Testing included 11 million customer equivalent miles, with stronger durability testing than any previous Chrysler engine. The 7 year/70,000-mile powertrain warranty is backed by 11 million customer equivalent miles (CEMs) of testing, including more than 200,000 CEMs of durability testing for the average consumer - more than any other Chrysler engine. The battery of reliability tests closely represents real-world driving conditions, in some cases exposing the engine to more severe abuses than drivers can dish out. For example, during a 260-hour period, the 5.7-liter HEMI was repeatedly heated to 240°F and then slammed with coolant that was -25°F.
"The engine was exposed to some of the harshest testing conditions and abuses imaginable," said Donald Dees, Vice President of Quality for the Chrysler Group (and formerly of Toyota, so you know that means something).
