Economy, what's that? New Viper to get 8.7-litre V10

Down sizing be damned! Chrysler's gigantically nosed Viper flagship is set to get an 8.7-litre V10 when the new model is launched in autumn 2012.

Based on the current 8.4-litre engine, the new 8.7-litre unit won't be the last word in economy (ok, so its economy isn't exactly stellar at the moment) but expect over 600bhp and 560lb ft of torque on tap for burning all that fuel.
