2019 Jaguar I-Pace gets official 234-mile range rating

The 2019 Jaguar I-Pace is officially rated to travel as far as 234 miles on a single charge of its battery pack. That's down slightly from the 240 miles initially promised when the slinky electric crossover was first unveiled here in the States. And, while it's roughly equal to the base version of the Tesla Model X, that's not exactly an apples-to-apples comparison. Quoting maximum electric range without considering the capacity of a car's battery pack is the same as quoting the maximum driving range of a gasoline-fueled vehicle without considering how many gallons of gas the tank holds. The I-Pace's battery pack is rated at 90kWh. The Model X's smallest pack is 75kWh. So the Tesla can go about the same total distance as the Jaguar using significantly less energy. It's not just Tesla that boasts greater efficiency figures than the Jaguar. Chevy manages to eke 238 miles out of the Bolt EV's 60kWh battery pack, and Hyundai gets 258 miles from the Kona Electric's 64kWh pack. These vehicles certainly don't all play in the same market segments, and there are a lot of variables to consider. For instance, the Jaguar's 4.5-second 0-60 rating is quicker than the Model X's 4.9-second rating, and its advertised power output of 394 horsepower and 512 pound-feet of torque is higher than Tesla's for the 75D (though Tesla's actual power numbers aren't really advertised in traditional hp and lb-ft figures). But even if cars like the Model X, Chevy Bolt, and Hyundai Kona EV aren't directly comparable across the board, their range and battery capacity figures do help us understand the relative efficiency of each specific vehicle. The efficiency of electric vehicles rated by the EPA is expressed as a MPGe (miles per gallon equivalent) figure. The 2019 Jaguar I-Pace's figures of 80 city, 72 highway, and 76 combined MPGe don't compare favorably with the Tesla Model X's 91 MPGe city, 95 MPGe highway and 93 MPGe combined ratings. It'll be interesting to see how much EV buyers care about the Jaguar's comparatively poor MPGe ratings, but they will definitely have an impact in the real world. In practical terms, what all of this means is that the Jaguar I-Pace is going to use more electricity per mile than the Tesla Model X. And that means it's going to cost more to drive the same distance in the Jag when compared to the Tesla, or just about any other modern long-range EV that's currently on the market.

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.

Question of the Day: What's the greatest British car ever?

The British automotive industry has produced everything from high-production econo-commuters to staggeringly luxurious oligarch-wagons, along the way winning plenty of races and building plenty of beautiful machines. The original Mini led directly to the past half-century of transverse-engine, front-wheel-drive cars built everywhere, the MGB put the sporty little convertible into everyone's reach, and the Morris Oxford became the most beloved motor vehicle in India. So many to choose from, but we want you to pick one. What will it be? Related Video:
