The Ferrari 812 GTS is the world’s most powerful convertible

Ferraris new 812 GTS has just taken its top off to win the title of most powerful production convertible and reopens a bloodline that hasnt been on the books since the 60s.Ferrari was pretty late to the game with this one, waiting for Aston Martin, Lamborghini and Bentley to release wind-in-your-hair versions of their cars before revealing this drop-top Superfast in early September.But none of that matters now, because Modena has reclaimed the crown for the most powerful convertible. It might sound hard to believe, but its been 50 years since Ferrari has offered a production front-engined V12 convertible. Yes, the 365 GTB Daytona was the last car to have the honour, but the V12 has come a long way since Colombo worked his magic.The honour now, of course, comes courtesy of its 6.5-litre V12, which makes 789 horsepower and 530 lb.-ft. of torque. The engine can nail 8,900 rpm in the blink of an eye, and hit 100 km/h in under 3.0 seconds; 200 km/h in just 8.3 seconds; and rush onward to a top speed of 340 km/h. As for the top itself, it can be raised or lowered in just 14 seconds at speeds up to 50 km/h. When lowered, flying buttresses fill the gap behind your head.Ferrari also recently debuted the drop-top version of its brand-new F8 Tributo, with a 710-horsepower V8 thats guaranteed to mess up your perm.The F8 Tributo is not a revival of the classic Ferrari layout but follows a long, unbroken lineage of rear-engined V8 supercars with drop-tops.All the excellence of looking like Sonny Crockett will cost you, however; the 812 GTS starts at 336,000 ($488,609) and goes up from

News Roundup: How to steal a Tesla in 30 seconds, what Lambo’s most powerful car looks like and more

Welcome to our weekly round-up of the biggest breaking stories on Driving.ca from this past week. Get caught up and ready to get on with the weekend, because it’s hard keeping pace in a digital traffic jam.Here’s what you missed while you were away.Tesla thieves fool key fob system to make away with vehicleIt looks ridiculously simple. Two men walk into the yard of a home in a town near London, England, one holding a home-made wire antenna above his head, the other standing near the driver’s door of the Tesla. Less than 35 seconds later the two are off the property with the car. So what kind of top-secret hacker voodoo did these two employ to pull off this efficient heist? Actually, thanks to the fact Tesla and many other vehicles rely on key fob tech that actively transmits a signal that can be picked up by the right antenna in the right place, they probably didn’t use anything you couldn’t pick up at your local electronics store.Learn more about why you should always store your key fob in a safe space. Report suggests next-gen Subaru WRX STI will arrive fall 2020 with new 315-hp engineAccording to reports by a Japanese car site, Subaru plans to have the 2021 WRX on streets by next fall. The fifth-gen sedan will allegedly ride on a new platform – the same to be used on all Subaru vehicles moving forward, including the upcoming WRX STI, Japan’s WRX S4 and the Levorg wagon – and use a new direct-injected FA20 four-cylinder with 315 horsepower in place of the current turbo-four EJ25 in North America. A reveal has yet to be announced.Hennessey’s latest kit for the 2020 Mustang GT500 makes 1,200 horsepower The 2020 Ford Mustang isn’t even out yet and Hennessey Performance Engineering has already come up with three aftermarket kits to make the pony buck with a little extra spunk. The Hennessey GT500 Venomis the latest kit announced by the famous, horsepower-crazed tuning brand.

The new hybrid Sián is the most powerful car Lamborghini’s ever produced

Lamborghini, long the maker of fodder for bedroom-wall posters, has whipped up yet another jaw-dropping creation. In keeping with the current trend of bestowing unpronounceable names on hypercars, this ones called the Sin.Oh yeah its also the most powerful Lamborghini ever produced.Deploying a claimed worlds-first use of a supercapacitor in a hybrid powertrain, the Sin produces a staggering 819 horsepower. Adopting a V12 engine as all Lambos should, in your authors opinion makes sense, but theres also a 48 volt e-motor incorporated into the gearbox to provide immediate response and improved performance.The company says this is the first time in any low-voltage hybrid that a direct connection has been made between electric motor and wheels. The V12 is rated at 785 horses, while the e-motor chips in for 34 ponies. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power, so itll probably skirt things like Londons congestion charge. I know anyone who can afford a Lamborghini doesnt really care about such an expense, but it sure makes for great bragging rights.But back to that supercapacitor. Besides sounding like a Bond weapon, it brings some innovative hybrid tech to the table its used for energy accumulation rather than a lithium-ion battery, for example. The unit is said to be three times more powerful than a battery of the same weight, and three times lighter than a battery producing the same power. Located in the bulkhead between cockpit and engine helps keep the cars weight distribution in check. The electric system, supercapacitor and e-motor weighs only 34 kg, with alert readers recognizing this means a remarkable weight-to-power ratio of 1.0 kg/hp. In fact, the whole car has a better power-to-weight ratio than the Aventador SVJ.All this adds up to a run to 96 km/h from rest in less than 2.8 seconds, according to Lamborghini. The company claims the e-motor fills in power gaps during gear changes, which are lightning-quick anyway.Expect the Sin to appear at this years Frankfurt IAA Motor

