We say Insane 500bhp 8.3-litre V10-powered muscle car that's also overpriced, unrefined and lacking in quality. Still, that's a big engine eh?Performance The SRT 10 – known as the Viper everywhere but the UK – has an enormous 8.3-litre V10 engine powering it. The 500bhp unit is enough to propel the two-seat roadster to 60mph in 3.9 seconds before it peaks at a top speed of 190mph.Emissions Emissions and fuel economy figures are difficult to come across for the latest engine however on the identically powered, same size engine of the previous generation, the SRT 10 returned just 13mpg and emitted an eye-watering 489g/km in CO2 emissions. It’Driving The SRT 10 is a short car but it feels massive because of its huge snout which is required to house the huge powertrain. It’s low slung so it feels settled when scorching along in a straight line however as soon as you turn the wheel it has a tendency to flick out at high speed, especially as there are few driver systems.Feel Steering is light and agile on the SRT 10 and its suspension setup aids that by being firm and crisp. That means it’s fairly poised around bends if you can control it but it’s uncomfortable and solid over bumps and potholes.Space It’s a two-seat roadster so despite being enough room for two occupants to travel comfortably, there’s little storage around the cabin. There’s a decent sized boot at the rear but practicality and comfort doesn’t rank highly on the list of priorities forEquipment As mentioned there are almost no driver aids other than ABS and the cabin reflects that back to basics feel. There’s a CD player, electric windows and mirrors but not a lot else.Price The Dodge SRT 10 comes in at £80,000 – that’s a lot of power for the money but not enough refinement or interior quality in our book.Quality Like all Dodges, the interior is dull and uninspiring on the SRT 10 – despite the £80,000 price tag. There are higher-quality materials than on any other model from the American manufacturer but there’s still too much cheap plastic in the cabin.Safety The SRT 10 comes with limited safety equipment, which is quite worrying for a car this powerful. Things like traction and electronic stability control (ESC) systems – which are standard on most cars in the SRT 10’s price range – are not available at all.Pros Brilliant performance figures.Cons There are numerous flaws to the SRT 10: It’s overpriced and underequipped in terms of technology in the cabin and safety equipment. It’s incredibly expensive to run. The interior is dull and dreary. There are far better alternatives on the market.Alternatives Corvette C6, Porsche 911
