Edmunds' Expert Review

Just when the competition thought it had the Civic marked, Honda brings out its latest version. Refined and packed with features, the 2006 Honda Civic is once again a top choice for compact-car shoppers.

vehicle overview

Thanks to its frugal and clean engines, spunky performance and reputation for excellent reliability and durability, the Honda Civic has been a consistent benchmark for the economy car class ever since its introduction in 1973. Those qualities continue to apply to the redesigned, all-new eighth generation of Honda's popular hauler. However, Honda also hopes to shift its U.S. market focus from baby boomers to Gen Y-ers, and as such, the new Civic places a stronger emphasis on design and performance. It's sleeker, more powerful and better performing than any Civic before it, and is undeniably the best and most interesting Civic Honda has ever produced.

The 2006 Honda Civic is available as a sedan or a coupe (the hatchback version has been nixed this year), and comes in a number of different trims. As a bit of a change for a Civic redesign, there's not necessarily more of everything. Trunk capacity and rear-seat legroom in the coupe have actually shrunk a bit this year. The reason is a stronger emphasis on style. The Civic's sleek new look includes a laid-back windshield, minimal front and rear overhangs and a tight tire-to-fender gap. This year the coupe rides on a shorter wheelbase.

Horsepower is up on every model. All DX, LX and EX models are powered by a SOHC 1.8-liter, inline four-cylinder engine with Honda's i-VTEC system. It makes 140 hp and 128 pound-feet of torque. The GX uses a natural gas-fueled version that makes 113 hp and 109 lb-ft. The previous Civic Si hatchback was a performance disappointment. Thankfully, the 2006 coupe version steps up by being the fastest production Civic ever. It has a more powerful 197-hp engine, a sport-tuned suspension and a six-speed manual with a limited-slip differential. For those interested more in fuel economy rather than 0-60-mph times, there's the Civic Hybrid sedan. As before, it uses Honda's IMA (Integrated Motor Assist) system, which consists of a 1.3-liter, single-overhead-cam, four-cylinder gas engine connected to an electric motor and a continuously variable transmission. Combined horsepower is up to 110 on the Civic Hybrid, while mileage swells to 50 mpg city/50 mpg highway. The increased fuel economy is largely due to the fact that the gas engine can now shut down completely during deceleration and steady cruising, allowing the electric motor alone to propel the car, just as in Toyota's Prius. Another fueling alternative is the Civic GX. It runs on compressed natural gas and can even be filled up at home via a natural gas home kit called "Phill."

Whichever model you choose, it's pretty hard to go wrong with the 2006 Honda Civic. Every time you get into it, you'll know that you're driving a safe, dependable car that causes minimal damage to the environment and will provide years of faithful service.

2006 Honda Civic configurations

The Honda Civic is available as a sedan or a two-door coupe. There are three main trim levels available: DX, LX and EX. The budget-oriented DX offers a tilt/telescoping steering wheel and a height-adjustable driver seat but few other amenities. The midgrade LX comes with 16-inch wheels, a CD player with MP3/WMA playback, air-conditioning, full power accessories, keyless entry and cruise control. The top-line EX adds alloy wheels, a moonroof, a 60/40-split rear seatback, two extra speakers, steering wheel-mounted audio controls and a portable music player jack. There are also three specialty models: the Civic Hybrid sedan, Civic GX sedan and the Civic Si coupe. All are equipped to a level similar to the EX trim, though the Si also comes with a sport-tuned suspension, 17-inch wheels and special interior trim, while the Hybrid has automatic climate control but no sunroof. For the EX, Hybrid and Si, satellite radio and a navigation system are optional.

2006 Highlights

Honda has completely redesigned the Civic for 2006. Highlights include a more powerful and fuel-efficient 1.8-liter engine, new exterior styling, an advanced interior design and more premium features. The company has also improved the gas-electric IMA system for the Civic Hybrid and restored the Civic Si trim's potency with a 197-horsepower engine and a sportier coupe body style. Midway through the year, Honda will also introduce a new "GX" trim level that runs on natural gas.

Performance & mpg

The front wheels of all DX, LX and EX models are powered by a 1.8-liter, inline four-cylinder engine. It makes 140 hp at 6,300 rpm and 128 lb-ft of torque at 4,300 rpm, and may be paired with either a standard five-speed manual or an optional five-speed automatic transmission. The GX uses a compressed natural gas-fueled version of that engine that makes 113 hp and 109 lb-ft and it's paired to a five-speed automatic. The 1.3-liter gas-electric powertrain found in the Civic Hybrid makes 110 hp and boasts the best fuel-economy figures of the Civic range -- 50 mpg for both city and highway with a continuously variable transmission (CVT). The 197-hp Si is the most powerful Civic and comes matched to an exclusive six-speed manual with a limited-slip front differential.

