There is no extended version of the M3. The JAC M3 is available in several variants including the Logistics Edition, Express Edition, Maker Edition, IKEA Edition, and Blind Window Edition. The JAC M3 is equipped with three types of engines: a 1.5-liter turbocharged engine, a 1.8-liter naturally aspirated engine, and a 1.6-liter naturally aspirated engine. Below are the detailed specifications of the JAC M3: 1. The 1.6-liter naturally aspirated engine in the JAC M3 delivers 120 horsepower and a maximum torque of 150 Nm. This engine reaches its maximum power at 6,000 rpm and its maximum torque between 3,500 and 4,500 rpm. It features multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. 2. The 1.8-liter naturally aspirated engine produces 133 horsepower and a maximum torque of 182 Nm. This engine achieves its maximum power at 5,600 rpm and its maximum torque between 3,600 and 4,400 rpm. It also features multi-point fuel injection technology and uses an aluminum alloy cylinder head. 3. The 1.5-liter turbocharged engine generates 147 horsepower and a maximum torque of 210 Nm. This engine reaches its maximum power at 5,600 rpm and its maximum torque between 2,000 and 4,400 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head.

I've been using the Refine M3 Extended Version for building material transportation for half a year. The actual measurements of this vehicle are 5075mm in length, 1765mm in width, and 1900mm in height. When selecting the vehicle, I specifically measured the cargo box - the extended version is 25cm longer than the standard version, allowing 2-meter PVC pipes to be loaded without tilting. The 1.9m height makes it easy to enter and exit residential underground parking, but be cautious of height restriction bars when carrying extra-tall cargo. The 1.76m width requires some skill when passing through narrow alleys in urban villages, though the electrically foldable side mirrors help. When parking, it's advisable to leave an extra half-meter space because the front end is longer than sedans, requiring position anticipation for parallel parking.

I often drive this car to take my kids to soccer games. The Jianghuai M3 Long Version, with its over-five-meter body, easily accommodates seven players plus their gear. Its 1765mm width allows three middle schoolers to sit side by side without feeling cramped, and the 1900mm height ensures even tall players don't bump their heads in the back row. The most practical feature is the 360-degree rotating second row, making it cozy for kids to play cards while waiting for matches. I remember the salesperson mentioning at pickup that it has 30cm more wheelbase than the standard version, with enough trunk space for five sports backpacks and folding chairs, plus door side grooves that can fit a crate of water bottles.

Having handled over twenty M3 models in the car rental business, I precisely remember the dimensions of the long-wheelbase version as 5075×1765×1900 mm. These specs make it a sizable contender among its MPV peers—38 cm longer than the Baojun 730 and 5 cm taller than the Fengxing Lingzhi. The most noticeable practical aspect is the 1900 mm height; clients often bump their heads when picking up the car, requiring a specific reminder to duck. During , I noticed reinforced crossbeams on the chassis compared to the standard version, likely due to the extended body's increased load capacity. On highways, extra caution is needed against crosswinds—the tall body tends to sway slightly under side winds, requiring a firmer grip on the steering wheel.

Last year, I used this car to transport samples for trade shows, and I memorized the dimensions of the Refine M3 Long Wheelbase like the back of my hand: its over-five-meter length fits foldable display stands perfectly, while the 1.76-meter width allows two standard exhibition boxes to sit side by side. The best part is the 1.9-meter height, letting me stand inside to assemble exhibits during setup. Once, I even helped a wedding company in a pinch by removing the third row to fit a three-meter-long backdrop truss. A parking lot test showed a turning radius of 5.8 meters—requiring an extra half-turn on sharp corners compared to smaller cars—but the clear rearview camera made up for it.

When converting a camper van, I took multiple measurements. The extended version of the Refine M3, with its 5075mm length, is sufficient for a fixed bed. The 1765mm width perfectly accommodates an 80cm-wide cabinet, leaving a 40cm aisle for passage. The 1900mm height is crucial for standing upright without hitting your head, and even after installing solar panels on the roof, there's still a 1.7m clearance. The modification shop owner mentioned that these dimensions are particularly suitable: the rear axle is reinforced compared to the standard version, preventing the rear from sagging when fully loaded. However, pay attention to the rear door opening height; the outdoor shower box needs to be tilted to fit, and the 60cm-high threshold makes lifting heavy items a bit strenuous on the back.
