This is part of the problem I have with the new EuroNCAP regs.
The Alto is fundamentally a safe vehicle and as Suzuki have stated, it is about average in its class. The only reason it scores so low is that its "electronic" safety, such as ESP is lacking. This is a budget car for heavens sake, it is built to a price and all these things add cost.
Don't get me wrong, a vehicle should be safe regardless of cost, but passive safety on this vehicle is good.
All the three star rating, as a headline figure, will do is deter buyers, and may be buyers that should be trading out of older less safe vehicles.
It's all about the twisties....
