Toyota Sells One-Millionth Prius Hybrid in the States

Toyota Prius Seen On www.coolpicturegallery.us
The Toyota Prius, a car that is often credited for bringing hybrid-electric technology to the masses, has managed to rack up its one-millionth sale in the USA. The announcement comes shortly after Toyota achieved two more milestones that started with global Prius sales topping the two million mark in October 2010 and overall global Toyota hybrid sales passing three million last month.

“Since the Prius went on sale eleven years ago not a year has gone by when it hasn’t been the number one selling hybrid vehicle in the U.S,” said Bob Carter, Toyota Division group vice president and general manager.

“Prius has become synonymous with the word hybrid and as we see fuel prices starting to rise again, it has accounted for more than 60 percent of hybrid passenger car sales so far this year. Prius paved the way for hybrids and while it is still the hybrid leader in sales and fuel economy, I’m proud to say that since its introduction, 13 other auto brands have seen the benefits of hybrid technology and joined the hybrid market,” Carter concluded.

The first generation of the Prius was introduced in 1997 first in Japan and later on in the U.S. and other countries. The second generation came to fruition in 2003 and remained in production until 2009 when Toyota revealed the current, third iteration of its popular hybrid model.

Toyota claims that since its launch in the U.S. in 2000, the Prius has “saved American consumers more than an estimated 881 million gallons of gas, $2.19 billion in fuel costs, and 12.4 million tons of CO2 emissions” when compared to the average car.

At the Detroit Auto Show in January, Toyota introduced a new member to the Prius family, the Prius v minivan that will go on sale in the third quarter of the year. The company also plans to launch two more models in early 2012, the Prius c compact hybrid vehicle and the Prius Plug-in Hybrid vehicle.

Prime Minister Putin gets behind the Wheel of Russia's First Hybrid Car


When he's not driving a Renault Formula 1 car or a locally-made Chrysler Sebring, Russian prime minister Vladimir Putin test drives hybrid cars – or at least that's what he did on April 1 (no, really), when he got behind the wheel of the country’s first hybrid vehicle, the Yo-Mobile. Built by Yo-Auto, a joint-venture between truck maker Yarovit Motors and Onexim Group, the company of Russian billionaire Mikhail Prokhorov who also owns the New Jersey Nets, the car has an unusual hybrid setup. It uses a rotary vane engine (see video below) that works on petrol and natural gas and is linked to a pair of electric motors.
Instead of a classic battery-pack, the Yo-Mobile uses a super-capacitor, which is an energy-storing device seen by Russian engineers as an alternative to lithium-ion batteries. The capacitor stores the energy produced by the engine and sends it to the electric motors that drive the car. The main advantage of the capacitor is that it doesn't require re-charging from a power network.
The Russian hybrid returns an average fuel consumption of 3.5 liters/100 km (67.2 mpg) and has a combined driving range of 1,100 km (683.5 miles). It accelerates from 0 to 100 km/h (62mph) in 7-8 seconds and can reach a top speed of 130 km/h (80.8 mph).
Set to be built in three different body styles (hatchbach, cross-coupe and a van) from the second half of 2012, the Russian hybrid will retail for $12,000 - $15,000 (€8,500 - €10,500). The most expensive model will have four-wheel drive, satellite navigation system, cruise-control and climate control.
Before getting behind the wheel of the hybrid cross-coupe to drive it to president Medvedev's residence, Putin said to Prokhorov: "I hope your Yo-Mobile will not fall apart on the way." Luckily for the Russian billionaire, it didn't. Scroll down to see Putin's ride

Buick LaCrosse with eAssist Promises 37 Mpg on the Highway

Buick LaCrosse Seen On www.coolpicturegallery.us
Starting this summer, Buick will offer the 4-cylinder LaCrosse sedan with the eAssist micro-hybrid technology as standard. The LaCrosse eAssist uses a variety of systems and body modifications to deliver an estimated fuel economy rating of 37 mpg on the highway and 25 mpg in the city (pending EPA certification).

Mated to a 182HP 2.4-liter Ecotec direct injection 4-cylinder engine and a six-speed automatic transmission, the eAssist system consists of a 115V lithium-ion battery and a 15kW electric motor/generator that enable regenerative braking each time the throttle pedal is released. The electricity produced powers all the electrical systems of the car in order to save fuel.
The eAssist also uses power stored in the battery to provide up to 15HP of electric power assistance in various driving scenarios. “The additional 15 hp provided by electric assist allowed us to lower LaCrosse’s gear ratio without sacrificing reserve acceleration and performance,” said Steve Poulos, global chief engineer of the eAssist system.
“For example, when climbing the grade of an overpass, a normal vehicle will downshift and lose some fuel efficiency, but LaCrosse with eAssist maintains gear for improved performance and increased efficiency,” Poulos added.
Another function of the eAssist system is the engine shut-off mode, which improves fuel economy by cutting fuel delivery in certain deceleration conditions. Other than the mechanical aspects, the LaCrosse with eAssist comes with improved underbody aerodynamics, low-resistance tyres and electronically controlled shutters in the lower grille that close at higher speeds to push more air over the car, thus increasing aerodynamic efficiency.
In order to motivate eco-driving, the car's instrument panel features an Eco gauge that shows the driver how to attain maximum efficiency. The eAssist system will also be available on the Buick Regal in late 2011. Check out the video below to get a better understanding of how the system works.
