How car disguise works - and Kacher camo

Ever wondered how they disguise top-secret car prototypes? Admired the psychedelic monochrome fizz splattered across future BMWs? We did, so we dispatched CAR's European editor Georg Kacher to Munich to find the inside story on car camouflage.

The black-and-white disguise seen on contemporary BMW test cars, such as the BMW 1-series M Coupe Georg is standing next to, is a thin plastic film supplied by chemical giant 3M.

It's stuck on to the prototypes' bodywork, sometimes swollen by disruptive padding to mask sensitive shapes, while all BM hacks use standard dummy headlamps to hide the real lights. This is proving a popular disguise, and we now see other brands, such as Jaguar, using similar disruptive pattern material. 

Where's Georg Kacher?

Aha! You haven't spotted our towering Austrian journalist yet? That's because we wrapped him in reams of the BMW's black-and-white 3M-supplied disguise.

The stuff's so malleable we managed to hide most of Kacher's 6ft 8in frame. Honestly, the car camouflage is so effective, we think you'll agree he melts quietly into the backdrop of BMW's Fiz R&D think-tank in Milbertshofen, a suburb of Munich.

Car prototype camo: the background

Every car maker disguises prototypes when they operate on public roads or tracks, to stop nosy bystanders and professional auto spies papping their future wares. In this digital age, scoop photos and spyshots are disseminated globally in a matter of minutes.

Murray Dietsch, Jaguar Land Rover's vehicle line engineering director, said it's essential to disguise test cars, as knowledge about future product could damage sales of existing model ranges - and alert the competition to your plans.

'We use hard plastic cladding and body camouflage to try and disguise the final shape, so you don't know what it's like,' Dietsch told CAR. 'But we need to continue testing these prototypes and the disguise must not stop the car working normally. Furthermore, we often need to take a car from one workshop to another - so it must be easily removed for our engineers to work on it.'

Of course, there is a delicious irony here: 99% of onlookers would probably fail to recognise a prototype if it drove past them undisguised. Adding weird camouflage probably does more to attract attention than to disperse it.

'It's a doubled-edged sword,' admits Dietsch. 'But you only get one chance to make a good impression when you launch a car. It only takes one car to be photographed near launch and you lose all that build-up. Secrecy is still very important to us.'

Now, where is Kacher?

That's him on the right, by the way. He assures us this is not his usual Friday afternoon garb for an evening on the tiles in Munich's shadier nighteries.

Honda CR-Z Mugen (2011): the first sketches

This is our first glimpse of the new, Mugen-tweaked Honda CR-Z. Developed by Mugen Euro, the UK-based arm of Honda's long-standing tuning partner Mugen, this CR-Z features a whole raft of tweaks to turn it into a hot hybrid.
As with the previous UK-spec Civic Type R Mugen, this new Mugen model is currently being touted as a one-off prototype, but just as that Civic was then built in limited numbers the same may happen with the CR-Z – and the individual parts may become available as aftermarket accessories too.
So how will Mugen Euro turn the Honda CR-Z into a CR-Z Mugen?
The two sketches released so far give us a taste of the visual tweaks that Mugen Euro is planning. The carbonfibre bonnet is obvious, and together with Mugen alloy wheels, will help save weight. The CR-Z Mugen will feature new front and rear bumpers too, and a new rear spoiler, no doubt inspired by the Mugen-tweaked CR-Z available in Japan. Other Mugen-spec parts include bespoke brakes and suspension components.
There are a whole host of upgrades planned for under the skin too – the Japanese Mugen CR-Z doesn't have any engines tweaks. Mugen Euro promises 'enhancements' for the 1.5-litre i-VTEC petrol engine, and the IMA hybrid system, boosting power and torque. And Mugen Euro is hoping that together with induction and exhaust upgrades, it may actually be able to improve on the standard CR-Z's 56.5mpg and 117g/km CO2. Not bad when Mugen promises the petrol-electric powertrain will offer 'Type R-like performance'.
'We wanted to extend the performance of the CR-Z,' said Mugen Euro vice president Hiro Toyoda. 'It is already a fun car to drive, with an excellent chassis, but we thought that with more power and enhanced torque delivery it could be even more exciting. However, as with all Mugen projects, we have stayed true to the Honda design and philosophy, and the electric motor is still a vital ingredient to boost performance and economy.'
The Honda CR-Z Mugen will make its world debut at the Goodwood Festival of Speed in July 2011.

