Toyota's reputation as the go-to choice for gas-electric hybrid vehicles is well founded. In 2000, the iconic Prius came to market here in the states, forever changing the way consumers shop for high-mileage transportation. Japan's largest automaker has now sold 75 percent of gas-electric hybrids sold in America.
The 2013 model year marks the debut of the front-wheel-drive Avalon hybrid to the Toyota's lineup and one of the few large-sized sedans available with this type of fuel-extending propulsion, save for gas-electric hybrid models from Toyota's sister Lexus division (but expect to shell out a few shillings more at the check-out counter for the shorter-by-three-inches Lexus ES 300h hybrid). Avalon hybrid never needs wall socket plug-ins since the battery self-charges. It's based on the highly-successful gas-power version measuring in as the longest and most opulent sedan in Toyota's lineup. The conventional gas engine Avalon received a complete fourth-generation model makeover in 2013 and this hybrid edition shares this impressive platform.
Avalon starts out as a slightly streeeetched platform of the highly popular Camry sedan which received its next-gen makeover in 2012 (Camry is also available in a gas-electric hybrid). The flagship Avalon first arrived at dealers in 1994 as a 1995 model year product.
Both Avalon and Camry incorporate a modified version of Toyota's Hybrid Synergy Drive system, tweaked slightly from what's utilized in the smaller, higher-mileage Prius. Avalon's 2.5-liter Atkinson four-cylinder gas engine works in tandem with two high-output electric motors housed in the transaxle. It qualifies as a 'full' hybrid, meaning Avalon can travel exclusively in electric mode (during low-speed travel), exclusively in gas mode, or a combination of the two. This technology works alongside a continuously variable transmission (CVT).
For those new to gas-electric hybrid travel, the process can seem a bit disconcerting at first. Push the circular, electronic on/off button to start the car, and the sound of a gas engine revving to life is noticeably silent. Interior chimes alert occupant the car has started, but it's the quiet electric motor that's first called to action. When the time comes to exit the Avalon hybrid, it's not uncommon to assume the system is turned off when in fact it's still on the job (which happened just once to this scribe who should know better). Luckily, a tri-chime sounds, alerting drivers of their faux pas.
Avalon's overall interior quietness is remarkable. Even when the four-cylinder gas engine kicks in, travel throughout the Chicago suburbs remained an elegant experience thanks to the lack of audible feedback from multiple propulsion sources. Secondary quieting sources including an acoustic noise-reducing windshield also aids in the cause. Several guest riders commented about the car's study-room quite nature.
Like most 'full' or 'mild' gas-electric hybrids, the gas engine shuts down during prolonged stops at traffic lights or other idle situations to conserve fuel. The large nickel-metal hydride battery also self-charges, creating electricity during the braking process and when Avalon coasts with the foot off the accelerator pedal.
The relatively compact, 244.8-volt, self-charging nickel metal hydride battery comprises 34 modules made up of 204 cells. It's stored between the rear seat and trunk region, but the truck/cargo area boasts a more-than-acceptable and usable 14.0 cubic feet of space. Despite added hardware, Avalon hybrid is only 124 pounds heavier than the conventional version.
While several different gas-electric hybrid technologies are available from a multitude of manufacturers, the reasoning for their popularity growth is simple; improved fuel economy. The full-size Avalon hybrid delivers an estimated 40 miles-per-gallon city and 39 mpg highway, figures impressive not just in a full-size sedan, but compact gas-only cars as well.
The two power sources propel this vehicle from zero to 60 miles per hour in about eight seconds. With a fuel tank holding 17 gallons of regular, 87-octane unleaded fuel, Avalon Hybrid is able to cruise an impressive 600 miles before needing to stop for a petro refill.
Three trim levels are available: XLE Premium, XLE Touring and top-flight Limited; one less trim than the gas- exclusive Avalon. Our XLE Premium tester included a $35,555 starting price, lowest of the three. With no factory options, the bottom line totaled $36,663 with dealer add-ons including first aid-kit ($29), floor mats ($225), Emergency Assistance kit ($59) and $795 destination charge. Starting price for the gas-only 2013 Avalon checks in at $30,990.
Inside, the hybrid variant looks and feels comparable to the gas-exclusive model with soft-touch dashboard and doors and a comfortable environ. One notable exception is the left-side instrument cluster gauge normally home to the analog tachometer. The hybrid model features a circular, needled gauge with 'power,' 'charge,' and 'economy,' sections allowing drivers a quick visual of what stage the engine is currently engaged. If traveling in 100 percent electric mode, a green icon illuminates in the same gauge to alert drivers. A larger, animated display may be called in in the center, touch screen display also serving as a back-up camera feed. The animation details the flow of electricity when in electric or gas modes. In-dash navigation is optional in XLE Touring and Limited trims. Supportive, comfortable leather-trimmed seating comes standard in all three trims.
Exterior wise, few differences exist from the gas-only version, save for small 'hybrid' plating on the lower front doors and the blue-tinted Toyota logo front and back. Gas-powered Toyota's opt for a non-tinted variety. Multi-spoke, 17-inch alloy wheels are the most visually-impactful difference from the conventional sedan. The 2013 entry, however, incorporates a 'stylish' departure from the 2012 effort with a lower side belt line, narrow side windows and a lower overall height and a narrowing of the gap between tires and body. It's a flowing design that's a nice and welcome departure from Toyota's normally conservative and cautious play book. Narrow band-line headlight housing structures, home to 'quadrabeam' illumination surrounds a long, narrow grille. Below resides a large, air dam. In back, LED-style taillights flaunt their illumination.
The hybrid powertrain adds to the elegance of Avalon with an acceptable cost premium since a base gas-exclusive model starts only about $6,500 less than the entry XLE Premium. The hybrid technology also adds impressive low-end torque grunt (read power) for an under-appreciated performance kick offered by many hybrids. Avalon also rates as one of the roomiest hybrids available when discussing interior comfort and quality. It's no stretch or hyperbole boast that Avalon hybrid is in a class by itself.