Lotus reveals 1973bhp Evija as world’s most powerful production car

Lotus has revealed the Evija, the all-electric hypercar it claims will be “the most powerful production car in the world”. An output of 1973bhp is promised when it hits roads next year, which is more than the upcoming 1888bhp Pininfarina Battista and Rimac C_Two, and the 1479bhp internally combusted Bugatti Chiron currently in production.  No more than 130 of the two-seat hypercars will be built, each priced at £2.04 million. “Target specifications” include four-wheel drive, 1254lb ft and torque vectoring, giving it a 0-62mph time of less than three seconds, a 0-186mph time of less than nine seconds and a top speed of 200mph-plus. A production slot can be reserved with a refundable £250,000 deposit.  The Evija, apparently pronounced ‘E-vi-ya’, will be Lotus’s first new-model launch under Geely ownership, and is the maker’s first all-new model for more than a decade. It will be made at the company’s traditional home in Hethel, Norfolk, and will act “as a ‘halo’ for the rest of the Lotus range” both now and for “new Lotus performance cars to come”.  The car pictured here in a studio is for show, but Lotus’s design director, Russell Carr, told Autocar that “this is how it’ll be on the road. This is very much the production car. All the surfaces are made to production level.”  The Evija, which is codenamed Type 130, is low and broad, at 4.59m long, 2.0m wide and 1.12m high. According to Lotus, it “marks the beginning of a contemporary new Lotus design language”.  “We wanted from the start to do something that was pure, simple, but have a sense of luxury and elegance about it,” said Carr. “On the outside, we started by thinking ‘what are the existing factors from the Lotus DNA that we want to keep?’, and really important for us were the strong haunches you see on the car. It’s very important when you’re sitting inside that you can see the corners of the vehicle – it helps you place the car on the track. It’s also just a very emotional thing to see the bodywork; rearwards as well.”  “We have the cabin sat low within those fenders, which are really important to us because the car’s all about dynamics,” said Carr, “and if the cabin sits low and the fenders are pronounced, you have the impression that the car’s got a low centre of gravity.”  Around the overall design simplicity come some advanced aerodynamics (see Carr QA, below), which direct air flow over, under and through the car, creating a complex body shape with vast scoops running through the rear three-quarters, and exiting at the back.  The design is permitted by the adoption of electric drive. “That certainly gives us a lot more freedom, yes,” said Carr. “You’ve obviously got battery packs that can be placed in certain places, and it’s certainly different from a traditional combustion engine, and we’ve tried to exploit that as much as possible.”  Lotus hasn’t yet revealed how many electric motors the car will have or where they’ll be positioned, but its partnership with Williams Advanced Engineering – which is, among other things, the supplier of batteries to the Formula E grid – will be key to the Evija’s performance.  Lotus said the Evija will have a 70kWh battery, capable of being charged at up to 350kW, enabling an 18-minute charge with a WLTP range of around 250 miles. The charge port is at the rear of the car.  Construction is from carbonfibre, both for the chassis and the body. Light weight is core to all Lotus models and the Evija weighs several hundred kilos less than the Battista and C_Two are reported to be, although they have more battery capacity. Even so, at 1680kg, the Evija is likely to become the heaviest Lotus ever. Despite this, Lotus boldly claims it will “set a new standard for Lotus driving performance” and be “the most dynamically accomplished road car in the history of Lotus”.  Inside, the carbonfibre construction remains visible in what’s a relatively spacious cockpit. “The start point is a floating beam, this open instrument panel you can place your hand right through,” said Carr. “The inspiration for that came from classic racing cars, from the 1950s and ’60s, in which you can see the structure. In those days it would have been tubular, but on this it’s carbonfibre.  “We wanted to use carbonfibre, and once we got into that we started looking at wishbones on racing cars. We looked at modern racing bicycles as well, and that informed some of the sections and forms that go in there. And that’s really become a very distinctive part of this interior. If you love modern racing bikes or componentry on racing cars, you’ll recognise that.”  “It’s a nice shape to use as well, with the wing profile, and adds a strong aeronautical flavour on the whole car. It’s very distinctive,” Carr added. “There’s a certain luxury to space and in such cars you can feel very claustrophobic. This feels open.”  That’s in stark contrast to another upcoming hypercar, the Aston Martin Valkyrie, with the implication that the

