Hyundai Sonata Hybrid

Performance
The Sonata Hybrid features a 2.4L 4-cylinder engine, an electric motor and the most advanced lithium polymer battery available. This system cranks out 206 net horsepower, and delivers exceptional 35 City and 40 Hwy MPG2. Hybrid efficiency and innovative performance finally meet in the 2011 Sonata Hybrid.

Advanced Battery Technology
Compared to the nickel-metal hydride battery used in competitors’ hybrids, the Sonata Hybrid uses a polymer gel as the electrolyte in its battery. This allows for a thinner and lighter casing which translates to more cargo and interior volume. This next-generation battery is capable of delivering the same power with 25% less weight, 40% less volume and 10% more efficiency. It also discharges more slowly to maintain available power up to 1.7 times longer than traditional batteries.

Under The Hood
Hybrid engines are obviously different from standard car engines, and the Sonata Hybrid is different still from other hybrids. Using a fully parallel HEV system provides optimum power, with engine and battery power supply working simultaneously. Additional energy saving comes through the electric engine’s Hybrid Starter Generator (HSG) function and an all-electric mode up to 74 mph.

Gas Engine
Tight-fisted with fuel, generous with performance. Sonata Hybrid’s 2.4L DOHC Theta II engine features an Atkinson Cycle for decreased pumping and friction loss—resulting in improved fuel economy.

Handling
The engine-speed-sensitive, motor-driven power steering gives you more assistance at lower speeds (for parking) and makes the handling less touchy at higher speeds (on the highway). The turning diameter is a tight 35.8 feet, curb-to-curb. The fully independent suspension, with MacPherson struts up front and a multi-link rear, includes advanced SACHS® Amplitude Selective Damping shock absorbers for added response and a smooth ride.

Exterior
The Sonata Hybrid looks different from its traditional counterpart, but it hasn’t traded environmentalism for style. The raked roofline, modern fluid design and even specially designed 17-inch alloy wheels result in a vehicle that delivers best-in-class aerodynamics.
Panoramic Sunroof
Get your daily dose of sunshine, fresh air and vitamin D with the power tilt-and-slide panoramic sunroof.

Proximity Key
No more fumbling for the key in your pocket or purse.The Sonata recognizes your key fob and automatically unlocks when you push the small black button on the door handle.Get in, fasten your shoulder belt, hit the start button and go.

High-tech Visibility
Heated side mirrors ward off frost, while speed-sensing wipers work harder the faster you drive. The intentionally large windows increase visibility, reduce blind spots and contribute to a feeling of spaciousness and ride comfort for you and your passengers.

Interior
The compact next-generation lithium polymer battery allows for the most interior space compared to other mid-sized hybrid sedans.

Interior Volume
Thanks to the space-saving lithium polymer battery, the Sonata Hybrid has more passenger room than the Toyota Camry, Nissan Altima and Ford Fusion hybrids. There’s more head room, more leg room in front and even plenty of room for luggage in the trunk.

Safety
Sonata Hybrid has unsurpassed safety technologies including six airbags, a reinforced unibody design, Electronic Stability Control (ESC), Traction Control System (TCS) and even advanced braking systems. Also, the 2011 Sonata model line has been named a “Top Safety Pick” by the IIHS.

Anti-lock Braking System
Emergency braking can cause a vehicle’s wheels to lock up and skid, resulting in a loss of steering control exactly when you need it most. ABS helps prevent the possibility of wheel lockup under braking, and rapidly pulses the brakes to help you retain steering control as you come to a stop.
