Nissan Leaf

Nissan Leaf is Something to Get Excited About

1 Comment

Nissan Leaf
Simple, stylish and on your show room floors this year, the Nissan leaf is something to watch for in the near future.  In the midst of painstaking delays, vaporware, and just face palming prototypes,  the Nissan Leaf is a breath of fresh air.  Their platform is simple, 100 miles per charge, good electric acceleration, and actually going into production at an affordable price ($25K-$35K).  The Nissan Leaf will be available to US buyers in Fall 2010.  More companies should be this forthright.

Perhaps their gall partially comes from the American Recovery and Reinvestment Act that granted the EV Project nearly 100 million dollars to deploy the Nissan Leaf and 11,210 fast charging stations in the US.  Here are the details on the specific Nissan Leaf hot spots from the EV Project site:

In the summer of 2010, charging infrastructure will be deployed in the following major population areas: Phoenix (AZ), Tucson (AZ), San Diego (CA), Portland (OR), Eugene (OR), Corvallis (OR), Seattle (WA), Nashville (TN), Knoxville (TN) and Chattanooga (TN). The Nissan LEAF will be available in those same areas in the fall of 2010 to consumers and fleets.

In February 2010, Nissan announced that 50,000 people in the US had already registered to have first priority.  Time magazine even called the Nissan Leaf one of the 50 best inventions of 2009.  America is ready for a change in transportation.

This is all very similar to the EV-1 project of nearly 15 years ago.  Except with our domestic brands struggling and failing to get the hint that they need to innovate, a Japanese car manufacturer is partnering with our most advanced infrastructure projects.  I for one welcome our new Japanese automotive overlords.

China: BYD to Sell Electric Car This Month

F3DM
According to the Chinese automobile manufacturer, the F3DM will be available for private purchase in Shenzhen on March 29th, 2010.

The F3DM is a range extended electric vehicle, meaning it has a completely electric drivetrain and a gasoline engine is only incorporated as a generator to charge the battery.  BYD claims their Dual Mode is different from a range extended electric vehicle because it actually has three modes of operation: 1) Full battery-powered electric mode 2) Series-hybrid mode, in which an engine drives a generator to recharge the batteries, acting as a range-extender like in the Chevy Volt. 3) Parallel hybrid mode, in which the engine and motor both provide propulsive power, like in the Toyota Prius.

The BYD F3DM is priced at $22,000 and will hopefully be available in the US by 2011.  However, this is twice the price of an equivalent car in China using traditional fuel.

A BYD spokesman said that the new version of the F3DM, available for private buyers will implement more advanced battery and electronics to further enhance efficiency.  The first selling location will be Shenzhen, which plans to have 24,000 cars on the road, possibly with the help of government subsidy programs.

Volvo Recharge

The Volvo Recharge

Volvo Recharge
On the outside, the Volvo Recharge is simply a Volvo C30 compact hatchback.  But the inner workings of this fascinating concept are what make this car truly exceptional.  The Recharge is a series hybrid that uses cutting edge drive train (or lack thereof) technology that allows each wheel to be powered by individual electric motors, seen in such drivable concepts as the Venturi Volage and  Eliica. This eliminates the need for bulky transmissions, a large central motor, and axles.  So not only will this create less power loss and decreased weight, but you will have more room for cabin space and storage.

This plug-in hybrid has about a 60 mile range before a 1.6 liter diesel engine kicks in to generate more electricity.  This is all on about a 3 hour charge.  Therefore, most daily drivers will never need a drop of diesel.  When the combustion engine is aiding the motors, the fuel efficiency is stated to be in the 40 mpg range.  The car gets from 0-60 in 9 seconds, which won’t win any stop light drag races, but is sufficient for a commuter car.  The Recharge has a top speed of about 100 miles per hour.

Here’s a view of the Volvo Recharge’s internals:

Volvo Press Release

Volvo Car Corporation launches unique cooperation for the development of plug-in hybrid cars in Sweden

Together with electricity provider Vattenfall, Saab Automobile, ETC and the Swedish state, Volvo Car Corporation is launching a joint broad-based research venture to develop spearhead technology in the area of plug-in hybrid cars. Sweden will be the arena for the field tests.

