Saturn Aura Green Line
The Saturn Aura Green Line starts at $22,695 including destination charge

General Motors has officially announced pricing for its 2007 Saturn Aura Green Line hybrid sedan. The vehicle will retail for $22,695 including destination charge and will also be eligible for a $1,300 tax credit from the federal government for 2007 tax returns.

For comparison, the Honda Civic Hybrid, Nissan Altima Hybrid, Toyota Prius and Toyota Camry Hybrid are priced from $22,985, $25,015, $22,975 and $26,820 respectively, including destination charge.

The 2007 Aura Green Line is considered to be a "mild hybrid" since it cannot move forward under electric power alone. The Aura Green Line hybrid powertrain (164HP 2.4 liter 4-cylinder plus electric motor/generator) is capable of providing mild electric assistance under acceleration, stopping the engine when the vehicle comes to a stop and starting it back up again when the gas is pressed. The car also takes advantage of regenerative braking to help recharge the battery pack.

The Aura Green Line boasts EPA ratings of 28MPG/35MPG city/highway compared to 20/30 for an Aura with the 224HP 3.5 liter V6 and 20/28 for the Aura with the 252HP 3.6 liter V6.

A more viable comparison may be with the Pontiac G6 base sedan. This vehicle is the Saturn Aura's platform-mate and also uses the 2.4 liter 4-cylinder engine and transmission without the hybrid add-ons. EPA ratings for the G6 are 23/33 city/highway which means that the Aura Green Line’s hybrid system affords the driver an additional 5MPG in the city and 2MPG on the highway.

RE: Hybrids Can't Touch This!

Of course, the real question to ask here is why aren't more companies making hybrids with diesel engines?!

There's absolutely nothing about the basic concept of a hybrid that limits it to a gasoline engine. However PSA is the only company I know of that is actively working on a diesel-electric hybrid. They have a Peugeot 307cc Hybrid concept car that is rated for 4.1L/100km (slightly better then the Prius' 4.3L/100km) and a smaller engined Citroen C4 Hybrid concept that manages 3.4L/100km.

Of course, the downside with diesel is air pollution. While they use less fuel, the fuel they do burn is dirtier with more particulate emissions. In Europe regulations tend to focus much more on greenhouse gas emissions, where diesels are better. However in North America we focus more on air pollution and smog causing emissions, and here diesels tend to struggle. Newer diesels (and the new diesel fuel regulations) have improved though, and a well designed hybrid with a CVT transmission should be better still since a lot of the air pollution comes from running the engine outside of it's 'ideal' rev range.
