What Causes Loud Engine Noise and Weak Acceleration?

Engine noise and weak acceleration can be caused by: 1. Carbon buildup: Excessive carbon deposits inside the engine reduce ignition energy and intake efficiency, leading to decreased engine power, resulting in sluggish acceleration and muffled sounds; 2. Fuel system issues: Using incompatible fuel grades (e.g., using 90 octane instead of 93 octane) reduces vehicle power output and performance; 3. Air intake problems: As air is one of the engine's power sources, a clogged air filter from prolonged use without cleaning can cause insufficient airflow, leading to an overly rich air-fuel mixture and reduced engine power; 4. Engine overheating: Insufficient engine oil, low coolant levels, or faulty cooling system components can increase engine load and cause poor heat dissipation.

What is a Torque Vectoring System?

A torque vectoring system refers to a system that can distribute power between the left and right wheels of a vehicle. When navigating a curve, it allocates more power to the outer wheel, enhancing stability during cornering. Here are the details: 1. When the vehicle turns right: The left rear wheel transmits more power to the road, so the torque vectoring system allocates more driving force to the left rear wheel. 2. When the vehicle turns left: The torque vectoring system delivers more driving force to the right rear wheel, causing it to transmit more power to the road in this scenario. 3. When the vehicle travels straight: The torque vectoring system distributes equal power to both rear wheels, ensuring optimal traction.
