The Alto K10 is known for its great fuel efficiency, this is one of the Alto K10's biggest strengths. For many buyers, this frugality at the pump is a big factor, especially for those shopping for an economical city runabout. But the K10 is also remembered for its pretty basic feature set for some of its rivals, which come with more modern amenities and tech features. This throws up a debate amongst potential buyers and car enthusiasts as to whether to trade off running costs for creature comforts. A few say it's worth the expense in features and the increase in fuel consumption given the savings over time on fuel, while the others say we pay for certain conveniences and safety features with the price and the increase in fuel consumption.
