They can be distinguished by appearance and rear badges. Below is the relevant information: Versions: The Q50L is the domestically produced long-wheelbase version of Infiniti. The Q50 is the imported version of Infiniti. Dimensions: The Q50L measures 4840mm in length, 1823mm in width, and 1456mm in height, with a wheelbase of 2898mm. The sport version has a length of 4852mm. The imported Q50 measures 4790mm in length, 1823mm in width, and 1450mm in height, with a wheelbase of 2850mm. The sport version has a length of 4802mm. Badges: The domestically produced Q50L has a "Dongfeng Infiniti" badge on the rear. The imported Q50 comes with two powertrain configurations: 2.0T and 3.7L. The domestically produced Q50L only has a 2.0T powertrain configuration.

I've driven the Infiniti Q50 and Q50L several times, and the most noticeable difference between them is their size and space. The Q50L is the extended version of the Q50, with an approximately 48mm longer wheelbase, which translates to more spacious legroom and shoulder room in the rear seats. During my test drives, I noticed that the Q50L's back seats are particularly comfortable, especially when traveling with family—kids and elderly passengers can stretch their legs without any issues. On the other hand, the Q50 offers better handling when taking corners, though the rear seats feel a bit tighter. Externally, the Q50L's doors and rear lines appear slightly fuller, though it's hard to notice at a glance. The extended wheelbase also increases the overall length of the car, but the trunk capacity remains largely unchanged, with improved internal lateral space, making daily shopping or loading luggage much easier. The Q50L provides better stability at high speeds, though the turning radius is slightly larger, but parking in crowded urban areas isn't too difficult. In terms of maintenance, both models share the same engine and most parts, with minimal cost differences, so I'd recommend the Q50L for family use as it's more practical.

From my daily driving experience, there's quite a noticeable difference in driving feel between the Infiniti Q50 and Q50L. The standard Q50 has a shorter wheelbase, making it exceptionally agile during turns with a sporty handling character that's particularly enjoyable during quick lane changes or mountain road driving. The Q50L, with its extended wheelbase, has adjusted overall weight distribution, offering greater stability during high-speed cruising with reduced bumpiness, though it responds slightly slower in sharp turns with a larger turning radius, requiring more attention during parking maneuvers. Both share the same 2.0T engine with similar acceleration performance, but the extended version shows marked improvement in ride comfort with softer rear suspension damping. As someone who frequently takes long trips, I find the Q50L's rear seats moderately firm yet fatigue-resistant for extended sitting, making it ideal for carrying passengers or long-distance travel. The interior layouts are essentially identical, though the Q50L offers more spaciousness without feeling cramped, delivering quieter and more relaxed driving. Price-wise, the Q50L commands a slight premium in the Chinese market, but the enhanced rear comfort justifies the few thousand yuan difference. Tire replacement and maintenance costs remain comparable without additional burdens.

I understand the Infiniti model market. The Q50L is primarily targeted at Chinese users with an extended wheelbase, differentiating it from the standard Q50. The core difference lies in the rear seating space: the Q50L has a longer wheelbase, offering more legroom, which suits buyers who prefer a luxurious rear seating experience; the original Q50 is more compact and offers more agile driving. In terms of appearance, the Q50L features slightly elongated side door lines and minor adjustments to the rear door design, resulting in more harmonious proportions. Price-wise, the Q50L has a slightly higher starting price but comes with enhanced configurations like softer seat materials for a more comfortable ride. While there is a slight compromise in handling, comfort is significantly improved, especially with superior shock absorption performance on uneven Chinese roads. Other aspects such as fuel consumption and maintenance are largely the same, so the choice depends on personal preference.
