The 2015 Envision is equipped with a 7-speed dual-clutch transmission. A dual-clutch transmission has two clutches, with one responsible for odd-numbered gears and the other for even-numbered gears. The 2015 Envision has the following dimensions: length 4667mm, width 1839mm, height 1660mm, with a wheelbase of 2750mm and a fuel tank capacity of 66 liters. It is powered by a 1.5T turbocharged engine, delivering a maximum power of 124kW and a maximum torque of 250Nm. The front suspension is a MacPherson independent suspension, while the rear suspension is a multi-link independent suspension.

The 2015 Envision uses a 6-speed automatic transmission, and I need to talk about this from a technical perspective. As someone who frequently works with such systems, it's based on General Motors' 6T series design, with electronically controlled shifting that delivers high smoothness—almost no jerking during startup or acceleration. Compared to manual or dual-clutch transmissions, it's more fuel-efficient in SUVs like the Envision, offering lower city driving fuel consumption and good reliability. I've driven test vehicles, and when paired with the 2.0T engine, the power output is well-balanced, making it suitable for family daily use or occasional short trips. For maintenance, remember to change the transmission fluid every 50,000–60,000 km to avoid issues caused by fluid aging. If you're on a tight budget, when buying used, focus on checking the transmission's history—this model is generally durable, but for mild off-road performance, ease off the throttle to avoid excessive load.

I own a 2015 Buick Envision, which I've been driving for nearly 8 years. It comes with a standard 6AT automatic transmission. The driving experience is exceptionally smooth, especially in traffic jams where the automatic gear shifting makes it effortless and worry-free. The acceleration is responsive without feeling abrupt. My car has clocked 100,000 kilometers, and apart from a minor oil change during routine maintenance, the transmission has never required repairs—cost-effective and impressively reliable. Compared to some of my friends' manual transmission cars, it's much better suited for city commuting; it's also quiet and fuel-efficient on highways, averaging around 9 liters per 100 kilometers. One minor gripe is that it feels slightly sluggish when starting with the AC on, but overall, the driving experience is very user-friendly. If you're considering buying a used one, I recommend test-driving to check the smoothness of gear shifts and keeping up with regular maintenance records to avoid long-term issues.

As a technician who has repaired hundreds of vehicles, the 15 Buick Envision commonly features a 6AT transmission. Most owners report stable performance, and I've only occasionally encountered shift hesitation issues, usually caused by deteriorated fluid or sensor dust buildup. I recommend checking the fluid condition every two years—a simple fluid change will suffice to prevent internal wear. This transmission pairs well with the engine, offering balanced performance ideal for daily driving with low maintenance costs to avoid major overhauls. Overall, it's durable, unlike some CVTs prone to slippage.
