The Trezia offers 429 liters of boot space, which can be extended if the rear bench is folded (60/40). With all seats in place, the car can accommodate five passengers plus “three large suitcases” (Subaru's claim). Buyers have a choice of two engines, none of which being a boxer - a 1.3-liter petrol and a 1.4-liter diesel unit. Both are sourced from Toyota and offer 99 and 90 horsepower respectively.