BMW 1-series M Coupe (2011) MotoGP safety car

BMW's M Division has unleashed a track version of its upcoming 1-series M Coupe, which made its debut as the 2011 MotoGP safety car at the season-opening MotoGP race in Qatar on 20 March.
BMW 1-series M Coupe MotoGP safety car – the lowdown
Visually there have been some changes over the roadgoing 1M, which is due to go on sale in April 2011. The new louvred bonnet is made from carbon fibre, there's an additional front splitter fitted to the bumper, plus polycarbonate side and rear windows, and an adjustable rear wing. There's a light bar on the roof for official signaling duties and the package is wrapped in a suitably-loud M colour scheme
Inside there's a partially stripped-out interior with a bolt-in roll cage replacing the rear seats, a pair of lightweight Recaro racing buckets up front with six-point harnesses, and a fire extinguisher.
The suspension gets a track upgrade with adjustable dampers and suspension geometry to suit each of the 18 MotoGP circuits. Black 19-inch wheels and tyres (255/35 front and 285/35 rear) hide uprated six-piston fixed-caliper racing brakes.
The only major part of the car left unmodified is the drivetrain. Under that vented bonnet sits the standard 3.0-litre, 335bhp turbocharged straight-six engine, coupled to a six-speed manual transmission. 
MotoGP? Wouldn't they have a safety bike? Why use a BMW 1-series M Coupe?
And just where on a safety bike would you fit the light bar? BMW M has been supplying support vehicles to MotoGP since 1999, with the 1-series M Coupe marking 13 years as official supplier. Apart from the 1M, BMW has also supplied an X6M and an M3 as reserve safety cars for 2011. The MotoGP organising team has been given a BMW X5M for the safety officer and a BMW ActiveHybrid X6 for the stewards. The MotoGP medical car is a BMW 535i Touring, and providing additional support are two safety bikes: a BMW S1000 RR and a BMW HP2 Sport.
Any chance of a harder, faster 1-series M Coupe?
Very little. BMW's M Division has considered both a convertible and CSL version of the 1-series M, but its engineers are doubtful there's demand for the former, and if the case couldn't be made for an M3 CSL then the latter (potentially priced at the same level as an M3) won't see the light of day either

BMW M5 (2011): new F10 super saloon scooped

BMW will launch the new M5 in 2011, the super saloon variant of the F10-series new 5-series family. Our artist's impression reveals how the hot Five will look at launch next March, after a show debut in late 2010 or early 2011.
We have the full four-page lowdown from Georg Kacher in the latest January 2010 issue of CAR Magazine, but here are some nuggets to whet your appetite:
4.4-litre V8 bi-turbo
578bhp, 530lb ft
155mph limited top speed
0-62mph 4.4sec
Unlimited top speed 188mph
That direct-injection 4.4 lump is the same engine you'll find under the hood of the X5 M and X6 M, but further tweaked by M Division to liberate more power. Forced induction makes it the first M saloon to be turbocharged.
Will there be a new BMW M5 Touring?
Not this time. Dog owners in a rush will have to shop at the neighbouring Audi or Mercedes showrooms for RS and AMG variants.
We interview Klaus Draeger in the new issue of CAR Magazine, and he discusses the need to downsize and explains how even the new M5 will benefit from Efficient Dynamics.
New M5 cleans up its act
Yes, even BMW's fastest saloon now concentrates on lowering its CO2. Internal targets are gunning for a 30% drop in emissions and consumption.
Find out exactly how BMW has achieved that and read about the latest Munich developments in active aerodynamics in the latest January 2010 issue of CAR Magazine, on sale now.

BMW M3 pick-up (2011)

This, believe it or not, is a pick-up version of the BMW M3. Our spies have just snapped it testing at the Nurburgring, but it's not the first M3 pick-up either...

Is it test mule for the next-gen BMW M3?

Good question, but unfortunately not. Sadly, it's not a production car either – BMW hasn't produced a Touring version of the current M3 because it didn't think there would be enough demand, and there certainly wouldn't be for this pick-up version either.

