The latest from Maruti Suzuki is a new 3rd generation Wagon R. It moves to a larger platform for the first time - and as a result is now an India specific Wagon R too. It also adds a larger 1.2 litre engine to the existing 1.0. Both engines have an AMT option. We test the manual and automatic in this comprehensive review. And also introduce you to Maruti's new Smartplay Studio touchscreen interface that debuts on this car.
