DaimlerChrysler's Heavy Duty Engine Platform (HDEP), its delayed global platform will launch in the US in August, Freightliner sources tell us. We do not know whether the entire 12, 14 and 15 litre range will be launched at once, but have been made aware of significant problems with the higher volume engine. Freightliner's new Class 8 truck, due for launch in May will be the first recipient of the new engine, which replaces the now venerable Detroit Diesel Series 60 in most markets.

It's uncertain as to whether a European HDEP will break cover at the European RAI Show, or an Asian variant at the Tokyo Truck Show, both taking place in October. However, HDEP is a key plank in DC's global policy, an so we assume that global availability is not far away.
