What is the reason for the completely flat floor in the Envision?
2 Answers
The Envision has a completely flat floor due to its chassis design, which is intended to facilitate rear passenger seating. Reasons for the completely flat floor in the Envision: The Envision features an offset exhaust pipe design, where the exhaust pipe runs parallel to the driveshaft. As a result, there is no central hump in the rear floor, making it very convenient for passengers to sit in the middle and enter or exit the vehicle. Reasons for the raised floor in some vehicles: Most joint-venture vehicles use a front-engine, rear-wheel-drive layout. Simply put, the engine is placed at the front, and the rear wheels serve as the driving wheels. To transmit power to the front wheels, a driveshaft must pass through the chassis, which is why the raised section in the rear floor corresponds to the position of the driveshaft.
I've studied the design of this car and found that the Envision's completely flat floor is primarily due to optimized chassis layout, utilizing General Motors' advanced platform technology. The exhaust pipe and drive shaft are arranged low and compact, unlike the older models with a central hump. This significantly enhances foot space for rear passengers, making it comfortable even with three people seated. I also test drove it, and getting in and out is really convenient, especially when loading luggage or pushing a stroller—the transition from the trunk to the cabin is super smooth. The engineers clearly put thought into making the car more practical. Considering the floor hump issue in traditional SUVs, which often causes tripping or installation difficulties, this new design reduces wear risks and improves durability. Overall, this change not only boosts comfort but also adds flexibility to daily use, like securely placing luggage or sports gear during long trips without worrying about shifting.