“I see this project as a positive further development of sustainable personal transport. We have a unique opportunity to take the lead when it comes to innovations for advanced green-car technology”, says Fredrik Arp, President and CEO of Volvo Car Corporation.

The aim of the project, which is being carried out jointly by Volvo Car Corporation, Saab Automobile, Vattenfall and ETC, is to develop and demonstrate the next-generation hybrid cars. A fleet of 10 plug-in hybrids will be produced that can be recharged directly from the mains wall socket.

Volvo has long experience of cooperation with a variety of society’s actors and with this project the company aims to participate in and shape decisions and initiatives that are taken both within and outside the car industry.

“We want to be involved in setting up the rules for the future and to help build up broad-based competence in Sweden in this vital area,” says Fredrik Arp.

Over a five-year period, Volvo will invest just over 11 billion SEK in development aimed at reducing fuel consumption and emissions. Volvo already offers its customers one of the industry’s widest ranges of Flexifuel engines. In parallel the company is continuing to enhance the efficiency of its petrol- and diesel-powered cars. 2008 will see the launch of car models that release less than 120 grams of carbon dioxide per kilometre.

Volvo is also focusing intensively on hybrid technology. In the medium term the company will introduce hybrid variants where an electric motor supports the combustion engine. In the longer term, plug-in hybrids will be introduced. One example of this was presented in autumn 2007 with the Volvo C30 ReCharge Concept. Used in the most effective way, this concept car cuts emissions of carbon dioxide by about 65 percent compared with the hybrid cars available on the market today. And if the electricity comes from CO2-sustainable sources such as hydropower and windpower, this figure improves still further.

Electric Car Sound Debate

Leave a comment



For 30 years, engineers have been working on making cars quiet, so the criticism that electric cars are, in fact, too quiet, seem foolish. And in my humble opinion, it is completely ridiculous, kind of like this article I just read about a UK politician’s idea to put cowbells on electric cars to make them more safe.

Most modern, four cylinder vehicles are virtually inaudible at low speeds. And at constant speeds of 30-60 mph, the most audible noise of a modern sedan is the tires rolling against the pavement and wind resistance.  Granted, at idle and extremely low speeds, an electric vehicle is basically silent compared to an internal combustion engine.  However, you cannot even notice the discrepancy unless you are within five feet of the car to begin with.

Anyway, take a listen to the Fisker Karma in action and tell me that the electric vehicle doesn’t make any noise:

Pretty similar to a jet engine spooling up. This is a perfectly acceptable amount of sound. The whole premise of a car being “too quiet” is ridiculous. Electric cars are inaudible because they are efficient. Less heat, friction, moving parts, and noise means less energy is wasted turning the wheels.

2010 Tesla Roadster Sport

Leave a comment



This is a pretty cool video on the Tesla Roadster Sport.

First, there is a pretty informative overview of the interior. The Roadster now has a working glove compartment, alright! The transmission selector is now four buttons on the center console instead of a traditional lever. You can select from drive, neutral, reverse, and park. The console also features a port for your ipod or iphone, which from experience, really comes in handy nowadays. Accents on the car are all true carbon fiber, which is rare, because of how commonly it is faked.
Tesla Roadster Sport

The host also gives the battery of the Tesla Roadster Sport a once over. Giving the predictable, “There’s not much to look at here” quip. The Tesla Sport only has a single speed, so there is no complicated transmission bungling up the power to the wheels. He notes the car has 288 hp as apposed to the 248 of its predecessor; which gives it a 3.7 0-60 acceleration, .2 second quicker.

The best part of this video in my opinion is the host’s explanation of the Roadster’s regenerative brakes. When you hit the brakes, you are still using friction braking. The regenerative braking is when you lift off the gas, and you are slowed down by the regen brakes to give a “synthetic compression braking”. So it gives you that pulled forward feeling like you get when you lift off the gas in too low a gear in a regular vehicle.
