The Lada Priora car is equipped with a 16-valve injection engine mod. located transversely in the engine compartment. VAZ-21126-00 with a working volume of 1.6 liters. The engine is equipped with a distributed fuel injection system and a catalytic converter of exhaust gases, structurally made in a single block with an exhaust manifold (cat collector).
The body is load-bearing, all-metal, welded construction, with hinged doors, front fenders, hood and trunk lid.
The driver's seat of the Lada Priora is equipped with an airbag as standard, and an optional front passenger airbag, as well as front seat belts with pretensioners and load limiters, which significantly reduces the likelihood and severity of head and chest injuries in a traffic accident.
Note: The airbag will only deploy if the front of the vehicle is hit with a significant force. In minor frontal impacts, rollovers, rear-end impacts or side impacts, seat belts are the primary means of protection.
The transmission is made according to the front-wheel drive scheme with drive wheels of different lengths.
The front suspension is independent, spring, with anti-roll bar, with hydraulic shock absorber struts. The rear suspension is semi-independent, lever-spring, with hydraulic shock absorbers.
The front wheel brakes are disc brakes with a floating caliper, and the rear wheel brakes are drum brakes.
In the variant version, Lada Priora cars are equipped with an anti-lock braking system, which prevents the wheels from locking during braking and maintains controllability and directional stability.
The steering is trauma-safe, with a rack-and-pinion steering mechanism, with an electromechanical booster that changes the transmitted torque depending on the vehicle speed.
Lada Priora cars are equipped with a remote control system for locking or unlocking door locks (in a variant version and with a trunk lid lock) with simultaneous switching on or off of the vehicle's security mode. In addition, there is a provision for remote activation of the alarm system in case of violation of the vehicle's security zones and blocking of all doors by pressing a button from inside the vehicle.
This system also includes an electronic engine immobilizer system (immobilizer), providing additional protection against unauthorized engine starting.
