[EcoModder.com] actual cd numbers - Fuel Economy, Hypermiling, EcoModding News and ...: I believe coast down testing is the method used by basjoos to determine his Cd, and I think aerohead has used it to gauge impacts also. Not everyone has run it through the spreadsheet as I have, but it is easy to overlay the graphs on top of each other and see that you are coasting longer/faster.

[egmCarTech] 2010 Toyota Prius Review, Comparison and Specs - egmCarTech: This further emphasizes the cheese-wedge-like design, but is tremendous for aerodynamics. While the wheelbase retains its dimensions, the overall length of the car is increased by 0.6 inches, largely in part due to the front cowl being moved forward.

[Auto Show by Auto Trader] 2011 Hyundai Sonata GL « Auto Show by Auto Trader: It reminds me of a person who is always the .In fact, the Sonata not only has the best in-class horsepower (based on a 4-cylinder engine), but it also has the best estimated fuel economy with 9.4L/100km in the city and 5.7L/100km on the highway.

[EcoModder.com] Underbody Flow Simulation Images - Fuel Economy, Hypermiling ...: I guess that would depend on whether the main goal is to reduce lift at racing speeds or to reduce drag and lift at highway speeds. I think in my case a smooth underbody that angles upward to the rear of the car can act as a diffuser to help fill the wake and reduce lift.

[Daily Autos Blog] 2010 Mazda CX-9 Grand Touring AWD Review & Test Drive | Daily ...: The 2010 CX-9 is powered by a 3.7 liter DOHC V6 engine making the most complex pursuits as easy and pleasurable as possible.  The 60-degree short-stroke V6 is state-of-the-art throughout.  Advanced features include a die-cast aluminum block with cast-in iron cylinder liners and aluminum cylinder heads for minimal weight.  The valvetrain includes chain-driven dual overhead camshafts for minimal maintenance, four valves-per cylinder with direct acting bucket-type actuators, and variable intake valve timing.  A high 10.3:1 compression ratio maximizes efficiency and power output while the throttle is electronically controlled for instantaneous response.  Computer-aided-engineering analysis was extensively used to configure the cylinder block casting, to shape intake and exhaust ports, and to design the high-volume exhaust system fitted with three large mufflers.  Very low back pressure is one of the reasons why the power curve is still ascending at the 6,500rpm redline.  Engineering details even extend to a roller-chain- cam-drive sprocket lined with rubber for quiet operation.  A power peak of 173hp at 6,250rpm provides the CX-9 with excellent acceleration and passing performance.  The torque curve keeps 250lb.ft. from 3,000 to 6,000rpm and peaking at 270lb.ft.

[Perrys Motor Sales] Perrys Automotive Blog | 2009 Mazda MX-5 And Mazda MX-5 Roadster Coupe: For 2009, Mazda MX-5 customers will now have a choice of four powertrains, all fine-tuned to use less fuel - the 126ps 1.8i or higher-revving 160ps 2.0i with five-speed gearbox, the 160ps 2.0i with a smoother-shifting six-speed manual gearbox and the new 160ps 2.0i ”˜PowerShift”˜ six-speed sequential paddle-shift transmission with full-auto mode. The engine fine-tuning and aerodynamic drag reductions have resulted in significantly lower CO2 (from 167 g/km for the 1.8i, down from 174 g/km) and enhanced fuel consumption (from 40.4 mpg for the 1.8i, up from 38.7 mpg).

[Barretts Kent] Barretts Kent: The New Citroen C3: Start technology, will see diesel versions emitting as little as 90g/km CO2, to be followed by new generation three-cylinder petrol engines with less than 100g/km CO2. Modern and perfectly at home in the 21st century, the new C3 can be well connected with USB, iPod and Bluetooth® functionality, as well as offering Citroën’s ”˜MyWay’ satellite navigation and Hifi System®.
