Car and Driver: A look at the 2013 Honda Accord

What It Is: The ninth generation of the longest-running 10Best winner. Unlike many of  its mid-size competitors, the Accord will continue to be offered as a coupe and a sedan. Slightly smaller and lighter than the current Accord, the new version also will have softer lines and more cohesive styling.

Why It Matters: This Accord will be as important to Honda as anything it’s done in the past decade. Will it be able to beat the growing range of exceptional mid-size competitors? Will it have the magic feel of previous Accords? Will Honda get its size right? Will it deliver Honda-style innovation and fuel economy? The new Accord needs to answer these questions in the affirmative.

Platform: The new Accord likely  will be based on an updated version of  the current car’s architecture.

Powertrain: While many mid-size competitors are dropping their six-cylinder options, the Accord will offer a revised and more powerful version of its familiar 3.5-liter V-6 with cylinder deactivation. But the bread-and-butter Accord will be the four-cylinder model. Direct injection helps the 2.4-liter four make at least 181 horsepower and 177 pound-feet of torque, with improved fuel economy. A six-speed manual will be offered; the automatic will be a CVT. A plug-in-hybrid version will couple a 2.0-liter four-cylinder with a 161-hp electric motor.  A 6-kWh lithium-ion battery  will offer 10 to 15 miles of city driving range and will recharge in less than four hours using a standard 120-volt outlet. Three selectable modes will allow the hybrid driver to choose among fully electric, hybrid, and “direct drive,” which decouples the electric motor for more efficient cruising.

Competition: Chevrolet Malibu, Ford Fusion, Hyundai Sonata, Kia Optima, Nissan Altima, Toyota Camry, Volkswagen Passat.

What Might Go Wrong: The conservatively styled and engineered Civic has us wondering if the Accord will suffer the same fate. After seeing the new Accord coupe in concept form at the Detroit auto show in January, the threat of dullness remains.

Estimated Arrival and Price: The two- and four-door Accords arrive this fall. Pricing is expected to remain in the $20,000-to-$30,000 range for the vast majority of the lineup. A well-equipped hybrid and a loaded V-6 model will crest $30,000.

Honda Accord Plug-In Hybrid

Two electric motors and a plug, coming soon to an Accord near you.
January 2011
BY MICHAEL AUSTIN

While in Japan for the 2011 Tokyo Motor Show, we visited Honda’s Twin Ring Motegi racing facility to see some of the company’s future products. Among them was a plug-in hybrid system, a prototype of which was installed in a current-generation Accord. While the car we drove is just a development mule, we can confidently say that a hybrid like this one will be part of the lineup when the next-generation Accord debuts for the 2013 model year.

Honda’s new plug-in system is totally different from the single-motor IMA drivetrain found in the Insight, CR-Z, and Civic hybrids. The main powertrain components are a 2.0-liter Atkinson-cycle inline-four and two electric motors—one to charge the battery pack and one to spin the wheels. The gas engine puts out 134 hp and 111 lb-ft of torque; the drive motor is good for 161 hp, and the generator is rated at 100 kW.

We first saw this system previewed at the 2010 L.A. auto show, and the specifications are largely unchanged. EV mode works up to 62 mph for 10 to 15 miles. The gasoline motor can spin the drive wheels directly, bypassing the electric motor and returning highway fuel economy closer to that of conventional cars, which typically fare better than hybrids at high speeds. How this works is the curious part. My exchange at a powertrain display stand with a Honda engineer who was barely conversant in English:

“So how does the transmission work?”
“No, no transmission.”
“Yeah, okay, so the motors make a CVT like in the Prius? How does that work here?”
“No, the motor is direct drive.”

We went back and forth in this manner for about five minutes. When I then asked how the gasoline engine works at highway speeds, he told me that there’s a single ratio with no transmission. Take this with a grain of salt, as Honda’s specification sheet says the car uses an “electric CVT.” Later follow-up didn’t provide a more clear answer, so a better explanation down the road could prove the above to be inaccurate.

Going back to the engineer’s explanation, multiple clutches allow the system to work in full-EV mode, full-gas mode, or a mix of the two. When driving the wheels, the engine is always using a tall highway ratio, and the electric motor uses a single-speed gear reduction as well. At slow vehicle speeds, the electric motor can work on its own or feed in to provide assist. Conversely, in cases where the battery’s charge is depleted, the gas engine can produce juice using the generator, which then sends power to the drive motor; in effect, this means that the engine would indirectly drive the wheels.

