Lunaz electrifying classic cars with coachbuilt, millimeter precision

One day last year, as David Lorenz waited by the side of the road for repair help with his classic car, he had an idea: Why not update all of that ancient mechanical "character" with a modern electric drivetrain? That would give an owner the beauty of the past, the mechanicals of the present, and the powertrain of the future. Jaguar does it with the E-Type Zero, and Aston Martin's in the game with the reversible EV powertrain swap for the DB6 Volante. And so Lorenz founded the British engineering firm Lunaz Design, named after his daughter Luna and headquartered at the Silverstone Technology Park. The company's first products are almost ready for order, starting with a 1953 Jaguar XK120 and a 1961 Rolls-Royce Phantom V. Lunaz conversions aren't a matter of pulling an engine and installing a battery pack; Lunaz reengineers classics. Managing Director Jon Hilton oversees a team bringing experience from carmakers such as Aston Martin, Ferrari, Jaguar, McLaren, and Rolls-Royce, with Hilton's resume including six years with Cosworth Engineering followed by eight years in Formula One. To develop the Lunaz offerings, a chosen car is stripped to the metal and weighed so that engineers understand the weight distribution at each corner, then the car is stripped to the chassis and 3D-scanned. This yields information allowing designers to create a powertrain that fits to the millimeter and stays true to the handling dynamics of the original vehicle. During the rebuild, the company says, any imperfections are remedied "using traditional coachbuilding techniques." The Jaguar and the Rolls-Royce get battery packs in two locations, one under the hood and one under the trunk floor. Lunaz says it can fit more battery for its in-house design into each car that way. The Jaguar's 80-kWh battery feeds two electric motors sending 375 horsepower and 516 pound-feet of torque to the rear wheels. The Phantom V uses a 120-kWh battery pack, but its output hasn't been released. While remaining true to the exterior and interior design of each car, Lunaz fits LED lights and modern tires, a modern suspension, better brakes with regenerative braking, power steering, an upgraded propshaft, and a fly-by-wire throttle. Safety and comfort additions include cruise control, traction control, and anti-lock brakes. Inside, the instrument cluster gets battery gauges, there's modern climate control, an infotainment screen with satellite navigation, and a Wi-Fi hotspot.

Jaguar envisions future without V8 engines

With tighter emissions and fuel economy regulations looming, Jaguar may have to do more than make a small, fuel-efficient hatchback to lower its model range's consumption figures - it also might give up its venerable V8 power, Drive reports. But not anytime soon, says Steven de Ploey, Jaguar's product and marketing director, who recognizes that the V8 can be replaced only by something that offers the same, or better, performance. But he has a word of caution: "We are not wedded to V8s."
In the meantime, de Ploey says there are other ways to reduce emissions. One of the first steps Jaguar could take is to shift away from the use of superchargers, which aren't as good as turbochargers at maintaining efficiency and making power. But he adds that supercharging still is "at the heart of Jaguar's performance proposition," and that the company has addressed the current downsizing trend by "replacing our naturally aspirated V8 with a 3.0-liter supercharged V6."
Consider one of de Ploey's comments on the cancelled C-X75 supercar (pictured) for some clue about Jaguar's future: "Some of the stuff we have already exploited to the extreme in the C-X75 is the kind of thinking for us and is an essential test bed to see how we could evolve from today to something that is sustainable in the future."

2014 Jaguar XKR-S GT takes fiercest feline further [UPDATE]

If there were any car to overshadow the 542-horsepower Jaguar XJR that's coming to the New York Auto Show, this is it. Meet the Jaguar XKR-S GT - a street-legal, higher-performance version of the already hardcore XKR-S that will be headed to North America in very limited quantities. Only 30 will be offered on our continent, with 25 earmarked for the United States and the remaining five going to Canada. The cost of entry? $174,000 when it goes on sale this August.
What that gets you is a coupe that is, without any doubt, ready to attack any racetrack it might encounter. The XKR-S' supercharged 5.0-liter V8 has not been upgraded in terms of power - not that 550 horsepower and 502 pound-feet of torque is anything to sneeze at - but instead, Jaguar focused on tuning the bits of the car that help effectively put all that grunt to the ground. There's a new hood with rows of louvers to aid in engine cooling, and elsewhere on the car's body, you'll find carbon fiber on the redesigned front air splitter, dive planes, extended wheel arch spats, as well as a new rear diffuser, an aluminum front under tray and an absolutely massive wing out back to keep downforce to a maximum.
Underneath that hot body are retuned and height-adjustable adaptive dampers; spring rates have been increased by 68 percent in front and 25 percent at the rear versus a standard XKR-S. Most of the front and rear suspension geometry has been upgraded, larger carbon ceramic brakes have been fitted at all four corners, and wider 20-inch forged alloy wheels are found here, wrapped in Pirelli Corsa tires - 255/35-series rubber in front and 305/30-series stuff out back. There's also a revised active exhaust system, which should only improve the already thunderous roar coming out the back of the Jag coupe, and a faster steering rack has been added for improved agility.
