Handling Ranked 2018 Audi RS 3 2.5T quattro AWD better.
"The all wheel-drive Audi is second to none when it comes to handling and putting the power and traction down to the asphalt. The smaller, lighter more powerful RS3 just feels a lot more nimble in and out of corners. "
Family Car Ranked 2018 Audi RS 3 2.5T quattro AWD worse.
"The C43 is a full-size sedan. It has a full size trunk and it looks like you could put four adults in the back seat. The RS3 looks like it would be difficult to put two teenagers in the back seat. You can configure the RS3 to have additional truck space, but it is at the cost of the back seat(s). "
Value Ranked 2018 Audi RS 3 2.5T quattro AWD worse.
"The RS3s are a very hot ticket item and the dealerships are having a very hard time keeping up with demand. The cars are selling for MSRP. There are good deals to be had on the C43 with a little negotiations. I believe you will find it much easier and cheaper to find a C43 Mercedes than a RS3. "
Would Buy Ranked 2018 Audi RS 3 2.5T quattro AWD better.
"I really like a car that feels like a go-cart when it comes to handling. The RS3 just feels a lot more nimble and agile than the C43. The C43 is by no means a slouch, it is truly a great car by all means in its own rights. However with that said, I am beginning to think there should be a new class of sedans, that has the RS3 in it all by itself. Its size, weight, performance and all wheel drive literally puts it in a class all by itself. "
