Mazda CX-5s are compact crossover SUVs that seat five passengers. They're available in three trim levels: Sport, Touring and Grand Touring. The Sport comes standard with a 2.0-liter four-cylinder engine (155 horsepower, 150 pound-feet of torque) that's paired with a six-speed manual transmission or an optional six-speed automatic. A 2.5-liter four-cylinder engine (184 hp, 185 lb-ft) is available on upper trims and only with the automatic transmission. Front-wheel drive is standard and all-wheel drive is optional on any model.
In terms of cargo space, the Mazda CX-5 has 30.9 cubic feet behind the rear seats and 59.6 cubes with them folded down. With the front passenger seat also folded down, there's a maximum of 64.8 cubic feet to work with. As for kayaks, they vary quite a bit in size, but let's assume you've got a 10 footer (a popular length).
With the hatchback open and both backseats down, you should be able to get your kayak inside the Mazda CX-5 without too much trouble – just be careful not to scratch up the paint! You may need to remove the front passenger seat headrest in order to get it all the way in, but other than that it should fit without issue provided you can tilt it up vertically and slide it into place without hitting anything else inside the vehicle.
