Honda engineers took a bold step in the 2016 Civic to give it a nice tight steering lock to lock turn ratio. The Civic has a variable ratio EPS, and a sporty 2.2 turns lock-to-lock steering. The previous 9th Gen Civic had a more typical 3.1 turns lock to lock ratio, and most family sedans are around 3+ turns lock to lock. For a benchmark, the 997 Porsche GT3 RS has a 2.6 turn lock to lock steering, and the E92 M3 has a 2.4 turn lock to lock steering. Tighter lock to lock ratio make the car more responsive and quick while a longer lock to lock is a more comfortable lazy drive during long distance high speed cruises.
"Dual-Pinion, Variable Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)
Another Civic first, the Electric Power Steering (EPS) incorporates dual pinion gears and a variable gear ratio for improved steering feel, performance and comfort that surpasses the class.
The dual pinion steering provides substantially improved feel compared to the previous-generation Civic. Compared to a traditional single-pinion steering system, the dual pinion EPS utilizes the physical steering input from the driver as well as from a supplemental electric motor. A non-contact torque sensor measures the driver's steering effort and an ECU determines how much electric motor assist to add, with the result being a seamless, natural feeling steering in all situations.
The steering ratio is variable over a 17-percent range with a final full off-center rotation ratio of 10.93:1. This provides a quick 2.2 turns lock-to-lock compared to 3.1 turns lock-to-lock for the previous Civic, significantly reducing hand movement and the steering effort required when parking or maneuvering. Also contributing to the enhanced steering performance and feel of the 2016 Civic Coupe, the steering mount stiffness is higher, and the 30mm steering column diameter (up from 22mm on the previous generation Civic) also provides greater stiffness."

Read about the rack being variable as well though I can't say that I've noticed it vary-ing. Hmm, maybe thats a good thing. Lol."Dual-Pinion, Variable Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)
