All 789bhp of the McLaren Senna prototype is unleashed at Silverstone, Bentley's new Continental GT wafts onto the streets, and BMW's silent i8 Roadster is driven for the first time. Mercedes-Benz's huge G63 AMG also rocks up. Finally, Brabham finally unveils the £1.2m BT62. Mira Orange Senna flies around Silverstone. Image credit: Autocar McLaren Senna prototype Anyone remember the P1? Of course you do. 903bhp pedalled 1375kg of hybrid V8 madness around, and 640kg of air was happy to help out with sticking the whole thing to the track. Well this time, you've got no batteries, no electric motors, and no 'form over function' thinking here. McLaren accepts that this isn't the nicest thing to look at, but anyway, the 720S is one of the best looking cars of the decade, and that's £550k less, and not sold out. Anyway, here you have 789bhp, 590lb-ft of torque and 800kg of downforce. Dry weight? A bag-of-crisps-like 1198kg. That's courtesy of a f

Porsche's 911 GT3 RS is tested and Mercedes gets a new engine for the E-Class and a new rival for the S-Class: the Polestar 1. Porsche 911 GT3 RS review: can the perennial irritatingly good sports car hold its own on track? Annoyingly, it can. 513bhp and a screaming 4.0l naturally-aspirated flat-six tends to do that. The headline figures are the redline of the engine and the extraordinary power squeezed from a relatively small engine. That's 20bhp more than the standard car and the same 9,000rpm limiter, but a new, GT2 RS-derived aerodynamics package and a substantial £143,000 pricetag. So is it worth it? Lizard Green is a bold colour choice. Picture credits: Evo The 991.2 911 GT3 RS has lapped the Nürburgring already , in a scorching 6:56.4, thanks to all the new aero gubbins and the extra power. That is faster than the 875bhp 918 Spyder, and is also known as progress. "It climbs through the 7 gears with a lively fervour, the engine scaling the stairway t

Brabham Automotive has risen from the deep, Porsche records a scorching laptime at the Nürburgring, and two new hatchbacks are driven: the Suzuki Swift Sport and the Mercedes-Benz A-Class. That rear wing contributes to a huge 1200kg of downforce Brabham BT62 Brabham is one of those names that make a Formula 1 fan spontaneously combust with excitement. Their mix of innovation, cheeky rule-bending and records to their name sets the knees of any petrolhead trembling. Founded by Sir Jack Brabham, he managed to make himself the first driver to win a championship in a car bearing his own name. Their most famous car was the BT04, using a fan to physically suck the car towards the track. They're back. They're back with this, the BT62, and the headline figures, much like the Dallara Stradale  are of high downforce and a tiny dry weight. 972kg is all that keeps the car on the ground at standstill, but at 155mph, an extra 1200kg is happy to help. 1200kg. That is the highest downf

The new Aston-Martin Vantage hits the streets, and Ford takes the wraps off its new Focus. Chevrolet's Camaro gets a mid-life uglification. New Aston Martin Vantage  Aston Martins are a bit like Subway sandwiches. They don't tend to be spot on the first time you try, but with time and careful honing, they grow on you and the final result is fantastic. And, with no 'Comfort' mode and a lazy automatic gearbox, the new Vantage seems like it will follow suit. However, things aren't quite as they seem with this one. Although Astons are typically luxurious and genteel GT cars, the Vantage was launched in a decidedly un-luxurious and un-genteel shade of lime green (the car on the right in the first photo). It also ditches any rubber damping on the mounts for the engine and gearbox, and so, despite resting on a modified DB11 platform, is far more like a sports car in principle. Take the engine, for example. 503bhp and 505lb-ft is exactly the same as the Merc-AMG C6

2018's new Le Mans Prototype contenders arrive and manufacturers announce hybrid next generation performance cars. The WEC is my favourite racing series. My special favourite is the 24hrs of Le Mans, due to the last-minute rivalries and overtakes, reliability troubles, madly brave drivers, the spaceships in the LMP1 and LMP2 classes, and the fact that it stays exciting through the whole 24(!) hours. Well, the LMP1 racers have just dropped, and it turns out that, although Audi ended an 18-year career as the most successful team ever and Porsche turned its back on two consecutive wins to both enter the electric Formula E series, the tragic tale of Toyota leading LM two years ago and breaking down on the final lap will live on. Toyota is sticking in the game for yet another year. Toyota's contender is once again called the TSO50, and is once again powered by a 2.4l twin-turbocharged V6, with the obligatory flywheel, battery or supercapacitor boost, with Toyota opting f

All the best from the New York Auto Show 2018. The NY show this year was, despite the Koenigsegg Regera poster car, not festooned with hypercars and track specials. The focus was more on practicality, with two pairs of classic rivals fighting it out for the sales advantage, if we're being brutally honest. Jaguar and Maserati both unveiled performance versions of their first SUVs, while Mercedes-AMG and Audi went into classic super-saloon warfare. The RS5 has been timed at 3.2s to 62, proper supercar pace. The Audi RS5 Sportback is a 4-door version of the dull Coupé version, and so is just as powerful, nearly as quick and slightly heavier, at 1840kg. That means 444bhp, 443lb ft of torque, 0-62mph in 4.1s claimed. You can read the whole story on it by clicking  on these words. These two are classic saloon rivals, representing sensible vs stupid. The Mercedes C63 has been given a mid-life facelift, and by clicking on the link, you can learn the 503bhp monster's whole s
