The AMG A45 S of course is the world's hottest. We say hottest, we mean to say powerful, because there will certainly be leaving a trail of fire as it shoots across the streets. All four wheels get power thanks to the 4Matic all-wheel drive system and it's the 8-speed dual clutch transmission that provides the power to them. The A45 features six driving modes - Comfort, Sport, Sport+, Slippery, Individual and Race. It can do a 0-100 kmph run in just 3.9 seconds and that's fast, really fast!
