Shake, Rattle and Roll – The history of the IQECAG (a.k.a. the Shaker hood)

If you’ll harken back to your middle school science class with me for a second, you’ll remember that in order to make fire, you need three ingredients: fuel, ignition and air – or, more specifically, oxygen. You’ll also remember that cold air is denser than hot air, putting more oxygen in the same amount of volume. While the modern internal combustion engine does a fine job of delivering fuel and ignition, that cold air part becomes tricky as you try to route fresh air from outside through a hot engine compartment.

All About the SRT® Hellcat, Part 4: Superchargers and HEMI® V8 engines; 1 + 1 = 3

As we marvel at the Dodge SRT® Hellcat HEMI® engine’s status as the world’s most potent regular production V8 offering*, we’re reminded that the history of the automobile has seen the appearance of a nearly countless multitude of engine configurations. Since the dawn of the worldwide auto industry, the liquid cooled, reciprocating, internal combustion engine has been rendered in more distinct configurations than there are breeds of cats, of which there are 39.  
 
Looking back over the past 115 years, car buyers have been offered piston engines with 1, 2, 3, 4, 5, 6, 8, 10, 12 and even…

All About the SRT® Hellcat, Part 2: A Look at the Challenger SRT® Hellcat’s Airflow Management System

Scoops Don’t Always Scoop …
 
When you sell a car capable of 199 mph, you need to make sure the body makes efficient use of airflow management. After all, as one anonymous engineer once proclaimed: “Cars make pretty lousy airplanes above 150 mph.” 
 
In the case of the 2015 Challenger SRT Hellcat (and its sibling the Charger SRT Hellcat), many hours were spent in the wind tunnel to make sure each platform remained stable at terminal velocity. 
 
Chin and trunk spoilers were fine-tuned, under-car belly pans massaged and fascias reconfigured to slip through the air stream without excess drag or lift. 
 
But what…
