Petrolicious examines a very special Jaguar C-Type

There are rare Jaguars, and then there's this stunning C-Type Lightweight Le Mans. Built in response to the dominance of the Mercedes-Benz 300SL at the 1952 24 Hours of Le Mans, Jaguar made only three C-Types for 1953 and managed to capture first, second, and fourth. These cars featured four-wheel disc brakes – a rarity at the time even in endurance racing – and a lighter aluminum body. The two SU carburetors were swapped out for three Webers, meaning more power and, according to RM Sotheby's David Swig, better throttle response. Swig would know. In the latest video from Petrolicious, he takes the fourth-place C-Type for a ride, giving us a look at the sleek open-roof racer in action, while our ears enjoy the delicious sound of the 3.4-liter, twin-cam straight-six. "What I love about these cars is how communicative they are on the road," Swig told Petrolicious. "How when you're going through a corner, you feel in the seat of your pants and through the steering wheel every little movement, every little pebble that you drive over." Beyond the driving experience, there's something to be said of the historical seat Swig is occupying. "No less than five Le Mans-winning drivers of this period have sat behind the wheel of this car," Swig said, "which almost give you goosebumps." Should you have the money, you can actually put this iconic racing Jaguar in your garage. RM Sotheby's will offer it for auction as part of its glitzy Monterey Car Week event next month. While you can look forward to our coverage of that event come August, you can enjoy the sight and sound of this iconic C-Type in the latest episode from Petrolicious.

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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
