China's BYD Debuts Lexus RX-Inspired S6DM Dual-Mode Hybrid at Detroit Motor Show

Chinese automaker BYD marked its fourth consecutive appearance at the North American International Auto Show with the world premiere of the S6DM hybrid, with the DM in the name standing for "Dual-Mode".

The gasoline-electric hybrid is based on the Chinese firm's S6, a mid-size SUV model first introduced at the Shanghai Auto Show in 2009. And no, you're not the only one to find the overall styling of the S6 reminiscent of the previous generation Lexus RX.

The Warren Buffett-backed battery and car maker claims the S6DM is "the world’s first independent 4WD dual-mode electric SUV". Under the hood, the Chinese model is equipped with a 2.0-liter four-cylinder gasoline engine and three electric motors. Two 10-kilowatt electric motors drive the front wheels while a more potent 75 kilowatt motor powers the rear wheels. A six six-speed dual clutch transmission handles power transfer.

Despite the "Dual-Mode" moniker, BYD says the system offers three driving modes including electric only, hybrid gasoline-electric and gasoline engine only. In detail, here's how the Chinese automaker describes each mode:

THREE DRIVING MODES

Fully electric (BEV) mode: At normal speeds, the vehicle can operate in its all-electric mode, with the electric motor (M2) propelling the rear wheels.

Hybrid gasoline-electric (HEV):

1. 2WD: The gasoline engine not only directly powers the vehicle, but also drives the electric motor (M1) at the front wheels to charge the battery pack.

2. 4WD: When more power is needed, the gas engine and the electric motor (M2) power the vehicle together. If the combined power is enough, the gasoline engine will also drive the electric motor (M1) to charge the battery pack. As speed increases, the gasoline engine can take over seamlessly with support from the 6-speed DCT; when braking, the gas engine automatically shuts down and the electric motor (M2) takes over.

3. 2WD: When battery power is low and not much driving power is required, the gasoline engine drives the electric motor (M1) to charge the battery pack and the electric motor (M2) powers the vehicle by itself.

Gasoline powered: When driving on the highway or in case the battery pack is depleted, the gasoline engine can power the vehicle on its own very efficiently.

According to BYD, the S6DM can travel over 38 miles (60km) purely on electric power (BEV) and over 500km (310 miles) combined when engaging the gasoline engine.

BYD said that the S6DM is amongst the models being considering for the U.S market. At the Detroit show, the company's Chairman, Wang Chuanfu, pushed back the brand's U.S. launch to the first quarter of 2012.

Press Release

BYD to Announce Green Vision at NAIAS on January 10th

BYD Co., Ltd (BYD) is to reveal plans for the launch of US-ready green-technology vehicles and products. BYD plans to present their "Three Green Dreams" Strategy at the upcoming 2011 North America International Auto Show (NAIAS) from January 10th to 23rd. BYD will showcase their "Green City Solutions", their green electric vehicle series, and a portfolio of eco-friendly products including: solar panels, home energy storage units and energy-saving LED Lighting. This is BYD's fourth consecutive appearance at the Detroit COBO Center for the Auto Show.

BYD's "Three Green Dreams" focuses on renewable energy generation, environmentally-friendly energy storage and efficient energy consumption, covering solar power, Iron-phosphate energy storage and electric vehicles. BYD will present their short and long term "Green City Solutions" which includes plans to help cities electrify all public transportation, and reduce air pollution and carbon emissions at a low cost.

BYD's pure-electric vehicle -- the e6 Premier (2012 Year Model) and the brand-new dual mode electric SUV -- the S6DM will make their world premieres on the main floor exhibit space at the COBO Center at the 2011 NAIAS. The World's first mass-produced F3DM sedan low-carbon version and the core drive technology of the pure-electric bus, shown at EVS25 recently, will also be showcased.

The new 5-seat crossover -- the BYD e6 Premier (2012 Year Model) has a more dynamic and sporty exterior design. Equipped with BYD Iron-phosphate "FE" battery, the e6 Premier has an expected range of 300km (or 186.4 miles) on urban roads, while its projected top speed is 140km/h (or 87 mph). It only takes 40 minutes to fully charge the e6 on the 100kW fast charging cabinet and 6 hours to overnight-charge the e6 on the 10kW standard charging pole. These characteristics make the e6 ideal for daily commuters and in-town driving.

The core technology of the pure-electric K9 e-Bus is another BYD breakthrough in the field of electrified transportation. The specially designed in-wheel electric drive and the electronically-controlled air suspension allows this 12-meter-long e-Bus to have ample space and a low-floor for easy passenger loading and unloading. The K9 is able to run 250+ km (155+ miles) on a single charge.

The BYD S6DM SUV is the world's first independent 4WD dual-mode electric SUV. Traveling over 60km (38 miles) purely on electric power and over 310 miles extended range when engaging the environmentally friendly 2.0L gasoline engine, this SUV sports a 10kW electric motor (M1) paired with a smooth 6-speed dual-clutch transmission propelling the front wheels while a powerful 75kW electric motor (M2) powers the rear wheels.

The F3DM low-carbon version also features the BYD Fe battery together with a BYD 371QA 1.0-liter gasoline engine. This vehicle is equipped standard with a solar panel sunroof to parallel charge the Fe battery. Powered by the Fe battery pack alone, the F3DM can travel over 60km (38+ miles). The extended range HEV mode allows the car to achieve another 500 km (or 313 miles) with a maximum speed of 150km/h (about 93.2 mph).
