Thank The RS 5 For That"},"content":{"rendered":"

The new RS 5<\/a>, which is what Audi is now calling the RS 4\u2019s successor thanks to a naming reshuffle where odd numbers mean combustion and even numbers mean electric, was revealed this week. And while the spec sheet reads like the kind of thing that should have RS fans salivating, there\u2019s a problem. A 580-kilogram problem, to be specific.<\/p>

The headline number is 470kW. That\u2019s what you get when you bolt a 130kW electric motor onto the familiar 2.9-litre twin-turbo V6, stuff a 25.9kWh battery pack under the boot floor, and call it Audi Sport\u2019s first plug-in hybrid. It\u2019ll do 0-100km\/h in 3.6 seconds and offers up to 87 kilometres of electric-only range. On paper, it\u2019s an absolute weapon.<\/p>

But here\u2019s the thing. The RS 5 Avant weighs 2,370kg. The B9 RS 4 Avant<\/a>? Around 1,790kg. That\u2019s more than half a tonne of difference. You could literally fill the B9\u2019s boot with sand and still come in lighter than the new car rolling off the line empty.<\/p>

And that gap tells you everything about what\u2019s been lost in the transition.<\/p>
