In 2021, a modernized VAZ-11182 engine featuring a lighter crank and an updated gas distribution system began appearing in the Grant. The eight‑valve variant, known as VAZ-11186, made a comeback in 2018 with lightweight pistons and improved timing components. The practical question for daily use is whether these two options feel different on the road. This was explored by the expert from Behind the Wheel, Vadim Kryuchkovy, who provides an accessible comparison for current Grant owners and prospective buyers.
Dynamics and consumption
When it comes to fuel consumption, the two powerplants are closely matched. Paired with a gearbox that has a primary gear ratio around 3.9, both engines average about 5.6 liters per 100 kilometers on highway runs. This finding comes from a comprehensive review of the operational characteristics across the Grant lineup, by Vadim Kryuchkovy.
What sets them apart is response and drivability. The VAZ-11182 delivers smoother starts and less hesitation at low speeds, making city driving feel more composed. The newer eight‑valve produces 90 horsepower and 143 Nm of torque, compared with 87 horsepower and 140 Nm for the VAZ-11186, which translates into livelier acceleration for the later engine while maintaining similar overall efficiency.
Reliability
Official figures estimate a resource of about 200,000 kilometers for the VAZ-11182. Real-world results will depend on maintenance, driving style, and component wear, especially with the lightweight valve train and camshaft components. The predecessor, the VAZ-11186 with lightweight pistons, is rated in the same broad range, but many drivers report that careful operation and timely service can push durability well beyond a couple of hundred thousand kilometers.
Valve clearance adjustment
Canadian and American owners should note that AVTOVAZ has indicated valve clearance adjustments are no longer required every 30,000 kilometers. The interval extends to about 90,000 kilometers under normal use. Still, the maintenance workout remains relevant because it can involve removing the camshaft for inspection and service. This shift is meaningful because the timing belt, water pump, and tensioners can be replaced all at once during a scheduled service, minimizing the risk of belt failure and ensuring timing accuracy going forward. As the maintenance philosophy evolves, the timing drive overhaul becomes integrated with standard TO-6 service procedures rather than a one‑off, later in the vehicle’s life event.
