COMPUTER-BASED VIRTUAL ENGINEERING Chas already helped compress vehicle development times and reduce costs. It allows complex engineering solutions to be packaged and tested before a physical prototype has been built, and many car makers now hold highly detailed digital models of their complete cars, and their tyres. Some anticipate that the next step will be to use these models to drive them virtually in a simulator instead of building early, physical engineering prototypes.
That's the view of Horiba MIRA, the research and development business based near Nuneaton in the Midlands, which has just opened a new £4million driving simulator complex. Its centrepiece is a VI-grade DiM250 Dynamic Simulator, pictured here, which is one of the world's most advanced multi-axis simulators.
Building the first physical, driveable prototypes of a brand-new model is both expensive and time-consuming, and the learning that results from driving and testing them is not definitive. This is because they are often hand-built from a combination of design intent and non-intent parts and so can be unrepresentative in significant areas such as structural rigidity. Also, if engine and gearbox development is ongoing, early drivetrains will also be unrepresentative, while chassis components may also be fabricated rather than 'off-tool' and the set-up will be best guess.
Yet despite their lack of maturity, these early prototypes are valuable for confirming proof of concept and may also highlight unforeseen issues. The first drive is a significant milestone in the development cycle of a new model, a real watershed moment, offering the first insight into the dynamic character of the car, how it performs against expectation, what areas are to target or on the right trajectory, and which will need more focus or even a rethink. You need to be able to see beyond the crudeness of the prototype to identify the potential, and that takes skill and experience.

BMW M135 xDrive
The M135 has lost an and gained chassis revisions and a restyle. Is it enough to make it a benchmark hot hatch?
Audi S5
S5 by name, S4 by nature, is Audi's new mid-size petrol-powered saloon a step in the right direction?
Lamborghini Urus SE
Lambo's super-SUV gets a major mid-life overhaul, going hybrid in the process. Has it become any easier to like?
HALL evo OF FAME
The evo Hall of Fame was established to recognise the great and the good of our corner of the universe. Prepare to welcome this year's inductees
CIRCUIT DAY
After three days of assessing their behaviour on the road, it's time to head to the Circuito de Navarra to find out how our nine contenders respond when their handling limits are explored
EVO CAR OF THE YEAR 2024
Nine brilliant cars, from flyweight roadsters to bombastic supercars to a be-stickered estate(!), do battle on some of Europe's finest and most spectacular roads. Which will emerge victorious? Place your bets now.
Porsche Panamera GTS
It lacks the raw power of its hybrid rivals, but does the new GTS’s more traditional approach give it its USP?
Alpine A290 GTS
The new electric Renault 5 has won plenty of plaudits. Is the hotter Alpine version a car to win petrolheads' hearts too?
BEST BUYS BMW M CARS
THE PERFORMANCE CAR LANDSCAPE WOULD HAVE looked very different over the last five decades without BMW. Its M division, founded in 1972, has produced some of the best driver’s cars ever to hit the road, and in the process has provided a stream of benchmark models for its rivals to chase. In recent years, stricter emissions regulations, downsizing and electrification have seen some of those rival cars falter, yet by and large BMW’s M machines have remained strong. In fact, some rank among the greatest the department has made think of the eCoty-winning M2 CS and M5 CS while others are the only options worth recommending in their respective segments. Price tags have risen with performance, however, putting those latest offerings out of reach for many, but the marque’s popularity means there are numerous earlier M models available on the second-hand market for far more attainable figures. Here are four of our favourites.
