Rolls-Royce Amethyst Droptail one-ups the floral theme with gemstones

Rolls-Royce debuted its first Droptail commission during Monterey Car Week, the floral-themed La Rose Noire. Not seven days later, the second Droptail took to the alpine stage in Gstaad, Switzerland, commissioned by a client wishing to celebrate his gem business, his home region, and his son. This one's called the Amethyst Droptail, the quartz crystal chosen for being the son's birthstone. The International Gem Society says February's gem ranges "from pale lilac to deep reddish purple," a symbol of royalty as well as "spirituality, mental clarity, and healing." We're also told the vivid stones are generally more valuable and desirable than the pale stones, hence the intense colors on the Amethyst Droptail.  There's another lilac connection in the Globe Amaranth flower native to Guatemala, Panama and Brazil, but grown all over the world. Rolls-Royce said this amaranth "blooms in the desert near one of the client's homes." The roadster starts with the soft purple body color dubbed Globe Amaranth and flecked with aluminum, contrasted with deep purple Amethyst paint swirled with a blend of red, blue, and violet mica flakes. Carbon fiber sections around the hem of the car display book-matched chevron patterns and are finished with Amethyst-tinted lacquer. More contrast shows in mauve accents painted inside the 22-inch wheel spokes. The brightwork's seen a great deal of attention. There are two finishes on the vanes of the Pantheon grill, each thin leading edge polished to a shine, the broadsides being brushed. The 3D-printed composite lower grille is affixed with 202 stainless steel ingots hand-painted in Globe Amaranth. Above that, a ring of rounded (as opposed to faceted) and polished amethyst surrounds the Spirit of Ecstasy when she appears. The stone's been finished into a shape referred to as a cabochon, generally featuring a convex upper surface and flat underside, and engraved with the word "Droptail." The interior is designed around the commissioning client's choice of Calamander Light wood, which features long bands of varying tones. Lighter bands decided the hue of the Sand Dunes leather on the seat bolsters framing the Amethyst leather centers. There are more amethyst cabochons laid around the gauges in the instrument cluster.

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.

Rolls-Royce Spectre electric coupe testing moves to sunny southern France

Rolls-Royce's first series-produced electric model is well on its way to production. Called Spectre, the big coupe is undergoing shakedown testing on and off the track in the sunny south of France, and the British firm announced that development work is about 40% complete. Going electric isn't an excuse for Rolls-Royce to stray from the reputation for excellence that it has earned over the past 116 years, so engineers are putting the Spectre through the most rigorous testing program they've ever subjected a new model to. We're told that, when all is said and done, the prototypes will have covered over 1.5 million miles of testing, which represents on average more than 400 years of use for a Rolls-Royce. Some test mules were sent to freeze in Sweden near the Arctic Circle, while others were shipped to the French Riviera. Testing in France will be split into two parts. First, the Spectre will be put through its paces on the track that Rolls-Royce parent company BMW operates in Miramas, a town located about an hour west of Marseilles. Engineers will notably get the opportunity to drive the prototypes on handling courses, on a 3.1-mile oval with steep banks, and in standing water. when they have passed every challenge with flying colors, the prototypes will be sent out to the picturesque roads that zig-zag through the countryside surrounding the test track. Rolls-Royce explained it's putting a tremendous amount of effort into fine-tuning the Spectre because the coupe packs more technology than any model it has previously released. It features "141,200 sender-receiver relations and has more than 1,000 functions and more than 25,000 sub-functions," according to the company, which is around three times more sender-receiver signals than in a typical Rolls-Royce. The Spectre will inaugurate a new suspension system that promises to take the firm's Magic Carpet Ride to the next level. It relies on technology that scopes out the road ahead and on data sent by the navigation system to decouple the anti-roll bars when needed, such as on a straight road, and recouple them as the car approaches a corner. The suspension system also gets firmer ahead of a bend. Rolls-Royce hasn't released powertrain specifications yet, and the Spectre's final design remains hidden by camouflage, but the few official numbers available are impressive.
