The minimum ground clearance of the Octavia Combi is 140 millimeters. Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the car is fully loaded and stationary. It is used to indicate the vehicle's ability to pass over obstacles such as stones and tree stumps without collision. Taking the Octavia Combi 2019 Luxury Edition National VI as an example, it belongs to the compact car category with body dimensions of 4687 millimeters in length, 1814 millimeters in width, and 1509 millimeters in height, and a wheelbase of 2686 millimeters. The Octavia Combi 2019 Luxury Edition National VI is equipped with a 1.4T turbocharged engine, delivering a maximum horsepower of 150 and a maximum power output of 110 kilowatts.

As a mechanic who frequently helps people with car repairs, I have actually measured this car's ground clearance. The official data states approximately 115mm under full load, but many people don't realize this measurement is taken at a specific location, usually the lowest point beneath the front axle. I've encountered quite a few owners complaining about scraping the undercarriage, which actually has a lot to do with the tires. Switching to thicker all-terrain tires can easily add an extra centimeter of height, while lowering the car with coilover suspension will make ground clearance worse. Here's a small detail: the protruding part of the plastic guard on the rear bumper is particularly easy to overlook—it actually sits a few millimeters lower than the engine skid plate. I'd recommend installing a metal underbody guard.

Last year, I drove this car on the 318 highway. My personal experience was that it was barely sufficient when unloaded, but after loading three suitcases and luggage for four people, I had to be extra careful on unpaved roads. I specifically tested it on different road conditions: it handled ordinary dirt and gravel roads fine, but had to traverse artillery shell craters diagonally; it would definitely scrape the bottom at speeds over 40 km/h on concrete speed bumps; and curb heights couldn’t exceed 10 cm. After installing an underbody guard, it could barely handle light off-roading. Once, I accidentally entered a zone, and the gravel scraped the chassis loudly. Fortunately, the stock plastic guard was thick enough, but it was covered in scratches, so I replaced it with an aluminum-magnesium alloy one afterward.

After comparing the parameters of wagons in the same class, the Octavia's ground clearance is considered below average. The 308SW has 126mm, the Volkswagen Passat Variant has 132mm, and the Volvo V60 reaches 146mm. During development, the manufacturer prioritized handling stability by lowering the vehicle's center of gravity. The advantage is reduced body roll during high-speed cornering, with a turning radius of just 5.6 meters. The underbody is smoothly covered to minimize aerodynamic drag, but this results in a relatively low position for the middle section of the exhaust pipe. Special attention was paid to the fuel tank protective layer, which uses thick 3mm engineering plastic. However, the heat shield aluminum plate on the driveshaft is actually the component closest to the ground, making it prone to deformation from impacts.

Driving this car for three years to pick up and drop off kids, practical tests show that ground clearance depends on many details. For example, a tire pressure difference between 2.4 and 2.8 can result in a 7mm height variation, while switching to winter tires can affect diameter by over 3mm. Removing all tools from the spare tire compartment reduces weight by 4kg, indirectly increasing height by 1mm. The most problematic design is the mudguard - the rear wheel arch plastic flap has less than 10cm ground clearance, and once got torn off when hitting a snow pile. Those upgrading to larger rims should note: switching to 19-inch wheels with 35-profile low-profile tires actually reduces clearance by nearly 2cm compared to the stock 17-inch setup.
