Challenger’s new engines

Going against the grain of downsizing, Dodge has revealed that the Challenger SRT8 will be getting a bigger Hemi V8 for 2011.



And, just so everyone knows, it’ll be known as the SRT8 392 - a reference to the engine’s capacity in cubic inches, which equates to 6.4 litres.

The new engine boasts 470 bhp (350 kW / 476 PS) and 637 Nm (470 lb/ft) of torque which, compared to the 6.1 litre Hemi that it replaces, is a useful increase of 45 bhp (33 kW / 45 PS) and 67 Nm (50 lb/ft). The newer model will be identifiable by its modified front spoiler and larger splitter, while underneath the suspension has been tweaked to cope with the extra grunt.



To celebrate the new arrival, the first 1,492 SRT8 392s off the line will be Inaugural Edition models which have 20” SRT wheels and ‘392 Hemi’ badges. Colour choice is Bright White Clear Coat with Viper Blue stripes or Deep Water Blue with Stone White stripes, both of which come with a Pearl White leather interior that features blue stitching.



The 2011 Dodge Challenger SRT8 392 is scheduled to arrive in dealers during the fourth quarter of 2010.



It’s not just the Hemi that’s been revised, though. The V6 models are set to get the new Pentastar engine that was first introduced in the 2011 Jeep Grand Cherokee. It’ll also be seen in the Dodge Charger, Avenger, Durango and Journey, as well as the Chrysler Town and Country, 200 and 300.



Using one engine across so many models is all about manufacturing efficiency and cost saving. Incredibly, the Pentastar will eventually replace seven legacy V6 engines, and it’s expected that it’ll be found in a third of all Chrysler Group vehicles built.



Power and torque will be tuned for specific applications, and in the 2011 Challenger it’ll break the 300 bhp barrier. 305 bhp (227 kW / 309 PS) to be exact, which is a big increase versus the 250 bhp (186 kW / 253 PS) that today’s car has. Torque is also up, from 338 Nm (250 lb/ft) to 363 Nm (268 lb/ft).
