    [​IMG] Possibly the best C-segment ever offered is loaded with comfort, ride and handling inducing technology.

    Wayne Gerdes – CleanMPG – Oct. 18, 2015

    2016 Honda Civic static reveal in Los Angeles last month.

    There is nothing like a new C-segment (compact) to move emotions. Despite the low fuel cost driven CUV segment outselling the midsize and compact offerings, no other group provides the most modern equipment and appointments in an exciting looking and affordable package.

    When someone thinks of a solid C-segment car available in the U.S., the Corolla, Civic, Elantra and Mazda3 immediately come to mind. The all-new 10th gen Civic may be the car that Honda has planned to turn it from another class leader to "the class leader."

    In the case of the all-new 10th gen 2016 Civic, on paper it looks to be the segment leader bypassing the Corolla with intense engineering on the R&H front, the Elantra with an all-new aggressive design from any angle including the top, and even moves the bar on some of the C-segment premium brands offerings with the latest infotainment and low NVH. Whoops, I have not driven it yet so I had better hold off on that anointing.

    And in case you have not been following, the 2016 Civic's 97.8/95.0 cu. ft. of interior passenger volume for the LX and sunroof lineup respectively plus the 15.1 cu. ft. of trunk cargo volume move the entire lineup into the Midsize category for 2015. No other competitor offers this amount of passenger and cargo room in the highly competitive compact class.

    2016 Honda Civic Sedan - Chassis Overview

    The 2016 Civic Sedan utilizes the most sophisticated chassis design in model history, delivering quicker and more accurate steering, more responsive handling, and exceptional ride quality that exceeds the mainstream, compact-car class to challenge even luxury C-segment products.

    Key suspension upgrades include a new multi-link rear suspension and rigid rear subframe; fluid-filled suspension bushings that greatly enhance ride quality while providing robust isolation from road vibration; stabilizer bars with bonded bushing mounts for improved body control; dual-pinion, variable ratio Electric Power Steering (EPS) that enhances steering feel, performance and comfort; and a Straight Driving Assist feature that reduces steering effort when driving on a sloped or crowned road. Additional new Civic chassis features include Agile Handling Assist and an Electric Parking Brake (EPB) with Automatic Brake Hold.

    Front and Rear Suspension

    The 2016 Civic suspension system places the Civic at what they are calling best-in-class thanks to European luxury-class competitor benchmarking. The system uses a combination of struts up front and an all-new multi-link with new rigid subframe out back. With the front struts, more room is available for crash reinforcement, and the multi-link rear end improves second-row seating and cargo space.

    The 2016 Civic a 0.6 in lower center of gravity, helping to improve both handling agility and rollover resistance.

    2016 Honda Civic MacPherson Strut Front Suspension

    [​IMG]

    The MacPherson strut front suspension is reengineered with performance-calibrated geometry. The lower suspension arms are connected to the subframe and to the body via fluid-filled bushings, which provide improved handling and minimal NVH. All front suspension arms and the front hub carriers are steel, and all Civic Sedan trims use a tubular front stabilizer bar. The stabilizer bar is bonded to their mounting bushings and use low-friction connecting links for smoother operation.

    2016 Honda Civic Multi-Link Rear Suspension

    The multi-link rear end includes stamped-steel arms, cast aluminum hub carriers and a stabilizer bar. Mounted on a rigid subframe, the new rear suspension provides better handling and minimal body roll. The trailing arms are located on the unibody in fluid-filled bushings. All Civic Sedan trims use a solid rear stabilizer bar. Like the front stabilizer, the rear is bonded to its mounting bushings and use low-friction connecting links.

    [​IMG]

    2016 Honda Civic Hydraulic Suspension Bushings

    The 2016 Civic suspension uses fluid-filled bushings to provide superior ride isolation and minimizes chassis vibration. All Civics utilize front fluid-filled bushings and the EX-T and above trims additionally use rear fluid-filled bushings. These bushings are specifically tuned to provide minimum vibration transfer to the occupants, raising the new Civic to the best-in-class NVH reduction.

    In front, the lower control arms pivot in the fluid-filled bushing, which is designed to absorb road harshness and vibration while still retaining the exacting precision required for sharp, nimble handling. For the front suspension only, a specially ventilated under-cover allows airflow to cool the bushings, ensuring more consistent performance in all ambient temperature conditions, as well as enhanced long-term durability.