Mercedes-AMG unveils most powerful four-cylinder engine ever

The world’s most powerful 2.0 litre, four-cylinder series production engine has been revealed by Mercedes-AMG, set to feature in its upcoming ’45’ model range.  Developing 415bhp in its most potent ‘S’ form, this completely new 2.0 turbo replaces the engine in used in the previous A45 A-Class, CLA45 and GLA45. Despite the potency of the outgoing A45 355/376bhp AMG four, engine development boss Ralf Illenberger says that emission requirements, the desire for more power, less weight and the different packaging requirements of Mercedes’ latest generation of compact cars necessitated a complete redesign. “The only carryover parts are a few nuts and bolts.” The new M139 engine produces 382bhp in standard form and  415bhp in ’S’ form, and 354lb ft or 369lb ft of torque. Another major aim has been extracting a sportier driving experience from the engine by altering its torque delivery. While the previous, M133 four cylinder engine’s torque curve resembled a diesel’s, rising steeply to level off across a wide chunk of the rev range, the new M139 2.0 produces more of a crescendo of thrust. The aim is to produce the rising rush of acceleration characteristic of a revvy, normally aspirated engine. Rather than flat-lining, diesel-style, from around 2000rpm, AMG’s new engine generates peak torque at 5200rpm, while nevertheless producing more shove than the old between 1000-2000rpm, the strongest surge developing from 3000rpm. Overall, says Illenberger, “it produces a more sporty delivery.” More diesel-like are the 160 bar combustion pressures generated by the new unit, and a lighter yet more robust cylinder block developed to withstand them. It’s of the closed deck variety, creating a crankcase casting more like a part-closed box rather than a semi-open one, with deep, strengthening skirts around the cylinders. The new alloy block is as strong as a diesel engine’s, says Illenberger. The 16-valve cylinder head is also new, a key design challenge being the dispersal of the considerable heat generated. Larger exhaust valves and valve seats, a redesigned water jacket, oil, water and air chilling for the turbo and separate coolant plumbing for the cylinder head and  cylinder block allow more efficient and protective control of under-bonnet temperatures, assisted by electrically controlled water pumps. The head itself features ‘Camtronic’ variable inlet and exhaust valve control and dual injectors per cylinder. A single piezo-injector per cylinder would be at the upper limit of its fuel volume delivery, says Illenberger, so a second quartet of injectors sits within the inlet manifold tracts to boost delivery under hard acceleration. The Camtronic system enables two camshaft profiles to provide a blend of good fuel economy and heightened throttle response. The vanes of a sizeable turbocharger run in low-friction roller bearings, an electric wastegate minimising the loss of boost when pressure modulation is required. The turbo now lives between the engine and the front bulkhead, the cylinder head having been turned through 180 degrees in order to fit the engine beneath the lower bonnet lines of the new models. The turbo’s new location requires extra cooling, some of this provided by and engine cover shaped to direct fan-generated airflow over it. Illenberger says that the electric water pumps may also function after the engine has been switched off, to cool the block, head and turbo. The more potent ‘S’ version sometimes harnesses the air conditioner for cooling too. Besides designing an all-new engine AMG has also developed a more streamlined way to make it. Each engine is still built under the ‘one man, one engine’ approach long used by the company – there are several women hand-assembling these engines too, incidentally – the methods of electronically recording the sequence of and torque applied to each power-tool-attached component streamlined to save time. The new arrangement also improves assembly ergonomics. The new methods cut the production time by 20 to 25%, says plant manager Alexander Kurz, enabling AMG’s four-cylinder manufacturing facility to produce 140 engines per day over two shifts. The first car to feature this unit will be the A 45 in July, the CLA 45 saloon appearing near-simultaneously, the GLA 45 a little later.
