At the 2011 Detroit auto show, Honda has revealed what both three- and four-door versions of its ninth-generation Civic offering will look like. Whereas the current eighth generation Civic signalled a leap into the ergonomic unknown with its radical cabin architecture, the Detroit show cars have tidied things up a bit.Exterior styling of the show cars should not change much for road car homologation, the key styling theme being a more aggressive appearance.The four-door gains a more rakish nose, redesigned boot surface and new taillights as its most notable upgrades. LED illumination strips reside in the lower-bumper cut-outs too.Civic’s three-door coupe cues similar styling changes to its four-door sibling, with its larger doors (obviously) and central exhaust the distinguishing features.Improved hybridHonda’s obviously coy concerning the exact technical upgrades for the new Civic range, yet it has said a more sophisticated range of i-Vtec engines will be part of the mix. The improved engine line-up will be buoyed by lithium-ion battery powered hybrid models, signalling a move away from Honda’s slightly antiquated nickel-metal hydride hybrids – as found in the current Insight and CR-Z. Ninth-generation Civic is expected to go on sale globally during the second-half of 2011.
