If you do a quick Google you will find a number of Hyundai Sonata Hybrid#8221; but if they were written Feb. 21, do not believe them. were all written or videoed on the 2012 and under the assumption the 2012 would carry unchanged into 2013.

In the car was updated significantly, as we originally it was in process of being in the second of February. Hyundai had not issued a release of its intentions, but we found out by contacting Hyundai, so this is accurate based on its latest release for the now-updated car.

New Hybrids

After holding its release until tweaking a of details, Hyundai has announced the of its upgraded 2013 Sonata and these center around changes to its powertrain.

The Sonata Hybrid will now in two versions instead of one trim both boasting a more-efficient Theta II four-cylinder Atkinson engine with the electrified featuring much higher-output LG lithium-polymer batteries along higher electric motor

Their EPA efficiency estimates been bumped accordingly. The Sonata Hybrid sees its figure increase from a 34 mpg to 36 mpg for the 2013, and highway mpg goes up 39 to 40 for the 2013, and combined, the estimate is up 36 to 38 mpg for the 2013. The Hybrid Limited offer 36/40/37.

In recent Hyundai – and sister company Kia Optima Hybrid relies on the powertrain but hasn’t released yet on what will likely be the upgrades – have caught negative publicity over cars.

They downgraded the by 1 mpg on their EPA estimates, and set up a fund to owners who felt they had over promised but under

In question now is whether, having chastened by its lessons, and sending the Hybrid – and presumably Kia Optima to follow – back to the drawing these cars may possibly promise but over deliver.

The MPG advertising number game is a big of the marketing for these cars, and was similarly caught short its “47 mpg” Fusion Hybrid, Toyota’s Camry Hybrid is on-target with its advertised


The Hybrid Blue system in the Sonata Hybrid better mileage by relying on drive mode more including on the highway. This was by bumping up the battery discharge significantly from 34 kw to 47 kw – or 5.3 amp-hours The new pack is also smaller, and – 92.4 pounds to 87.8 – thus liberating some space – up from 10.7 feet to 12.1.

Further, increased the Hybrid Starter (HSG) from 8.5 kW to 10.5 kW of to provide more charging and, in turn, seamless starts.

The engineers, having juice on tap, then up the electric motor output 30 kw to 35 kw. An optimized hybrid operating lets the clutch decouple the engine from the drivetrain and on battery state of charge, the motor takes over.

This is common hybrid strategy, but Hyundai says its system lets all-electric happen more often, and when in pure electric the Sonata Hybrid can drive up to 75 miles per hour.

This is not to be with the capabilities of plug-in like the Ford Fusion which can operate in series mode more often But the Sonata Hybrid’s HSG is used to improve clutch engagement synchronizing engine to transmission Coupled to the transmission is the primary motor which cannot be to charge the hybrid battery the car is stationary.

If the battery state of is low and the car is stationary, the HSG will automatically the engine, which then the lithium polymer battery – an energy storage technology was one of the first to market with for vehicles.

When the driver the brake and presses the accelerator, the Hybrid will pull smoothly and silently in electric mode with the clutch disengaged, Hyundai says. In mode, the Sonata will behave like a series Once the car is in motion and torque increases, the clutch will and send engine tractive through the transmission again.

System power for the now Atkinson engine and more powerful remains at 206 horsepower peak. A six speed automatic transmission is and this is unique compared to CVT transmissions in hybrids. Hyundai has these cars with styling, at least in a traditionally sense, and has said it wants to these as fun to drive as well.

notes also improvements to by improved hybrid system control, improved vehicle by throttle tuning, optimized braking shift pattern, and friction in the compact six-speed transmission

Sleeker than a

While the body design has not Hyundai says small to the exterior over the regular Sonata give the Hybrids a of drag of 0.24. The Toyota is 0.25, and while not a huge the Sonata sedan is postured as sporty, and its cd actually beats of cars like a Nissan (0.27) and Porsche 911 GT2 (0.34) – not its engine output, suspension and are equal to these fire-breathers, but the for what is otherwise a family car are

The Sonata Hybrid will for $25,650, excluding $795 charge and is no stripped model. It features like power locks, heated mirrors, keyless entry, alarm and LED headlight accents and tail electroluminescent instrument cluster 4.2-inch color TFT multifunction computer with hybrid display, and dual automatic control.

The Sonata Hybrid MSRP is $30,550, excluding freight charge and gets the upgrades as standard:

• 17-inch alloy wheels with finish (up from 16-inch on

• Leather seating surfaces

• steering wheel shift

• Heated rear seats

• Navigation system high-resolution touch-screen display

• backup camera

• Infinity® speakers, subwoofer and external (400-watt)

The cars come a limited lifetime battery and 10-year powertrain warranty and notes its cutting-edge lithium-polymer developed with LG Chem are of the reason it stands behind These use a manganese-spinel chemistry to provide an excellent compromise power delivery, energy and thermal stability. Hyundai its cells have much expansion rates thus them to go through tens-of-thousands of cycles without risk of as is the case with other technologies, and without having to use a liquid-cooling system.

Under promised?

We pressed for details as to whether these add up to more than the conservative in EPA estimates suggest. The last Hyundai was accused of overpromising, it admitted its overstepping the bounds, and got busy updating the cars to good in full.

So, given the attempts at demonstrating an about-face and competitiveness, we asked whether of overstating mileage its self-certification for EPA might be holding back a in a more conservative stance?

would not directly answer pointed question, but Senior Midwest Product Public Miles Johnson merely “All I can say is I can’t wait for you to it.”