    An additional duct, located near the middle of the aluminum front under-panel, cools the engine's torque rod bushing, likewise reducing operating temperatures and ensuring longer performance.

    2016 Honda Civic Dual Pinion Variable Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)

    The Electric Power Steering (EPS) incorporates dual pinion gears and a variable gear ratio for improved steering performance.

    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 an 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 the steering effort when parking or maneuvering. Also contributing to the enhanced steering performance and feel of the 2016 Civic Sedan, the steering mount stiffness is higher, and the 1.2 inch steering column diameter (up from .87 inches on the previous generation Civic) also provides greater stiffness.

    2016 Honda Civic Straight Driving Assist

    Straight Driving Assist reduces the steering effort required when driving on a sloped or crowned road. When the Straight Driving Assist system detects that steering effort is being applied to keep the car driving along a slope, the Electric Power Steering system applies motor assist. This reduces the muscle effort required to maintain the desired direction on the sloped road to the same level as is required on a flat road.

    2016 Honda Civic 4-Wheel Disc Brakes with ABS, EBD and Brake Assist

    All trims are equipped with 4-wheel discs with 4-channel ABS, Electronic Brake Distribution (EBD) and Brake Assist standard. The system provides high-performance stopping in emergency situations. Compared to the previous-generation, the 2016 Civic's brakes require less pedal travel, provide a firmer pedal feel under normal conditions, and deliver greater efficiency.

    The 4-channel Anti-lock Braking System (ABS) independently modulates braking power at each wheel to help the driver retain steering control during heavy braking. The Brake Assist system recognizes emergency braking situations and almost instantly applies full braking force when appropriate to help shorten braking distance. (See the Safety and Driver Assistance section for more information.)

    All 2016 Civic trims are equipped with 11.1-inch diameter ventilated front brake rotors (0.9-inch rotor thickness) clamped by single-piston brake calipers. The rear disc brakes incorporate 10.2-inch diameter solid rotors (0.4-inch rotor thickness) paired with single-piston brake calipers. The low-friction design of the brake calipers reduces energy losses when the brakes are not in use, directly improving fuel efficiency.

    In another first for Civic, a 5-percent-larger master cylinder piston diameter (0.874 in vs. 0.811 in on the previous Civic) contributes to the short, firm pedal stroke and excellent feel, while also maintaining the power of the braking system.

    2016 Honda Civic Vehicle Stability Assist (VSA) with Traction Control

    Vehicle Stability Assist (VSA) works in conjunction with the Drive-by-Wire throttle and its 4-channel ABS systems to enhance control while the vehicle is accelerating, braking, cornering or when the driver makes a sudden maneuver.

    VSA provides a limited-slip differential effect for the driving wheels by applying braking force to a slipping wheel and redirecting driving force to the wheel with more traction. While the driver can reduce the traction control effectiveness allowing more wheel slip during stuck condition by pressing the VSA button, ABS remains fully operational at all times.

    2016 Honda Civic Agile Handling Assist

    Standard on all trims, Agile Handling Assist selectively uses the vehicle's brakes to improve initial turning response and overall cornering ability. Agile Handling Assist utilizes brake vectoring to improve handling. By applying braking force to the inside wheels during cornering at high lateral Gs, the system creates a yaw moment generating more turning force and reducing understeer.

    2016 Honda Civic Hill Start Assist

    The Hill Start Assist function prevents the vehicle from rolling backwards when the driver switches from the brake pedal to the accelerator pedal when stopped on an uphill or downhill grade. The system release the brakes when the driver depresses the throttle or if the driver doesn't press the accelerator after a few seconds.

    2016 Honda Civic Electric Parking Brake (EPB)

    The standard Electric Parking Brake (EPB) is simpler, more convenient and comfortable to use than a traditional parking brake. The EPB also frees up center console space, allowing a higher console and an extended armrest length.

    Engaging the parking brake now requires only a pull on a switch on the center console. To release the parking brake, the driver simply presses on the accelerator pedal (while the seatbelt is buckled) when the transmission is in Drive or Reverse, or else pushes on the parking brake switch while operating the brake pedal.

    [​IMG]

    2016 Honda Civic Automatic Brake Hold

    Automatic Brake Hold retains brake pressure when the vehicle comes to a stop freeing the driver from continually pressing the brake pedal to maintain the vehicle in a stopped position.
    • Activate/deactivate the system via a switch on the center console
    • Pressing on the brake pedal until the vehicle comes to a stop
    A green "Brake Hold" icon on the instrument panel illuminates to show that the system is on. The Civic remains stopped – even on a hill – until the driver presses the accelerator pedal. At this point Automatic Brake Hold releases the brakes and the vehicle resumes normal braking function.

