Next-Generation Chevrolet Volt Features All-New Voltec Powertrain

Added by admin 30/10/14

When the next-generation Chevrolet Volt debuts at the North American International Auto Show in January, it will feature an all-new Voltec extended range electric vehicle (EREV) propulsion system substantially developed from Volt owners including data collected on their driving behaviors.
The Voltec system includes the battery, drive unit, range-extending engine and power electronics. The new system will be more efficient and offer greater EV range and fuel economy compared to the current generation.
"Our Volt owners truly love the EV driving experience, with more than 80 percent of all trips being completed without using any gasoline. We've used their real-world experiences to define the next generation Chevrolet Volt," said Alan Batey, head of global Chevrolet. "By putting our Volt owners at the center of what we do and leveraging our electrification engineering leadership, we've been able to raise the bar and will exceed their expectations with the new Volt."

Enhanced Battery System Capability

General Motors' industry-leading battery technology has been improved for the next-generation Volt. Revised cell chemistry, developed in conjunction with LG Chem, increases storage capacity by 20 percent on a volume basis when compared to the original cell, while the number of cells decreases from 288 to 192. The cells are positioned lower in the pack for improved (lower) center of gravity and the overall mass of the pack has decreased by almost 30 pounds (13 kg).
Approximately 20 million battery cells have been produced for the more than 69,000 Chevrolet Volts on the road today with industry-leading quality levels of less than two problems per million cells produced.
The battery system continues to use the Volt's industry-leading active thermal control system that maintains electric range over the Volt's life.
"The current generation Volt's battery has proven to provide our owners exceptional performance when it comes to quality and reliability," said Larry Nitz, executive director of GM Powertrain's electrification engineering team.
Based on a GM study of more than 300 model year 2011 and 2012 Volts in service in California for more than 30 months, many owners are exceeding the EPA-rated label of 35 miles of EV range per full charge, with about 15 percent surpassing 40 miles of range. Current generation Volt owners have accumulated more than 600 million EV miles.
"It would have been simple for us to tweak our existing battery to provide nominally increased range, but that's not what our customers want," said Nitz. "So our team created a new battery system that will exceed the performance expectations of most of our owners."
EV range estimates will be revealed in January at the North American International Auto Show in Detroit.
GM will manufacture the Volt battery pack at its battery assembly plant in Brownstown, Mich.

Toyota Hybrids hit Seven Million Sales

Added by admin 18/10/14

Toyota has posted an impressive global milestone with confirmation it has sold its seven-millionth hybrid vehicle.
Firmly established as the world's largest producer of hybrid vehicles, the tally includes 3.3 million sold in Japan, 2.5 million in the United States, 770,000 in Europe and more than 67,000 in Australia.
The latest one-million sales were achieved in record time - just nine months after Toyota (including Lexus) reached the six-million hybrid threshold in December last year, which doubled the three million total passed in February 2011. Globally, Prius accounts for almost half the overall total with 3.36 million sales - making it easily the world's best-selling hybrid vehicle.
In Australia, the locally built Camry accounts for more than half the 55,442 hybrids sold by Toyota dealers, followed by Prius with almost 19,000 sales. Local Lexus dealers have sold 12,244 hybrids, led by the CT 200h and the RX 450h.
TMC estimates its hybrid vehicles have cut carbon-dioxide emissions by approximately 49 million tonnes* and saved approximately 18 million kilolitres* of fuel compared with vehicles of similar size and driving performance using petrol-only engines.
Toyota began selling the Prius in the Japan in 1997 and in Australia in 2001. Camry Hybrid has been built and sold in Australia since 2010 while the Prius was expanded into a family of three vehicles in 2012 with the addition of the Prius c city car and the Prius v seven-seater.
Over the 17 years since the first Prius was launched, Toyota has endeavoured to encourage the mass-market adoption of hybrid vehicles, which use less fuel and emit fewer tailpipe emissions than equivalent petrol-only models. Toyota has positioned hybrid and its related developments as core technologies for the 21st century. The company therefore plans to continue working to enhance performance, reduce costs and expand its product line-up to create vehicles that are popular with consumers.

Lamborghini goes plug-in hybrid with 910-hp Asterion concept

Added by admin 02/10/14

Lamborghini has long been on the cutting edge of auto technology in terms of potent powertrains and lightweight materials. However, its colleagues over at McLaren and Ferrari have it beat when it comes to electrification, each having introduced a hybrid flagship at last year's Geneva Motor Show. In Paris, Lamborghini officially surpassed those marques, presenting its very first hybrid, a 910-hp plug-in with more than 30 miles (50 km) of all-electric driving range.
Lamborghini's Asterion LPI 910-4 offers power on par with the LeFerrari (we still cringe at referencing that model name) and McLaren P1, but its plug-in hybrid drive provides a respectable all-electric range of 31 miles (50 km). That range is more on par with the 38-mile (61-km) Chevy Volt than it is with the 6.2-mile (10-km) P1 (the LeFerrari doesn't have a full-electric mode).
For those well-versed in Lamborghini nomenclature, the "I" inside the familiar "Longitudinale Posteriore" HP-4WD format stands out like a sore thumb. It stands for "ibrido," Italian for hybrid, and as Lamborghini's first hybrid, it's the first model to need the I.