Instead, this M3 pick-up is the result of M Division's engineers asking 'what if?'. Apparently it started as an after-hours project, and although there are no current plans for production, we hear the Z3 M Coupe started its life the same way...

This M3 pick-up isn't the first M3 pick-up built by M Division either. When CAR visited M HQ back in 2007 the engineers had a battered 1980s 3-series with its rear-end chopped up to form a pick-up bed, and under the skin was the four-cylinder engine from an E30 M3 and the requisite limited slip diff. Our guide, workshop boss Jakob Polschak, mimed a few opposite-lock heroics, before an engineer threw some rubbish in the back, fired it up and headed off to the tip...

With BMW being media savvy, it's not surprising that the car has appeared at the 'Ring, even if the 3M-supplied disguise does little to hide what this car is.

Vauxhall Astra VXR (2011) spy photos

This is Vauxhall's new hot hatch, the near-300bhp Astra VXR that our spies have just snapped testing at the Nurburgring.

A 300bhp Vauxhall Astra VXR? Even post-Focus RS that's still a lot of power for a hot hatch...
It is. VXR Astras have always boasted more power than the equivalent Focus ST, and with the new fast Ford only offering up 247bhp this hot Vauxhall will comfortably surpass that. The Astra VXR uses a turbocharged and direct injection 2.0-litre four cylinder engine, and will produce around 290bhp, while Vauxhall's trick HiPerStrut front suspension, FlexRide adaptive damping system, and an electronic differential will do their best to control all the power going to the front wheels.

Beyond that there's a six-speed manual gearbox, fully uprated suspension, a big brake kit, chunky bucket seats, a VXR bodykit, and VXR interior trimmings.

What's the Vauxhall Astra VXR based on?
Vauxhall's new three-door Astra, which was previewed by the Paris GTC concept unveiled last year at, err, the Paris motor show. The new three-door Astra should retain the GTC tag, and will appear this summer with a motor show debut at the 2011 Frankfurt motor show. The Vauxhall Astra VXR will be revealed in spring 2012.

Artega SE & GT (2011) at the Geneva motor show

German sports car maker Artega brought the current GT and the SE, an electric version of the obscure man's Cayman, to the 2011 Geneva motor show.
Artega… remind me who they are again?
Artega was founded in 2006 in Dalbruch, Germany with the involvement of Karl Heinz Kalbfell, a well-known industry executive formerly of BMW, Rolls-Royce, Alfa Romeo and Maserati (he's now at Lotus).
VW supplied Artega with their 3.6-litre V6 engines and DSG transmissions. Henrik Fisker was involved in the design of the GT, which appeared in concept form at Geneva 2007, before the production version was released in Frankfurt that year. Georg Kacher drove the GT in 2008 and came away extremely impressed.
But then the global recession hit, and demand for well regarded but little-known sports car brands tumbled. Artega is currently owned by the Mexican private equity firm Tresalia Capital. You may have heard of another firm they have a stake in: Modelo Breweries, makers of Corona beer.
Artega SE – the electric Artega
The familiar body and aluminium spaceframe remain on the Artega SE, but the VW engine disappears, replaced with two electric motors generating a total of 280kW of power.
A 37kWh lithium ion polymer battery pack provides a claimed New European Driving Cycle (NEDC) range of 300km, with a minimum of 200km under 'normal driving conditions'.
Artega has maintained a 43:57 weight balance with the EV coupe, in spite of the 115kg weight penalty over the GT model thanks mainly to the battery packs. The Artega SE goes from 0-62mph in 4.3 seconds - half a second faster than its V6 stablemate - and top speed is quoted as 'over 155mph'.
At least you won't have much time to worry about range anxiety at those speeds.
Artega's sales plan
Artega has capacity to build up to 500 of the electric sports car a year, at a cost of €140,000 (£119,000). That's ambitious – Tesla has managed to sell 1500 roadsters between 2008 and 2010, and Artega is only beginning to expand its dealer network, initially in Europe.

Mini Coupe JCW (2011): the latest spy photos

BMW (and thus Mini) is particularly media savvy, so as the launch of the new Coupe fast approaches, the disguise on the company's test vehicles is gradually being stripped away to reveal the concept-aping shape of the production cars. Our spies have just snapped the John Cooper Works version on test in Europe, giving us a close-up look at the hottest version of the new Mini Coupe.

