What is the actual measured ground clearance of the CT4?
4 Answers
The ground clearance of the CT4 is 150mm. Below is a relevant introduction to the CT4: 1. In terms of interior, the CT4 adopts a new center console layout, with features such as an 8-inch floating central touchscreen and various shortcut operation buttons slightly tilted towards the driver for easier operation. The Bose sound system, combined with virtual surround sound technology, creates captivating audio effects inside the car. 2. In terms of powertrain, it comes standard with a 2.0T variable-cylinder turbocharged engine paired with an 8-speed automatic transmission. The variable valve management technology enables three operating modes: four-cylinder high-performance mode, four-cylinder economy mode, and two-cylinder ultra-economy mode, achieving a fuel consumption as low as 6.7 liters per 100 kilometers. 3. The Cadillac CT4 is built on a new-generation lightweight rear-wheel-drive platform, with dimensions of 4712mm in length, 1825mm in width, and 1421mm in height.
I've been driving my CT4 for almost two years and specifically measured the ground clearance with a tape measure. When measured unloaded, the front bumper position is about 14.5 cm, and the bottom of the fuel tank is approximately 15.3 cm. This height is completely sufficient for city driving, but last time I encountered a gravel road in the suburbs and still scraped the undercarriage. Special attention should be paid to the fact that the rear suspension of this car is lower than the front, making the rear bumper particularly prone to scraping when going up steep slopes. Once, when I loaded three cases of mineral water in the trunk, I clearly felt the ground clearance reduced by about one centimeter. The mechanic at the tuning shop said the factory-set height is more sport-oriented, and to improve off-road capability, the suspension would need to be replaced, but it would affect the handling feel.
During the test drive, I specifically paid attention to the ground clearance of the CT4. The sales brochure states an unladen height of 148mm. Actually measuring it in the 4S store parking lot showed about 14.6cm clearance near the front wheels, slightly lower than the official figure. This height is roughly two fingers lower than an Audi A3, requiring extra caution with speed bumps and mounds on mountain roads. A friend who runs an auto repair shop mentioned they've serviced many CT4 underbody panels, mostly scraped from hitting deep potholes. The issue becomes more pronounced when loaded - with four adults onboard, the chassis sinks nearly 2cm lower. For frequent off-road driving, installing an alloy underbody shield to protect the oil pan is highly recommended.
I scraped the chassis in the first week after picking up the new car, and immediately measured the clearance in distress. The specific data is: 14.3cm under the front axle and 15.1cm at the rear differential. This ground clearance is 7-8cm less than common SUVs, but slightly better than sports cars. Extra caution is needed when entering underground garages—some shopping mall ramps are poorly designed, and I've witnessed a CT4 getting stuck at the crest. After installing lowering springs, the clearance dropped below 13cm, improving cornering stability but worsening passability. In stock condition, clearing 15cm obstacles is safest; any potholes exceeding 18cm must be avoided.