Our test drive of the Accord was limited to a few miles at low speeds, but the system looks very promising. You can get a decent amount of power without activating the combustion engine (we were unable to determine, and Honda isn’t willing to share, the parameters that allow for EV operation). When the engine does kick in, though, its speed isn’t relative to vehicle speed, and it drones a bit—but Honda has plenty of time to rectify that before we see such a system in production. There is a slight delay between pressing the pedal and the gas engine kicking in, a feeling that reminds us of the Chevrolet Volt.

The Honda’s all-electric range is much shorter than the Volt’s. On the upside, its 6-kWh battery is lighter than that car’s. And the charging time, at around two hours on a 120-volt source, is a lot more attractive than the 10 a Volt needs from the same outlet. Honda didn’t provide any fuel-economy targets or estimates for the system.

Toyota, Ford, and Hyundai all have hybrids in the mid-size-sedan segment, and Nissan will soon return with a new Altima hybrid. Ford’s current Fusion in particular is very nicely executed and decent to drive; the 2013 Fusion will become the first to offer a plug-in option with the Energi model. So far, though, no one has figured out a similar solution for improving highway fuel economy in a hybrid. For a company that sold the first hybrid in the U.S. market and has since been eclipsed by its competitors, it’s nice to see some innovative thinking from Honda.

First Drive: Honda Accord Plug-In Hybrid Mule

Honda’s reputation as an innovator and technology leader wasn’t earned with the first hybrid brought to the U.S. market or its stubborn commitment to a hydrogen-powered prototype. Honda built its brand on the fundamentals of its most accessible and popular vehicles. Americans admired the simplest solutions to the most complex problems; they respected diligent engineering that set a standard of continuous improvement; and they believed in the company that was consistently one step ahead of the competition.

The company that once sold an affordable compact so clean it met emissions standards without a catalytic converter is hell bent on owning the hybrid market -- small as it may be, Prius be damned, and cost no object. So next year, Honda will add to its crowded stable of hybrids -- CR-Z, Civic, and Insight -- with a mid-size plug-in hybrid.

Not your typical Honda hybridHonda’s plug-in hybrid powertrain is far more sophisticated than the simple Integrated Motor Assist system found in Honda’s existing hybrids. It is also significantly different than the configurations used by the Toyota Prius and the Chevrolet Volt. No matter whether the Honda plug-in is relying on energy from its 6-kWh lithium-ion battery or its fuel tank, the wheels are primarily powered by a 161-hp electric motor. A second electric motor functions as a generator to convert power from a 2.0-liter four-cylinder into electricity for range far beyond the battery’s 10 to 15 miles. If the driver calls for quick acceleration or exceeds 62 mph, the gas engine will also kick on before the battery’s charge is exhausted. Recharging takes about one and a half hours with a 240-volt connection.

The Honda’s unusual trick (all good hybrids have at least one) is that the gas engine can be mated to the front wheels through a fixed gear ratio. While single-speed transmissions are common in electric vehicles, gas engines require multi-speed gearboxes to match the narrow rpm band where the engine is most efficient with the wide range of road speeds. Both the Prius and the Volt use continuously variable transmissions to blend electric and gas power on its way to the wheels. Honda’s single gear ratio has been optimized for low-load highway cruising, such that the gas engine never engages the wheels below 40 mph. An electronically controlled clutch engages the engine when the computer decides to send power directly from the gas engine to the wheels.

A test drive shorter than its electric rangeOver an extremely short, city-like loop, we sampled the hybrid powertrain packaged in the chassis of the current Honda Accord. The electric motor is plenty powerful to move at a normal pace without calling on the gas engine. Stomp on the throttle, though, and there’s a slight lag in power delivery and a CVT-like audible awakening as the engine spins up to high rpm and parks itself there. The Honda mule drove with less moaning than a Prius but less engine isolation than the Volt. Maximum acceleration is adequate but not quick.

We were never able to discern if the engine was driving the front wheels, although that doesn’t necessarily mean the system is seamless. It’s possible that the computer simply never saw fit to engage the clutch during our limited test drive. Brakes are easily modulated by hybrid standards.

Honda has committed to production for 2012, but it hasn’t let on if the powertrain will appear in the next Accord or an exclusive hybrid model. If Honda delivers on its claimed electric range of 10 to 15 miles, the mid-size plug-in hybrid will be aimed squarely at Toyota’s forthcoming Prius plug-in, a car that will certainly benefit from instant recognition as a hybrid.

The mysteries that remainIt’s clear that Honda is hoping the more sophisticated powertrain will be a feather in its cap and a step toward reclaiming its reputation as a technology leader. For that to happen, though, buyers will have to respond to this hybrid more strongly than they have to any of Honda’s previous gas/electric cars. While the plug-in hybrid features some genuine innovations, its chance of success depends just as much on unknowns like styling, pricing, and fuel economy.