I'm not sure whether to love or hate the new Mini Coupe…

On the one hand it's another variant of an existing car, and the roof design doesn't exactly look practical. On the other, development costs are so expensive that spinning more and more cars off one platform is the name of the game these days. More importantly, there's a lot to like…

The existing Mini hatch isn't exactly practical but this car will ditch its siblings useless rear seats and uselessly small boot for one bigger, more practical load bay. Carryovers from the hatch are go-kart handling (even more sporty in Coupe guise, we hear) and top-notch interior quality.

When do we get to see exactly how closely the new Mini Coupe mirrors the concept car?

Mini will unveil the Coupe this summer, with the new car's motor show debut coming at Frankfurt in September 2011 and UK sales starting shortly afterwards. At launch we hear they'll be Cooper, Cooper S and John Cooper Works variants, all powered by Mini's latest 1.6-litre petrol 'four'. The naturally aspirated Cooper will produce 121bhp, while the turbo'd Cooper S and JCW will manage 181bhp and 208bhp respectively.

The nose of this new Mini will be identical to the hatch, and our spies have snared the JCW variant with its beefier bumpers and extended sills. It's the same bodykit that the concept wore, and as you can see from our side profile comparisons the production car will change very little. The exotic roof keeps its backwards-baseball cap styling (though we hear it will now be made of steel rather than aluminium to ease production at Plant Oxford), the steeply raked windscreen stays, and there's now a pop-up rear spoiler to aid stability too.

Goodwood Festival of Speed 2011 preview

Lord March has kicked off the countdown to the 2011 Goodwood Festival of Speed at the annual press preview.

The theme is Racing Revolutions - Quantum Leaps That Shaped Motorsport. Lord March said it meant a mouth-watering array of cars, celebrating tech advances such as 4wd, carbonfibre and monocoque construction.

Naturally, there are a number of anniversaries to celebrate: the centenary of the Indianapolis 500 race, 100 years of Chevrolet, the Jaguar E-type's golden birthday and 110 years of Skoda motorsport involvement.

'We'll be the main focus for Indy 500 celebrations outside the US,' said Lord March. 'We'll have more than 20% of cars that ever won the Indy 500.'

A range of other events will add the rich diversity that made Goodwood motorsport so famous. The supercar run continues, there's a Rolling Motor Show on the Thursday (with more than 23 car makers signed up) and the FoSTec pavillion will showcase eco cars.

The Festival of Speed runs from Thursday 30 June to Sunday 3 July 2011.

Tim Pollard's updates from the 2011 Goodwood Festival of Speed preview

• It's a dry day at the Goodwood press preview. Join CAR as we wonder around and see some of the cars coming to the 2011 Festival of Speed.

• What's this? A Nissan Leaf going up the hill - backwards! It's a stunt to show that it's as fast in reverse as it is going forwards. Being driven by stunt driver Terry Grant. Hampered by a 40kph limiter, it'll be removed for the festival as they seek a new, backwards speed record up Lord March's front drive.

• The press preview is like a mini festival in its own right. There can only be a couple of hundred media and sponsor guests - and a whole load of cars to ogle as they run up the hill for demo runs. We're off down to the start line to watch.

• In keeping with the 2011 theme, there are a brace of Jaguar E-types, and its spiritual successor the XKR-S making its dynamic debut. Sadly Jag aren't doing passenger rides. Must seek my thrills elsewhere.

• Bruno Senna has agreed to take me up in the Lotus Evora S. Wristbanded up, I wait for my turn, spotting some of the more interesting machinery lining up on the startline. There's some poor bundle of nerves in a Caparo T1, preparing for certain terror next to Mikka Hakkinen. The SWB Audi Quatro, a Lancia Stratos, McLaren MP4-12C, Tesla Roadster... The list goes on.

• My time is approaching to accompany Senna up the hill. He's staying in the Evora, as there's a chill in the air. I climb in, and we talk about F1, the film about his uncle Ayrton ('it's really moving, a great movie'), and his new company car: an Evora S like the one we're sitting in. 'I'll have mine in a dark colour, not yellow,' he tells me. 'I'll stand out in Monaco too much.'