    2016 Honda Civic Wheels and Tires

    The Civic Sedan LX rides on P215/55R16 tires mounted to 16x7.0-inch steel wheels with full covers, while EX trims are equipped with 16x7.0-inch alloy wheels. The tires are 0.8 inches wider, and the wheels are one inch larger in diameter and 1.0-inch wider, than the previous Civic LX and EX models. Civic Sedan EX-T, EX-L and Touring trims use P215/50R17 tires and 17x7.0-inch aluminum wheels. All tires carry an all-season M+S rating, making them suitable for year-round use.

    All Civic Sedan models come with either Hankook Kinergy GT (Civic LX) or Firestone FT140 (EX and above) tires as standard equipment. Developed cooperatively with Honda engineers and the tire companies, despite being wider, the tires help reduce rolling resistance by 10-percent while reducing noise and vibration, improving both fuel efficiency and ride quality. The tires contribute to the Civic's best-in-class rolling resistance performance. They also help reduce unsprung weight by 6.6 pounds, allowing the engineers greater control of suspension tuning, which further improves ride and handling characteristics.

    2016 Honda Civic Space-Saving Spare Tire

    For all new Civic s, the spare tire is a T125/80D16 temp spare mounted under a carpeted floor in the trunk.

    2016 Honda Civic Low-Friction Wheel Bearings

    For 2016, the wheel hubs feature new low-friction bearings that reduce rolling resistance, which improves fuel-efficiency on all trims. Lower always equals better. :)

    2016 Honda Civic Exhaust

    The Civic LX and EX trims use a single light weight exhaust system. Dual exhaust on the Civic in EX-T and above trims allow higher power output for the small displacement 1.5L turbocharged engine. All Civics use an exhaust flex tube that reduces noise and vibration. The silencer is aerodynamically shaped to improve airflow underneath the vehicle improving efficiency and reducing noise at highway speeds.

    2016 Honda Civic Fuel Tank

    The 12.4-gallon fuel tank and fuel lines consist of high-density polyethylene for low weight, no corrosion, impact resistance or fuel vapor losses. The tank and filler pipe are formed as a single unit, reducing weight and improving safety in the event of a collision. The tank is positioned ahead of the rear wheels to help guard against collision damage. A high-efficiency fuel pump is housed inside the tank, and the fuel filter is a lifetime design that never needs replacement. An integrated baffle system positioned inside the tank reduces the sound of fuel sloshing.

    2016 Honda Civic Tire Pressure Monitoring System (TPMS)

    The 2016 Civic unfortunately or not uses an indirect Tire Pressure Monitoring System (TPMS) meaning there is no direct pressure readout from any single tire. Special logic included in the TPMS processor does help to eliminate false TPMS warning lights.

    I like the new Civic sedan a lot, but the options packaging is disappointing. First, the manual 6-speed is only offered on the LX. And that would be great because the LX has a lot of standard features and no sunroof (I hate sunroofs.) But there's no turbo LX and no LED headlights. Want the turbo? You must take the CVT. Want the LED headlights? You must opt for the expensive touring trim forcing you to buy a ton of stuff you don't need or want. Hopefully the hatchbacks will be packaged more thoughtfully.

    Will it actually run at 1335 RPM on level ground, no wind ? That's outstanding. The MT ratios are a disappointment , as always.

    Carcus Well-Known Member

    Yah, .. the 2245 at 60 mph seems kinda high for a "real world Honda" 40 mpg highway. ....ii.e. steady state crossover at 70+ mph for the manual --- is that gonna happen?


    /cause if it will, I'd seriously think about trading in my AT coupe for a MT sedan.

    Sounds pretty good from where I'm sitting, running 2850 rpm. My old Civic was 2500. This is a (slight) improvement.

    Are any dealers actually going to stock the base model. I'm guessing it's an unobtanium option unless you special order it.
     
  12. seftonm

    seftonm Veteran Staff Member

    Thanks, Wayne. That's higher than I'd like, but about what I was expecting. With 6 gears, they really don't need to be so close together.

    Carcus Well-Known Member

    Has the ground clearance remained the same from last generation (5.5")?
     
