Annual Fuel Cost: $1,018
Air Pollution Score: 9

UCS Hybrid Value: High

ACEEE Green Score: 50

• Most affordable hybrid car available.

• Capable of significantly better mpg than the EPA’s estimates with a little effort.
• Has a decent amount of zip; transitions between gas power, electric power and gasoline-electric are super smooth.
• If you don’t regularly need much room for multiple passengers (the back seat is really tight), the Insight may be your best option among hybrids because of its price.

2010 Toyota Prius

EPA City/Hwy MPG: 51/48
Annual Fuel Cost: $855
Air Pollution Score: 8

• Capable of electric-only mode at low speeds (up to about 25 mph) and highway coasting.
• Optional solar roof powers a fan that helps cool the interior when parked in hot weather.
• Named best new-car value by Consumer Reports for its reliability and low cost to operate.
• Comfortable interior, with room for five. Solid safety ratings and features (but do ask about the specific car’s brake recall status when you’re Prius shopping).

2010 Volkswagen Golf TDI

Type: Diesel, hatchback
Price Range: $23,104 – $24,809
EPA City/Hwy MPG: 30/42
Annual Fuel Cost: $1,324
Air Pollution Score: 6
Greenhouse Gas Score: 8
ACEEE Green Score: 43

• The best small diesel car for your buck.
• Eligible for a federal tax credit of up to $1,700.
• Sporty drive and looks, but still capable of mpg in the upper 30s or low 40s.
• With 40-plus mpg at highway speeds, the Golf is a great option for primarily highway drivers.
• If maintained, diesel engines typically hold up longer (with better mpg, too) than gas engines.
• May require slightly more ongoing maintenance (which might be covered in the buyer’s package, depending on current offers) than a comparable gas car.

2010 Volkswagen Jetta TDI

Type: Diesel, sedan
Price Range: $23,580 – $24,680
EPA City/Hwy MPG: 30/42
Annual Fuel Cost: $1,324
Air Pollution Score: 6

• One of the best examples of how clean diesel technology makes diesel cars a competitive green alternative to hybrid cars.
• Eligible for a federal tax credit of up to $1,300.
• A roomy, comfortable sedan. Wagon version also available for more cargo space.
• Great option for primarily highway drivers and/or those with small families.
• Capable of better mpg than the EPA estimates with a little effort.
• More affordable than the Prius, with comparable real-world highway mpg (low to high 40s).
• Long-term reliability projections are good, but the clean diesel system may require a bit more ongoing maintenance than you’d need for a comparable gas car. Warranties and buyer packages may cover some of that maintenance.
