Is there anything interesting about its design?
Holden has performed cosmetic surgery to bring them closer together, but they still look like distant cousins at best.
Let's focus on the hatch first. This seventh-generation car looks damn good, but it's near impossible to identify the different levels. The easiest way is to look at the wheels (design and size), while the RS has shiny metal blades on the grille, and the RS-V gets that, plus the same trim around the windows for a posher look.
The cabin is also good looking, but regardless of grade, doesn't have the premium feeling the car's exterior looks suggest. Don't get me wrong, the RS-V's interior is cool and stylish, but the use of glossy plastics and a lack of contrasting colour cheapens the vibe.
All Astra hatches have the same dimensions - 4386mm long, 1807mm wide and a height of 1485mm, which is a smidge longer than the Corolla and a bit shorter than the Mazda3. The RS-V auto is the heaviest at 1363kg.
Now the sedan. Holden has styled the front to look more like the hatch but I don't think it's fooling anybody.
The sedan's cabin is also different to the hatch's. We're talking completely different, from the steering wheel to the temperature controls. I'm more of a fan of the hatch's interior styling than the sedan's relatively basic look.
The sedan is 30cm longer than the hatch at 4665mm end-to-end, it's shorter in height though, standing 1457mm tall (-28mm), but is exactly the same width at 1807mm across.
