Renault’s not only giving its diminutive Modus MPV a facelift, but it’s also creating a new, bigger version, the Grand Modus, both of which go on sale in 2008.The Grand Modus sits on an extended wheelbase that’s a whole 93mm longer than the standard car’s. That makes for improved boot space and/or rear passenger room; as in the normal Modus, the rear seat can be slid forwards or backwards to maximise luggage or passenger space.Boot space in the Grand Modus is from 305 to 410 litres, compared with 217 to 293 litres in the Modus.From the outside, the best way to spot the Grand Modus is the larger rear quarter-lights. As for spotting the ingeniously named New Modus from its predecessor, you’ll have to be seriously attentive. Changes include subtly reworked front and rear ends, and not a whole lot more. Just enough, we’d say, to keep it a la Modus.
