Where are the three major components of the Haima 8s from?

The chassis and engine of the Haima 8s are basically independently developed, and the transmission is a product sourced from Aisin. Here is some extended information: 1. The functions of the transmission are: (1) Changing the transmission ratio to meet the traction needs under different driving conditions; (2) Enabling reverse driving; (3) Interrupting the power transmission to the drive wheels when the engine starts, idles, the car shifts gears, or needs to stop for power output. 2. Vehicle introduction: Taking the 2020 manual comfort Haima 8s as an example, its body structure is a five-door, five-seat SUV. The body dimensions are: length 4565mm, width 1850mm, height 1682mm, wheelbase 2700mm, front and rear track 1590mm, fuel tank capacity 58l, trunk capacity 552l, and curb weight 1545kg.

I've previously researched this car. The 1.6T turbocharged engine in the Haima 8S is independently developed by Haima, with the model code HMA GA16-YF, delivering a maximum power of 195 horsepower and a peak torque of 293 N·m. It's paired with a 6-speed automatic manual transmission provided by Dongan Power, offering smooth performance that's quite comfortable for city driving. The chassis features a front MacPherson and rear multi-link independent suspension setup, tuned overall for family comfort with good vibration damping over speed bumps. These core components are essentially mature solutions within the domestic supply chain system, making later maintenance costs relatively friendly.

The Haima 8S is powered by their in-house developed third-generation 1.6TGDI turbocharged engine, which reportedly achieves a thermal efficiency of 37%, higher than many joint-venture models. The transmission is a 6AT produced by Harbin Dongan Automotive Engine, and when I drove my friend's car, I found the shift logic quite intelligent—it could drop two gears in succession with a hard press on the accelerator. The chassis structure is nothing special, with MacPherson struts at the front and a multi-link setup at the rear, though the rear suspension's lower control arm uses stamped steel plates, which doesn't do well in terms of lightweighting, resulting in noticeable tire noise at high speeds. Still, for an SUV priced just over 100,000 yuan, this combination is quite solid.

The origins of the three major components are quite transparent: the engine is a self-produced 1.6T from Haima's Zhengzhou base, with a low-inertia turbo delivering maximum torque at just 1,750 rpm; the transmission is supplied by Dongan Power, the same 6AT used in the early Chang'an CS75; the chassis design draws inspiration from the Hyundai ix35, featuring an L-arm front suspension to enhance lateral rigidity and a rear four-link setup with an anti-roll bar. However, the steering system utilizes EPS electronic power assistance from Hubei Henglong, offering a commendable steering feel—light at low speeds and firm at high speeds.

Upon a detailed breakdown of the technical specifications: The engine features direct fuel injection and DVVT technology, with an aluminum cylinder block reducing weight. The transmission is from the Dongan DATIC6 series, capable of handling 300 N·m of torque, which perfectly matches the engine. The chassis highlights include dual-channel shock absorber bushings in the front suspension, absorbing 15% more vibrations on bumpy roads, but the rear suspension springs are relatively soft, resulting in average cornering support. The subframe is a full-frame structure, offering higher safety coefficients compared to the yuanbao beam.
