Why Not Buy a Car with 4AT?
2 Answers
On a crankshaft, the more cylinders connected, the smoother the operation. Each additional cylinder means an extra power output. This is why high-end cars with large displacements are equipped with 6-cylinder or 8-cylinder engines. In fact, the 6-cylinder engine is considered the best due to its superior second-order dynamic balance. However, to balance dynamic performance and cost considerations, most automakers opt for 4-cylinder engines. Below are specific details about 4AT: 1. Introduction: A 4AT transmission refers to a 4-speed automatic transmission, which is the most basic type in automatic cars. The four gears include Park (P), Reverse (R), Drive (D), and Neutral (N). 2. Features: The AT transmission does not require a clutch for gear shifting, making it relatively simple to operate.
As a car owner who frequently changes vehicles, I really don't recommend buying cars with 4-speed automatic transmissions. I've driven a friend's older car equipped with this transmission, and the driving experience was particularly poor. The gear shifts were noticeably jerky, especially in stop-and-go city traffic—every time I accelerated at low speeds, the car would shake uncomfortably. Fuel consumption is also significantly higher, burning about 20% more fuel compared to modern 6-speed automatic transmissions. With current high gas prices, this could cost thousands more per year. On highways, the engine runs at higher RPMs, creating excessive noise that makes long trips unbearable for the ears. Maintenance is another issue, as parts are outdated, often out of stock, and repairs are expensive and time-consuming. Newer models use dual-clutch or CVT transmissions, which are smoother, more fuel-efficient, and safer. I'd strongly advise avoiding 4AT and opting for newer technologies for a much more hassle-free experience.
