The Audi RS 7 is one of the best cars in the world - and it just got better

The Audi RS7 is one of fastest cars with four doors and a trunk that money can buy. This week, Audi introduced the new RS7 Performance edition loaded with all kinds of go-fast upgrades.

Earlier this year, Business Insider spent a weekend behind the wheel of Audi's road-going rocketship and absolutely loved it. Now there's a new, improved RS 7. We haven't been behind the wheel, but it certainly looks to be even better and faster than before.

When it hits showrooms, the RS7 Performance will be the top-of-the-line offering in Audi's A7-series.

Look for more information on the car during the 2015 LA Auto Show set to run from November 20-29.

Here's a closer look at the new Audi RS 7 Performance.