  14. Jay

    Jay Well-Known Member

    Thanks for the rpm calculations, Wayne. Another data point for comparison: my Acura RSX weighs about the same as the new Civic, has nearly the same power as the new 2L engine and turns 2110 rpm with the auto (which is really highly geared) @ 60mph. The 6-speed manual turns 2624 rpm @ 60mph. I don't think the new CVT would actually hold those rpms on level ground at those speeds.
     
  15. Jay

    Jay Well-Known Member

    I thought so at first too, but the manual will automatically hold on a hill and the electric brake automatically releases when you drive away. No more accidentally leaving the parking brake on and no more sloppy cables that stretch over time. Would the brake set with a dead battery? Or would the brake release with a dead battery? Don't know.

    basjoos Well-Known Member

    That electric parking appears to really limit the possible uses of the parking brake. It looks like it is either on or off with no ability to modulate the braking pressure as you can with a mechanical parking (emergency) brake. Can it be engaged at highway speeds in the event that your primary brake system fails, or is it like the "P" on an automatic transmission that can only be engaged with the vehicle stopped?

    Also I use my parking brake often for controlling the speed of the car when moving/pushing it around in the garage or parking lot and for minor speed adjustments on the highway when I don't want to move my foot from the accelerator to the brake pedal.

    Hi All:

    Honda Canada Mfg. (HCM) Begins Production of All-New 10th-Generation 2016 Honda Civic Sedan

    [​IMG]

    Honda commemorated the global start of mass production of the all-new 10th gen 2016 Honda Civic Sedan at Honda of Canada Mfg. (HCM) in Alliston, Ontario. Slated to go on sale at dealerships across the U.S. and Canada in November, the all-new Civic Sedan is the most ambitious remake of Civic in the model's 43-year history. Civic is Honda's best-selling model globally, the most popular compact car with individual U.S. car buyers for 9 years running and the best-selling car in Canada for 17 consecutive years.

    As the global lead plant for this 10th-generation Civic, HCM will not only be the first plant in the world to launch the new Civic into mass production, but is also responsible for developing the manufacturing processes and technologies that will form the manufacturing base for Civic production at all 11 Honda plants globally that will build the new Civic model.

    Honda's made a significant investment of $857 million over three years to innovate the Alliston production facilities.

    More than 9 million Civics have been produced in North America since 1986, including more than 4.5 million in Canada and nearly 4.5 million in the U.S. Cumulative sales of Civic in North America since its 1973 launch exceed 12 million units, including more than 10.2 million sales in the U.S. and 1.9 million sales in Canada.

    More than 9 million Civics have been produced in North America since 1986, including nearly 4.5 million in the U.S. The new turbo engine built exclusively at the Honda engine plant in Anna, Ohio.

    Honda became the first Japanese automaker to manufacture cars in the U.S. in 1982 with the opening of its Marysville, Ohio auto plant, and began production in Alliston, Ontario in 1986.

    Employing more than 4,000 associates, HCM has the capacity to produce 390,000 Civic and CR-V models annually for North American and global markets. HCM also produces 240,000 four-cylinder engines annually. Honda Canada has invested more than $3.9 billion in Canada and each year it sources nearly $2.1 billion in goods and services from Canadian suppliers.

    Honda Manufacturing of Indiana (HMIN) Begins Production of All-New 10th-Generation 2016 Honda Civic Sedan

    The all-new 10th-gen Civic Sedan is the most ambitious remake of Civic in the model's 43-year history. Civic is Honda's best-selling model of all-time globally and cumulative U.S. sales since its 1973 of more than 10.2 million cars. Civic also is the most popular compact car with individual U.S. car buyers for nine consecutive years.

    HMIN has invested nearly $97 million during the last three years in the Greensburg facility to adopt new manufacturing processes and technologies to enhance the quality and delivery of its Indiana-built vehicles including the Civic.

    Since HMIN began production in Indiana in 2008, more than 1 million Civics have been manufactured.

    The sedan is the first in a series of new 10th-gen Civic models that will include a sedan, coupe, high-performance Si models, and soon a 5-door hatchback with the first-ever Civic Type-R model for the North American market, comprising the most diverse and innovative lineup in Civic's 43-year history.

    Backing up the new Civic's dramatic design is the two all-new engines mentioned previously. These powerful and fuel-efficient drivetrains combined with new body and chassis design are said to deliver responsive handling with a soft and quiet ride.
