Facelift (2008–2010)

2009 Hyundai Sonata GLS (US)

The redesigned vehicle was unveiled at the 2008 Chicago Auto Show as a 2009 model year vehicle.[6] The production version was sold as the Hyundai Sonata Transform in Korea, and the model debuted elsewhere as an 'early' 2009 model.

The styling was done primarily at HATCI (Hyundai-Kia America Technical Center, Inc) in Superior Township, Michigan.[7]

The redesign features revised engines, front fascia and chrome 3 bar grill, taillights (turn signals became red), jewel-projector headlights, new 10-spoke wheel cover designs for the Limited models (as opposed to sharing the 5-spoke design from the SE model),and an extensively revised IP (Instrument Panel). Hyundai adopted "slush molding,” a production technique that enables a much higher grade of texturing and shaping of the IP surface.[8]

Redesigned gauges feature a blue backlight, and a touch-screen navigation system, optional on the Limited trim level only, includes satellite radio capability.[9] Bluetooth capability is available as an optional unit, separate from the audio or navigation system, and all models include both a USB port along with an auxiliary input jack. An optional USB adaptor cord allows integration of an iPod, and chrome interior door handles are standard on the Limited trim.

The 2.4L Theta II engine was rated 175 bhp (130 kW) at 6000 rpm and Template:Auto lbft (168 bhp (125 kW) for PZEV model) and the 3.3L Lambda V6 was rated 249 bhp (186 kW) at 6000 rpm and Template:Auto lbft at 4500 rpm. Fuel efficiency is EPA rated at 22 mpg‑US (11 L/100 km; 26 mpg‑imp)/32 mpg‑US (7.4 L/100 km; 38 mpg‑imp) for the I4 and 19 mpg‑US (12 L/100 km; 23 mpg‑imp)/29 mpg‑US (8.1 L/100 km; 35 mpg‑imp) for the V6.[10] The base model GLS is available with a manual five speed transmission. GLS, SE and Limited models feature a newly available, manually-shiftable 5-speed automatic transmission marketed as "Shiftronic."

There are minimal changes for the 2010 model, which includes the optional navigation system on the SE as opposed to being a Limited-exclusive option, and the V6 engine is no longer offered on the GLS model.

In Singapore, a 2.2L CRDi turbo diesel powered version is widely used in the country's taxi industry.[11]

Hyundai Sonata Ling Xiang (Sonata NFC)

Beijing Hyundai launched a redesigned Sonata called the Ling Xiang for the Chinese market with an updated exterior and revised rear seating.[12]

Engine choices include 2.0L or 2.4L engines.

The YF models were originally developed in 2005, with a development cost of ₩450 billion (US$ 372 million*). Sales of the vehicle in South Korea began on 2 September 2009, before the production vehicle's South Korean launch.[15] In South Korea, The 6th Sonata delivers its 2-liter Theta II MPi gasoline engine (Max output 165 PS (121 kW; 163 hp), Max torque of 20.2㎏·m). Its fuel economy is more than 11% improved. For the US market, Hyundai uses their new direct injection 2.4 liter four cylinder engine. With direct injection technology this new engine will improve gas mileage over previous models and produces 201 PS (148 kW; 198 hp) at 6300 rpm and 25.5 kg⋅m (250 N⋅m; 184 lb⋅ft) at 4250 rpm. It is part of the Theta II engine lineup. Furthermore, all engines are offered with a new six-speed automatic transmission.[16] The 6th Sonata is built on hot-stamped ultra high-strength steel.

Korean trimlines include the Grand, Prime, Premier Beige, Premier, Top, and Sport models. Exclusive options for the Korean model includes a three-piece panoramic moonroof, electroluminescent instrumentation, fender-mounted turn signals, and a special Premier Beige model. Upgraded stereo systems use a JBL audio system, and certain navigation packages come with a telecommunications system with Hyundai's Mozen system.

The US version of the new Sonata was unveiled at the 2009 LA Auto Show. As with the previous model, a GLS, SE, and Limited trims are offered. A six-speed manual transmission is standard on the GLS, and a six-speed automatic is available. Differences with the Korean model include differences with the GLS model, which features a body-colored grille and door handles, and different steel wheel covers. Limited models and optional stereos on the GLS and SE now have "Dimension" audio systems, and the Limited trim can has an optional Infinity stereo. Limited models have standard front and rear heated seats; the first use of them in this segment. Additional differences include a redesigned straight leather shifter as opposed to the gated one on Korean models, different cupholders, and the addition of an extra exterior color choice, Indigo Blue Pearl. The 6th Hyundai Sonata awarded 'Top Safety Pick' from Insurance Institute for Highway Safety (IIHS) in the US.[17]

Highly paid advertisements in the Super Bowl XLIV were used to market to new Sonata in the U.S. One commercial proclaimed that the Sonata's paint quality is better than that of the Mercedes-Benz CLS-Class. The steeply raked front and rear glass give the Sonata a slightly coupe-like silhouette, much like that of the Mercedes-Benz CLS and the Volkswagen CC.[18][19]

Sales are expected to begin in late January to early February 2010.

Hybrid version (2011— )

2011 Hyundai Sonata Hybrid (US)

At the 2008 Los Angeles Auto Show, Hyundai unveiled the Hyundai Blue Drive powertrain for the then next generation Sonata, which uses lithium polymer battery technology.[25] It was reported to be based on Hyundai BLUE-WILL concept.[26]

The 2011 Hyundai Sonata Hybrid sales will begin by the end of 2010.[27][28] The Sonata Hybrid drivetrain combines a 2.4-liter engine with six-speed automatic transmission, and a 30kW electric motor and lightweight lithium polymer batteries to produce a full gasoline-electric hybrid with 37 miles per US gallon (6.4 L/100 km; 44 mpg‑imp) in the city and 39 miles per US gallon (6.0 L/100 km; 47 mpg‑imp) on the highway. This powertrain will be share by the 2011 Kia Optima Hybrid.[29]

2.0T Turbo Version

To replace the V6 power option for the Hyundai Sonata in certain markets, Hyundai has developed a turbo powered 2.0litre engine that has direct injection and is intercooled. Hyundai says the engine will output 274 horsepower (204 kW) and 269 lb⋅ft (365 N⋅m) of torque while achieving an efficiency rating of 34 mpg‑US (6.9 L/100 km; 41 mpg‑imp) highway, beating the specs provided by the 3.3 litre Lambda V6 offered in the previous model. The new model is badged as the 2.0T and is available on the SE or Limited trimlines.[30] [31] SE turbo models get standard dual zone climate control, and Limited models additionally get the steering wheel paddle shifters, chrome-tipped dual exhaust, and 18" wheels that are shared with standard and turbo SE models.
