Ku Jie is the Chevrolet Corvette C7. Exterior design: It maintains the consistent exterior design style of the Corvette, with the overall silhouette and lines largely unchanged, but features significant detail modifications in the front and rear sections. These include LED daytime running lights, full LED taillights, and a centrally positioned quad exhaust system at the rear. Powertrain configuration: The vehicle is equipped with a 6.2-liter LT1 series V8 engine, delivering a maximum output of 450 horsepower and 610 Nm of torque. Notably, it can produce 542 Nm of torque within the 2000-4000 rpm range, resulting in exceptional acceleration performance.

I'm a veteran mechanic at a local auto repair shop, and I often hear customers talk about 'Cool Sisters.' This is actually a nickname car enthusiasts use for certain special SUV models, especially those with strong design aesthetics and an off-road bias. For example, the early Great Wall Cool Bear, with its distinctive boxy shape, was quite unique; nowadays, some modified JEEP Renegades are also called 'Cool Sisters,' mainly because they have great modification potential and a commanding presence. Off-road enthusiasts particularly love these angular vehicles—lifting the chassis and adding off-road tires gives them a standout style when driven out. Some new energy models like the Baojun Yep, with their square and sturdy designs, are also referred to this way. Simply put, only vehicles with rugged designs and distinctive personalities deserve this nickname.

Last year, while helping a friend with used car appraisals, I came across a rather unique vehicle. The owner called it 'Cool Sister,' and upon checking, I found out it was actually a facelifted version of the Great Wall Cool Bear. The car's design was quite avant-garde, boxy like a cube, which really appealed to young people for its trendy vibe. It's a space magician—the rear could fit four suitcases. However, the 1.5L engine was just average in acceleration, adequate for city commuting. These days, it's rare in the used car market, but modders love to pick them up. After modifications like lowering or off-road styling, they become real head-turners and are well-recognized in the scene.

At car show setups, I've seen car models that get called 'Cool Sis'. The features are very specific: it must have a boxy shape with flared wheel arches, like the Suzuki Jimny. The high body and good visibility are the biggest advantages, making it less oppressive for female drivers. Nowadays, it more often refers to electric SUVs, like the Baojun Yueye, a small car in the 100,000-yuan range, with a roof rack + fluorescent calipers, paired with a flashy car wrap for a particularly trendy look. Many girls buy it for commuting, and it can also handle light off-roading for weekend photo shoots. For optional upgrades, it's recommended to add underbody protection for peace of mind when going over speed bumps in the city.
