Many modern cars use small turbocharged engines rather than larger non-turbocharged alternatives, and although the engine capacity might seem insufficient, in truth the turbocharger more than makes up for the smaller cylinders. The Octavia Estate with the 110PS engine isn't the quickest - 0-62mph takes around 10 seconds, but unless you plan to drive flat out on the motorway all the time you should find this engine is more than adequate. Alternatively you could take a step up to the 1.5 TSI version, which offers 150PS. If in doubt, take a test drive including some motorway miles to put your mind at rest.
