Rumors are gathering pace that Toyota is working on a two-door coupe version of its ultra-popular Prius hybrid, possibly scheduled to hit the market sometime in 2012.
The latest reports suggest that the Japanese outfit is currently developing a compact 2+2 Prius-based hybrid sports coupe featuring a beefed-up version of its 1.8-liter 2ZR-FXE four-cylinder engine, capable of achieving around 134 hp – 36 hp more than the sedan counterpart.
Although the higher power levels are likely to affect the Prius’s impressive fuel mileage, insiders are speculating that the company’s Hybrid Synergy Drive system will keep this to a minimum.

The Inspired Economist (IE) recently interviewed GE’s Bob King, a 30-year veteran of the company who has driven the company’s research in the advanced electric and hybrid vehicle space.
With the energy crisis of the late ’70s, GE began to aggressively pursue the development of an electric test vehicle, creating a prototype that included nearly all the components that can be found in today’s hybrid vehicles. Bob worked on this, and also on the development of GE’s hybrid bus in 1996. The bus established the emissions requirements for NYC’s hybrid transit buses and paved the way for those that you see on the roads today.
Bob has witnessed the cyclical nature of the country’s demand for energy-efficient cars and the changes in technology that have resulted in advancing the industry. Here’s what he had to say to IE.
IE: What is GE’s hybrid vehicle? Can you describe it? It’s USP?
BK: GE researchers are working on hybrid systems and battery technologies for a hybrid locomotive and for heavy-duty vehicle applications, which we believe could cascade down and help accelerate key advancements for Plug-in Hybrid Electric Vehicles (PHEVs) in the automotive sector. In fact, we also have been performing some research in conjunction with the lithium-ion battery maker A123Systems to support their battery development for automobile applications.

Imara Corp. has announced a new generation of lithium-ion (li-ion) batteries made specifically for high power devices such as lawnmowers, power tools, hybrid vehicles and even grid storage. The company uses unique materials science technology to provide high-power, high-energy and extended cycle-life batteries and battery packs.

The panels can charge the battery enough for a 3-mile trip in just one hour. After a full charge of 30 hours in the sun, the car can travel up to 90 miles.

Toyota’s yet-to-be-unveiled 2010 Prius will have a bigger engine and a higher top speed, but improvements to CO2 emissions and fuel efficiency will take a backseat.
While the company has plans for a hyper-efficient plug-in version of the Prius by 2011, the standard model will make relatively few upgrades to its environmentally-friendly features. “It will be cleaner, with CO2 emissions below 100gm per kilometer,” said Miguel Fonseca, a Toyota managing director. “We could have gone lower but, instead, we have chosen to give the Prius better performance.”

Recently, I discussed the interaction between clean energy and the future of plug-in hybrid electric vehicles (PHEVs). The study cited makes it clear that unless we clean up power production, there isn’t much point in moving to PHEVs from regular, old hybrids (HEVs).
Interestingly enough, MIT has just come out with a new study, profiled by Green Car Congress, which studies all sorts of vehicle options and how each vehicle will perform in well-to-wheel greenhouse-gas (GHG) emissions. This study was done particularly on HEVs, PHEVs, battery electric vehicles (BEVs), and fuel-cell vehicles (FCVs). The MIT researchers came to the conclusion that ultimately, electric propulsion in automobiles could eliminate our dependence on petroleum, which to me sounds like an exciting prospect, regardless of GHG emissions.
French analysts have concluded that the wild popularity of gasoline-hybrid electric vehicles in the United States could potentially hinder development of more sustainable and advanced green vehicles:
Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France. They suggest that the adoption of HEVs might even slow development of more sustainable fuel-cell powered electric vehicles.
The researchers go on to argue that the “misinformed craze” for hybrids in the U.S. is creating a situation where every manufacturer must include hybrid technology in their portfolio in order to stay afloat:
