This week: new VW Golf R to get 350bhp; shock Aston Martin hypercar is after the P1; radical tech to save diesel; world's best bangers

In this week's issue of Autocar, we uncover the secrets for Volkswagen's hottest Golf yet, the next-generation and 350bhp-wielding R model.

We also reveal Aston Martin's plans for a McLaren P1-rivalling hypercar and look at the Audi E-tron GT, an electric model destined to fight with the Tesla Model S.

Vauxhall's second new GSi model is here in Corsa form, so we give a heads-up as to what powertrain to expect.

Has diesel really had its day? Not if new groundbreaking tech developed here in Britain makes it to market in time. We examine how this technology can drastically cut NOx output.

Also in this issue

We drive the Dallara - the racing car company that's now making road cars - Stradale to see if motorsport tech translates into an engaging and forgiving sports car.

Forgiving is not a word we'd associate with the Ferrari 812 Superfast, which is tested on Britain's rough surface for the first time.

There's a stint in the new Porsche 718 Boxster GTS, while we also have a go in the new Audi A7 Sportback in 50 TDI form. Our full road test is dedicated to the peppy VW Up GTI.

What's the best new electric hatch on sale? We pit three of the market's best – the new Nissan Leaf, VW e-Golf and Renault Zoe – head to head to find out.

Formula 1 is nearly back, so we provide a full preview to the new season - but not before we try to tempt you away from the tellybox to go out and buy a brilliant bargain banger.

Our cars

Autocar's fleet loses a long-standing favourite, the Alfa Romeo Giulia QV, but thankfully the fresh arrival of the Hyundai i30N is keeping us entertained.

The same can be said for the Honda Civic Type R, which enjoyed little rest during the recent snowy weather.

Deals

Do airbags have a best before date? And should you buy a used VW Scirocco? These key motoring questions, and many more, are answered in this week's used section.