• Strapped in, we inch towards the start line. I attach a video camera to capture it for CAR Online and suddenly we're off. Damn, this supercharged one is fast. We squirm as the rear wheels scrabbles for grip on the Goodwood startline. I'm pushed back hard and brace myself as we approach the first corner. I've not driven the S only the basic Evora , but it's bloody quick. That trad Lotus ride quality is intact and Senna throws the car into the corners before Goodwood House. He fluffs a couple of gearchanges, but we still hit 110mph past the house. Then it's hard on the brakes for Molecomb and we're slowed down as the hillclimb is truncated for press day. There sadly aren't enough haybales to run flat out to the top. It's quite a ride.

• The man from TAG Heuer whisks me aside to show me its original 100-year-old first car timer. It's normally kept in a Swiss museum - looks like a giant stop watch or ship's clock, and accurate to one second.

• Tag Heuer has struck a deal to time at the Festival of Speed. After the crashes in the 1990s, they won't be timing full runs or doing speed traps, but rather doing a 100m standing start - with points for the most brutal getaways. Turns out Anthony Reid scored the fastest start in a Jaguar XF-R. Of course, in Goodwood parlance that's 'the most spirited getaway.'

• Ferrari's heard that golfer Nick Faldo has bought a McLaren MP4-12C. They're desperately shunting the golfer into a 458 Italia for a run up the hill. Perhaps he'll have one of each.

• Few details emerging about the 2011 Goodwood Revival. There'll be a separate E-type-only race broken out of the TT. A 45-minute, two-driver race. And as it's the Spitfire's 75th anniversary, there'll be a special celebration at its former airbase. 'We are hoping to have a record for the most number of Spitfires in the air at one time since WW2,' said Lord March. 'We should have 15 to 18.'

Porsche 911 GT3 R Hybrid (2011) first official pictures

Porsche has released details of its updated 911 GT3 R Hybrid – the 2010 original nearly won last year's Nurburgring 24hr race before (ironically) it retired with petrol engine failure. 

The 2011 Porsche 911 GT3 R Hybrid – the lowdown

Before this report disappears in a chorus of 'it looks the same as last year's one', let's outline where Porsche's engineers have been busy. At the unfashionable end of the car remains a 4.0-litre flat-six engine producing approximately 470bhp. Up front are twin electric motors, now producing 75kW of power each (up from 60kW) and combined these give the GT3 R Hybrid a 197bhp electric boost, which can be programmed to activate automatically via the throttle pedal, or manually selected during overtaking.

F1-derived hybrid tech for the 911 GT3 R Hybrid

Power for the two electric motors doesn't come from batteries, but flywheel accumulator technology from Williams Hybrid Power, an offshoot of the Williams Formula 1 team. The flywheel, encased in a carbonfibre safety cell in the space where the passenger seat would be, spins at up to 40,000rpm and acts as a mechanical energy store for the electric motors. Regenerative braking feeds energy back into the flywheel system – no surprises there, as the technology is derived from Williams' exeprience with Kinetic Energy Recovery Systems (KERS) in F1.

GT3 R Hybrid - lighter, brighter and optimised for 24-hour racing

Outside there have been aerodynamic tweaks to that familiar racing 911 form.  Improvements to the hybrid system cooling mean the louvers ahead of the rear wheelarch disappear, reducing drag. The car is also 50kg lighter, now weighing in at 1300kg – meaning it's also 70kg less than the roadgoing (and petrol-only) 911 GT3 RS. Porsche has managed to reduce the weight of the hybrid components by 20% too, and although it claims the new racer is no faster than before, it is promised to be more fuel efficient.

The stripped-out interior features a button- and display-laden steering wheel and backlit centre-console buttons, all laid-out for ease of use by the drivers, particularly during night racing. Glowing green headlights mean that rival drivers won't mistake the GT3 R Hybrid when it's hunting them down around the Nurburgring at night.

Has the hybrid 911 got much chance of winning on the racetrack?

Definitely. The GT3 R Hybrid was leading the Nurburgring 24-hour race and looking likely for victory in 2010 before retiring due to engine failure less than two hours from the finish. Porsche will be hoping the internal-combustion side of its hybrid racer holds together for the full race distance this year.

What's New
