Jethro takes the Jaguar XKR-S and the Mercedes SL63 AMG for a spin on the Bedford track for our next installment of Evo. The two performance convertibles make more than 1,000hp so this should be fun to watch.

Powered by a 530hp 5.5-liter biturbo V8 engine, the SL 63 AMG does not feel quite at home on the racetrack. Its enormous amount of torque (590 lb-ft or 800 Nm) spins the rear wheels out of traction when throttle is applied, making neat, tidy laps a hard thing to accomplish.

On the other hand, the Jaguar XKR-S feels completely different from the SL 63 AMG, as it has more body roll and struggles even more with traction. Powered by a 550hp 5.0-liter supercharged V8 engine that produces 501 lb-ft (680Nm), the Jag loves oversteering at all times and feels heavier under braking than the Mercedes.

Jaguar‘s new F-Type Coupe is gorgeous, easily the best looking car on sale right now. There has been a flurry of activity recently, from when we announced the launch to a video roundup just a few days ago, there is a lot of excitment for this R model. The reviews have been coming steadily and everybody is impressed by the package as a whole. Perhaps the most important review for us hooligans is the one by Chris Harris. His verdict in the video above, as per usual is full of drifting, tire smoke and general, English shenanigans. You know, the sort of things that Chris Harris from Drive excels at.

Actually, relative to Harris' other reviews, this one is rather serious. There's a good recap of the F-Type on the road, with Harris referencing the car's "great bottom" and "amazing ass," quite frequently. Surprisingly, Harris says the more powerful F-Type R is just "incrementally" faster than the 495-horsepower F-Type V8 S Convertible. Overall, aside from some minor quibbles, Harris has nothing but praise for the newest cat.

We've got the entire video available below. 

Since announcing the launch of the Jaguar F-type Coupe, we've been waiting for somebody to review it. Well, the great news is that the reviews have started and most people absolutely love it. Make no mistake, Jaguar has hit it out of the park with this beast. 

The Jaguar F-Type R Coupe puts down 542hp through its rear wheels. The supercharged 5-litre V8 engine is the same powerplant used in the XKR-S and XFR-S, neither of which is lacking any poke. There are key electronic and mechanical developments here, though, not least a structure that's 80 per cent stiffer than that seen in the F-type convertible and that's the real difference in the driving experience, it transforms the car. 

In the video below, EVO magazine gets to grips with the F-type Coupe R on road and track and delivers his verdict. With the Porsche 911, Aston V8 Vantage and Audi R8 all within touching distance, the Jag won't have life easy. And neither does its rear tyres when EVO has a go. 

The team at XCAR spent some time getting to grips with the all-new 2015 Jaguar F-Type R. With 543bhp, an angry 5.0-litre supercharged V8 and one of the best noises ever to fall out of a car, it's safe to say Jaguar's on to a winner. It's the car Jag should have been making for years.

Watch as Sutcliffe takes a brave pill and switches off all the safety systems to find out just how poised and well-balanced the new Jaguar F-type coupe is. Then look on in as he drives ex-F1 ace Martin Brundle's Eagle Jaguar E-type to trace this new car's history.

With a bargain price tag and supercar performance, the Corvette C7 Stingray has rebooted the iconic American sports car. But can it compete with Europe's best: the Audi R8, Porsche 911 and Jaguar F-type?

The seventh-generation Chevrolet Corvette. It marks the return of the Stingray; in name, at least. It certainly looks good on paper: all-new styling, chassis, cabin and - most importantly - the new LT1 V8 engine. But how does it fare against the best that Europe can offer? Can it out-accelerate and out-brake a Porsche 911? Does it sound better than a Jaguar F-type? Can it out-handle an Audi R8? Steve Sutcliffe referees the biggest sports car battle of 2014.

More recently our personal favorite car journo Chris Harris compared the new Corvette with the Porsche 911 Carerra S. Interestingly, Chris points out that the Corvette costs the same as the optional extras fitted to the Porsche. And it still does 190mph. Which wins?

The new Jaguar F-Type represents a return to the company's heart: a two-seat, convertible sports car focused on performance, agility and driver involvement. The F-Type is a continuation of a sporting bloodline that stretches back more than 75 years and encompasses some of the most beautiful, thrilling and desirable sports cars ever built. Joining the XK convertible and coupe models, the new F-Type provides Jaguar with a broader line of sports and GT models.

The 2014 Jaguar F-Type combines low vehicle weight (starting at 3,521 pounds), high power (340hp, 380hp and 495hp versions) and superb aerodynamics to achieve a pure sports car experience, yet with Jaguar elegance and luxury.

A true two-seat sports car, the all-new Jaguar F-Type is equipped with a modern, lightweight soft top that, when lowered, serves as its own tonneau cover. This not only provides a weight savings, but also improves packaging and contributes to the car's low center of gravity for greater agility. The top can be fully raised or lowered in just 12 seconds at speeds of up to 30 mph. Its multi-layer construction includes a Thinsulate® lining for optimal thermal and sound-insulating properties.

This is a prototype of the top flight Jaguar F-type R coupé, a 542bhp monster driven here by Steve Sutcliffe at Barcelona's Circuit de Catalunya. It's so good that after a few laps Sutcliffe thinks the car deserves comparison with the Porsche 911 Turbo.

Watch as Sutcliffe takes a brave pill and switches off all the safety systems to find out just how poised and well-balanced the new Jaguar F-type coupe is. Then look on in as he drives ex-F1 ace Martin Brundle's Eagle Jaguar E-type to trace this new car's history.

490hp, small, very pretty: is that enough to make the fastest F-Type a 911 rival? And would an Aston do the job of a Brit roadster better? This video by Chris Harris gives you the full rundown.
