This week on CNB Bazaar Buzz we first take a look at the diesel A4. There are no changes to the car but that diesel engine is a refined one. The diesel also makes the A4 line-up in India a bit more comprehensive and complete but it's taken a long time for Audi to launch it in India and we find out if it is worth the wait. We then take you back in time to the 21 Gun Salute Vintage Car Rally which showcased over 100 vintage cars and it was an enthralling experience to say the least. Post which, there's a treat for those travel hungry people as we go off the beaten track with Mahindra on its Great Escape to Rajasthan. It's both a break from working behind the desk and an experience of a lifetime. And finally, NDTV's Head of Auto Programming, Siddharth Vinayak Patankar, answers all your queries related to the everything auto which helps you make an informed choice.
