Top Green Car Buying Guide 2007
The American Council for an Energy-Efficient Economy [ACEEE] announces
each year the 12 "greenest cars," based on:
- Tailpipe emissions
- Gas mileage
- Curb weight
1. Honda Civic GX
The Civic GX runs on compressed natural gas with fuel efficiency
of 30mpg [city] and 34mpg [highway]. EPA emissions are the lowest
of all vehicles on the road; being certified as an advanced technology
partial zero emissions vehicle [AT-PZEV] and an inherently low emissions
vehicle [ILEV]. This means the Civic GX conforms to standards for
zero evaporative emissions.
2. Toyota Prius
Toyota's hybrid Prius has a sophisticated parallel hybrid power
system and excellent gas mileage. It is rated as an advanced technology
partial zero emissions vehicle [AT-PZEV], running on either its
500-volt battery pack or 1.5-liter gasoline engine. EPA claims fuel
efficiency at 60mpg.
3. Honda Civic Hybrid
Honda's Civic Hybrid uses Integrated Motor Assist hybrid system
[electric motor integrated with the engine]. Unlike the Prius, which
runs in electric-only mode. The motor is powered by a battery pack
and assists the gasoline engine to achieve improved fuel economy.
4. Nissan Altima Hybrid
Nissan competes with the Toyota Camry using Toyota's Hybrid Synergy
Drive. The Altima Hybrid has a two-mode gasoline-electric drivetrain
that enables it to run solely on battery power when engine demand
5. Toyota Yaris
To minimize emissions and maximize fuel efficiency. The Yaris
relies on high-tech hybrid engine technology - a small 1.5-liter
four-cylinder engine with Toyota's VVT-I intelligent variable-valve
timing and electronic throttle control.
6. Toyota Corolla
The Corolla relies on a variable-valve-timed, ultra-efficient
four-cylinder engine [like the Yaris], to provide is an average
7. Toyota Camry Hybrid
The 2007 Toyota Camry Hybrid unites green technology with luxury.
Its economical hybrid propulsion system is combined with Toyota's
Hybrid Synergy Drive series parallel hybrid system, enabling the
car to operate on electricity, gasoline, or a mixture of both. [Similar
to Prius technology]
8. Honda Fit
This Honda Fit is not designed for power, using only a 109-horsepower,
1.5-liter, VTEC four-cylinder engine. It is designed however, as
an ideal city commuter vehicle. It fits a lot of room into a small
body, making it one of the most compact, green vehicles on the road.
9. Kia Rio5
Another compact vehicle, the Kia Rio5 wagon is driven by a 1.6-liter
four-cylinder engine using continuously variable valve timing [CVVT]
to modify intake and outlet. The 5-speed manual is more economical
than the 4-speed automatic transmission. The EPA estimates 32mpg
in the city and 35mpg on the freeway [manual version].
10. Hyundai Accent
The 1.6-liter Hyundai Accent hatchback is certified as an Ultra
Low Emission Vehicle [ULEV]. The EPA estimates a maximum fuel economy
of 37 mpg on the highway.
11. Hyundai Elantra
The Elantra beats the Accent in terms of emissions; rated as a
partial zero-emissions vehicle [PZEV]. However, its larger, two-liter
engine is not as economical - 28mpg city and 36 highway. Still,
an economical midsized sedan.
12. Honda Civic
The Honda Civic sports neither a hybrid- or gas-powered engine,
but its 1.8-liter four-cylinder engine with Honda's next-generation
iVTEC variable-valve timing technology places it firmly on the top
12 list, even if it is on bottom slot.