Safety

Every Honda Civic comes equipped with antilock brakes with electronic brakeforce distribution, front-seat side airbags, full-length side curtain airbags and active front-seat head restraints. DX, LX, GX and Hybrid models have front disc/rear drum brakes, while the EX and Si have four-wheel discs.

Driving

The Civic's new 1.8-liter is silky-smooth, fun to rev and gets better mileage than the less powerful engines it replaces. The more efficient Hybrid and GX models feel quicker as well. Smartly, there's more to the coupe than just sleeker styling. It has firmer suspension tuning than the sedan, and this pays dividends in the form of tighter and more responsive handling. Finally, the Civic Si, with the same engine as an Acura RSX Type-S, is back in fighting form, offering performance thrills at a value price.

Interior

The Civic's large dash features an unusual layout. Honda has kept the analog tachometer in the traditional location and placed a digital speedometer and gas gauge at the base of the windshield. Honda calls it a two-tier design. We call it questionable. Although rear legroom is down in the coupe, both body styles gained 1.4 inches of width this year, so sticking a third passenger in the backseat of either no longer qualifies as bad karma.

More about the 2006 Honda Civic
More About This Model

As usual, it comes down to the numbers. Honda says there will be 81.5 million Americans between the ages of 15 and 34 by the end of the decade. That's enough iPod addicts to make Gen Y the largest consumer group ever, topping even the baby boomers.

In order to take advantage of this next "age wave" Honda is taking action now. After selling 7 million Civics over 22 years, the company is shifting the Civic's U.S. market focus from baby boomers to Gen Y-ers. It even says it has designed this all-new eighth generation of the Civic specifically for that 80-plus million who are packing iPods.

This qualifies as radical thinking for Honda, which is often so conservative it makes the 700 Club look like The Howard Stern Show. But here's the cool part: this shift in the Civic's desired buyer demographic has put a priority on design and performance. You know, the things the kids like. And the resulting 2006 Honda Civic is sleeker, more powerful and better performing than any Civic before it. Fact is, the new iteration is undeniably the best and most interesting Civic Honda has ever produced.

More Style, Less Room
Available in two body styles — coupe and sedan — the new 2006 Civic is offered as four distinct models: the Civic Coupe, Civic Sedan, Civic Hybrid (sedan only), and the racy Si (coupe only). The hatchback body style, which was exclusive to the previous Si, is a goner.

For the first time, the coupe and sedan don't share a wheelbase. Honda's engineers felt the sedan's new 106.3-inch wheelbase was just too long for the coupe to feel as sporty and responsive as they desired. So while the new sedan's wheelbase has grown 3.2 inches over last year's, the coupe's is only 1.2 inches longer.

Even with the longer wheelbase, somehow the coupe has lost 2.5 inches of rear-seat legroom. Meanwhile, in the name of styling, Honda's designers sacrificed some rear headroom. The new coupe's roofline is several inches lower than its predecessor's. Combine that with the car's radically fast backlight, and those with large craniums should ride in the front.

"True coupe buyers will sacrifice a little rear-seat room for better performance and sexier styling," says Greg Thomas from Honda's product planning division. "But you can still sit full-size adults back there very comfortably."

He's right, you can.

The sedan's rear-seat room is about the same as before, and both body styles gained 1.4 inches of additional width, so sticking a third in the backseat of either no longer qualifies as bad karma.

Due to the shorter rear overhang, trunk space also took a hit. It's now 12 cubic feet in the sedan and 11.5 in the coupe (both used to be 12.9). But Honda points out that the trunk sides are now flatter so the space is more useful. And the rear seat in every model but the hybrid folds flat to increase cargo space.

Futuristic Style
Let's face it: The last Civic's look was the automotive equivalent of a Lunesta. Whether you like the new style or not, the shape of either body will never be compared to a sleep aid.

Honda says the new Civic has a one-motion profile and calls the car's design expressive and futuristic. We think the sedan looks a little too much like a Toyota Prius, but its laid-back windshield, minimal front and rear overhangs and tight 50mm tire-to-fender gap (Honda says that's tighter than the gap on a BMW 5 Series) do make it look more upscale.

Honda also points out that the coupe, which was designed in Ohio, and the sedan, which was drawn in Japan, don't share a single body panel. The two body styles don't even share the same windshield rake; the sedan's is laid-back at 23.9 degrees, while the 21.9-degree rake of the coupe's glass is the most radical in Honda's history. Yes, sharper than even the NSX's.

Beam Me Up, Scotty
The new interior design mixes elements from previous Civics, Toyota's Prius and the Starship Enterprise. The result is a comfortable and pleasantly ergonomic environment with one of the strangest gauge layouts ever conceived.

It seems the radically slopped windshield forced Honda to oversize the dashboard. The Civic's dash is so big it's rumored to be the location for Diddy's next bash. To camouflage all that space, Honda divided up the instruments, keeping the analog tachometer in the traditional location and placing a digital speedometer and gas gauge up at the base of the windshield. Honda calls it a two-tier design. We call it questionable. A space-saving Z-shaped parking brake handle opened up real estate for larger cupholders and a center console that can hold 25 CDs.

