2.4-liter i-VTEC Engine
Standard Feature
2.4-liter i-VTEC Engine

The same powerplant found in the TLX sport sedan is now in every ILX model. The aluminum block, direct-injected 2.4-liter inline-four delivers 201 high-revving horsepower, 181 lb. ft. of torque (both SAE net) and best-in-class thrills per mile. Unlike turbocharged engines, throttle response is immediately impactful while the engine’s light weight makes handling nimble and fuel economy notable.

  • Intelligent Variable Timing and lift Control (i-VTEC®) increases horsepower by opening intake valves longer and deeper at approximately 4500 rpm and above. This high rpm airflow is further enhanced by Variable Timing Control that incrementally advances the opening of intake valves as rpm rises.
  • Direct Gas Injection sends fuel directly into each cylinder through a multi-hole injector for a more precise, effective air/fuel mixture. In addition to added performance, this process significantly lessens fuel consumption at engine start.
  • Fuel directly injected into a cylinder also has a cooling effect allowing power-increasing higher compression with no engine knocking.
  • The engine’s rigid aluminum block reduces weight for improved handling.
  • Reduced friction equals increased fuel efficiency. Here are a few ways it’s done on the ILX:
    • Offset cylinders
    • Low-tension piston rings
    • Double-arm chain system
    • Exclusive belt layout for EPS
  • The Drive-by-Wire™ system supplies exceptional throttle response and driver feel when navigating challenging conditions.
  • With an EPA Fuel Economy Rating27 of 25/ 36 / 29 mpg (city/highway/combined), the ILX is efficiently fun.
8-Speed DCT (Dual-Clutch Transmission)
Standard Feature
8-Speed DCT (Dual-Clutch Transmission)

Along with the new engine, all 2016 ILX models are equipped with the sophisticated 8-speed DCT transmission. Originally developed for racing, the dual-clutch design shifts faster, smoother and with greater efficiency than conventional automatic transmissions. Designed in-house, drivers will find it a perfect fit for the high-revving inline-four engine.

  • Unlike a conventional automatic, the new transmission changes gears though clutches (much more like a manual transmission) rather than simply a torque converter.
  • The transmission has one clutch for odd-numbered gears (1, 3, 5, 7) and a second for even ones (2, 4, 6, 8). While one clutch is engaged with the current gear, sensors predict whether the next gear change will be an upshift or a downshift. The second clutch then prepares the next gear ratio for engagement so when the shift occurs it’s instant with a negligible loss of engine torque.
  • Eight gear ratios keep the 2.4-liter engine running at or near peak efficiency at nearly all speeds.
  • Because dual-clutch transmissions have been known to shift roughly (particularly from a stop), Acura took the unprecedented step of maintaining a torque converter for a smoother launch.
  • The true performance potential of this new 8-Speed DCT is brought out by paddle shifters that enable lightning fast shifts that take only milliseconds versus a typical driver’s manual shift of about a half second. Such quick-response shifting makes lively acceleration out of a turn or engine braking down a mountain road particularly satisfying.
Suspension Systems
Standard Feature
Suspension Systems

The ILX uses a combination of MacPherson struts for the front suspension and a multi-link arrangement in the rear. Using a strut-style front suspension makes more room available for crash reinforcement. The multi-link rear suspension helps maximize second-row seating and cargo space—all while providing outstanding handling and ride quality.

  • The MacPherson struts front suspension has specially tuned bushings and performance-calibrated geometry, providing optimal wheel alignment while turning for smooth, solid handling.
  • The multi-link rear suspension includes stamped-steel upper A-arms, cast aluminum knuckles, double lower lateral links, steel-toe control links, coil-over dampers and a large stabilizer bar.
  • Compared to previous ILX models the front suspension bushings have been revised and the rear stabilizer bar has been thickened to tighten road feel and reduce body roll.
  • Amplitude Reactive Dampers feature two pistons per damper (a.k.a. shock absorber) rather than one. The first piston reacts to help absorb minor road vibration, while the second one is stiffer, reigning in a larger suspension motion for improved stability.
Steering System
Standard Feature
Steering System

The ILX steering system is a good example of the subtle ways a luxury car differentiates itself from more conventional vehicles.

  • The ILX’s already rigid mounting for the steering assembly is strengthened even further for 2016 increasing linear feel for greater steering precision while reducing low and high-speed vibration.
  • The rack-and-pinion is tuned to provide a smooth, linear transition between generous power assist at low speeds and a firmer feel at higher speeds.
  • Electronic, rather than hydraulic power, assist does not draw mechanical power from the engine, increasing its efficiency.
Performance Braking
Standard Feature
Performance Braking

The four-wheel disc brakes are designed with several subtle enhancements to improve their performance over conventional cars of the same size.

  • Strengthened calipers improve effectiveness while enlarged splash shields help increase fade resistance.
  • The pedal shape is designed to direct force on the pedal center to increase response.
  • All models have 12.3-inch ventilated discs in the front and 11.1-inch solid discs in the rear.
  • Electronic Brake Distribution uses the anti-lock brake sensors to determine the proportion of brake force to be channeled to each wheel for increased performance and stability.
Rigid Body Structure
Standard Feature
Rigid Body Structure

Though not apparent to the naked eye, body structure is one of the best examples of what distinguishes the ILX from conventional cars of its size.

  • Significant structural enhancements can be found at the frames around each door opening and across the rear of the trunk-lid opening.
  • Other enhancements include reinforced joints and replacing multiple components with single components to smooth stress flow.
  • Lateral flex has been reduced through strengthened joints around the front suspension sub-frame mounting.
  • Close to 59% of the vehicle’s weight is made up of high-tensile steel, which is lighter and stiffer than conventional structural steel.
  • Aluminum was used for the hood to reduce the center of gravity and at the bumper beams to reduce polar inertia, both of which improve handling.
Smooth & Quiet Ride
Standard Feature
Smooth & Quiet Ride

A variety of measures were taken to ensure the ILX delivers the refined ride of a luxury road car.

  • Significant wind tunnel testing reduced areas of wind turbulence such as the windshield base, the trailing edge of the trunk and across the entire floor-pan.
  • The front body corners were shaped to reduce tire air turbulence.
  • A floating front sub-frame structure with heavily reinforced mounting points reduces road noise.
  • Four resonators in the intake manifold reduce engine induction noise during acceleration.
  • The alloy wheels contain resonators to absorb the sound of air bouncing between tire and wheels.
  • Standard Active Noise Cancelation listens to ambient engine and wind noise and produces an equal yet reverse sound through the audio system causing the two sounds to cancel each other out.
