Seat is debuting the 2011 model year versions of its Exeo sedan and ST estate at this week's Paris Auto Show. The VW Group owned company says that both models, which are based on the previous generation Audi A4, are roomier, as there is more space available to backseat passengers after redesigning the front seats and rear bench, while other updates include the introduction of a 7-speed Multitronic transmission on the 2.0 TDI CR Diesel version.