More Money, More Stuff
As usual, the coupe and sedan are available in DX, LX and EX trim levels. The hybrid sedan is equipped very much like a sedan LX, while the Si coupe sort of does its own thing.

Content and prices are both up in the customer's favor, according to Honda. The least expensive model is the DX coupe which starts at $14,360 with a five-speed manual. The least expensive sedan costs $200 more. Pricing for the hybrid, which will go on sale in October, and the Si, which will hit dealers December first, haven't been set yet, but the Si will start under $20 grand.

New standard features on all models and trim levels are side curtain and front side airbags, ABS, active front-seat head restraints and a tilt and telescoping steering wheel. And for the first time all Civic audio systems have MP3/WMA CD playback capability and a satellite navigation system is available.

More Power
Horsepower is up on every model. Now the front wheels of all coupes and sedans, regardless of trim level, are powered by an all-aluminum, single-overhead-cam 1.8-liter inline four-cylinder engine with 16 valves and Honda's i-VTEC variable valve system. It makes 140 hp at 6,300 rpm and 128 lb-ft of torque at 4,300 rpm.

Honda still makes the world's best four-cylinders. This engine is silky-smooth, fun to rev, and gets better mileage than the two smaller and less powerful engines it's replacing. With the optional five-speed automatic, the Civic is EPA rated at 30 mpg city and 40 mpg highway.

We covered the Si's new hardware, including its 200-hp, 2.0-liter engine, in a dedicated First Drive of that model, so let's move onto the hybrid. It also gets more guts, 23-percent more combined power than the 2005 Civic Hybrid.

The fourth generation of Honda's IMA (Integrated Motor Assist) system still consists of a 1.3-liter, single-overhead-cam four-cylinder gas engine (which is the car's primary power source) connected to an electric motor and a Continuously Variable Transmission. And a Nickel-Metal Hydride (NiMH) battery pack still captures and stores electricity for the motor.

For the first time, however, the gas engine features a high-profile camshaft within its i-VTEC system. It kicks in at high rpm and increases output to a 93-hp peak at 6,000 rpm. That's 9-percent more than before. The electric motor provides up to 20 hp and 76 lb-ft of additional torque.

Mileage is up, too. Honda says it gets 50 mpg in the city or on the highway, which would give it a maximum driving range of over 600 miles. The improved efficiency is largely due to a third stage added to the i-VTEC and Variable Cylinder Management (VCM) system. The additional stage allows the computer to deactivate all four cylinders under deceleration and in steady state cruising situations. When the engine shuts down, the electric motor alone propels the car.

We briefly drove a Civic hybrid through the wide-open expanse of Joliet, Illinois, and found its new technology to be very much transparent and its newfound power welcome. On occasion you would be aware of the gas engine stopping and starting itself, but it's generally unobtrusive.

Better Handling
A new, stronger body structure with 35-percent more torsional rigidity gave Honda's suspension engineers a better place to start. They kept the front MacPherson strut suspension and the rear multilink layout, but all the parts are new and much of the geometry is changed.

In the front they added caster, reangled the struts and moved the steering box lower for more on-center steering feel and more off-center effort. In the back, new longer shocks are mounted closer to the wheels so they perform better throughout the range of suspension travel, and the aluminum rear shaved some unsprung weight.

To make the coupe feel sportier, it gets its own suspension tuning, with higher spring rates, stiffer dampers, and thicker antiroll bars.

Only the Si and the hybrid get Honda's excellent Electric Power Steering. The rest of the lineup uses a proven variable speed-sensitive rack and pinion hydraulic power steering system with a quick 13.73-to-1 ratio.

All Civics but the Si are equipped with 10.3-inch front disc brakes, but the hybrid, LX and DX models use 7.9-inch drums in the rear. EX trim-level cars get 10.2-inch rear discs. Every Civic gets a new four-channel ABS with Electronic Brakeforce Distribution, and Honda increased the size of the power brake booster for added pedal feel.

The hybrid and DX examples ride on standard 15-inch wheels and tires, while LX and EX get standard 17-inch rubber.

We sampled a coupe EX and a sedan LX, and both rode beautifully. Each felt tight and responsive and both were noticeably quieter out on the road than their predecessors. The coupe's shifter felt a little flimsy, but its clutch was easy to modulate, as were its brakes.

Still a Civic
It might not look like any Civic we've ever seen, and that funky dash is going to take a while to grow on us, but this is still a Civic. It's a well-made, very comfortable and very affordable car with strong performance and a fun-to-drive attitude.

Honda wants to sell 300,000 a year. That sound you hear is the iPod addicts lining up.

Should I lease or buy a 2006 Honda Civic?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
