Mclaren Artura Defining The New Hybrid Supercar Rulebook

---

Roughly eight years ago, McLaren kickstarted the hybrid-electric supercar race with the magnificent yet unhinged P1. The Artura succeeds the P1 as McLaren’s ultimate hybrid supercar, but the new Artura is not a replacement for the P1. For starters, the McLaren Artura has less horsepower than the P1. It is also more “economical,” with base prices starting in the $225,000 range, much less than the P1’s astronomical $1.5 million asking price.
Despite this, Artura is truly special. It’s the first series-production High-Performance Hybrid supercar from the British automaker. Artura is also the first McLaren to be built on the brand’s all-new McLaren Carbon Lightweight Architecture (MCLA). As a footnote, the MP4-12C is the first production car designed and built wholly by McLaren, and every McLaren since then has been based on the 12C’s carbon-fiber composite chassis.
In essence, Artura is new from the ground up, and it swims in the same ocean as the iconic P1 due to its plug-in hybrid electric powertrain. “Every drop of McLaren’s experience and expertise has been poured into the Artura,” said Mike Flewitt, McLaren Automotive CEO. “Our all-new, High-Performance Hybrid delivers all of the performance, driver engagement, and dynamic excellence for which McLaren is renowned, with the additional benefit of EV driving capability.”
McLaren Artura: Styling & DesignForgive me for nitpicking the styling this early on. I think McLaren played it safe in designing the new Artura, but that’s just me. However, I understand the reasoning behind this. As mentioned above, Artura replaces the 570S in McLaren’s lineup and NOT the P1, so we’re talking about a base-level McLaren, for lack of better words.
So yes, Artura is a new car even though it uncannily resembles every vehicle in McLaren’s portfolio. But look closer, and you’ll find Artura’s cabin is a bit different. Also, the body lines are more purposeful than the P1, while the wheel arches are more dramatic and defined.

It also has built-in electrical heating, ventilation, and air conditioning. This new ethernet electrical system supports over-the-air updates, reduces cabling by 25 percent (to cut weight), and speeds up data transmission. It also controls the standard advanced safety systems like adaptive cruise control, lane-departure warning, auto high-beam assist, and road-sign recognition.
In so many words, the McLaren Artura represents what you might call a software-defined car. This approach helps lower weight and increase performance, both of which are necessary for a vehicle like the Artura.
McLaren Artura: Powertrain SpecsSay what you want about the styling, but every McLaren since the legendary F1 has been all about the motor. The Artura combines the best of both worlds. It has a new dry-sump aluminum and turbocharged M630 3.0-liter V6 gas engine pumping out 577 horsepower and 431 lb-ft. of torque.
The hybrid part is courtesy of a compact axial flux electric motor inside the transmission bell housing, generating 94 horsepower and 166 lb-ft. of torque. The combined 671 horsepower output is a small number compared to the mighty P1’s 903 horsepower hybrid powertrain, but Artura has an ace up its sleeve.
The Artura’s V6 gas engine weighs only 353 lbs. and is 110 lbs. lighter than a comparable McLaren V8. It can also spin to 8,500 rpm. Meanwhile, Artura’s electric motor has a 33 percent greater power density per kilo than in the P1. The motor sips power from a small 7.4 kWh battery pack. The total weight of the hybrid components tips the scales at just 287 lbs. All in all, Artura has a curb weight of 3,303 lbs. which, according to McLaren, is on par with comparable supercars that do NOT have a hybrid powertrain.

Zero to 60 mph takes three seconds flat; zero to 124 mph happens in just 8.3 seconds; zero to 186 mph takes 21.5 seconds. McLaren quotes a 205 mph top speed for the Artura. Meanwhile, Artura’s all-electric range is an acceptable 19 miles, exactly the same as the P1’s EPA-rated 19 miles of range in EV mode.
No Reverse Gear, No Problem!That’s right. The McLaren Artura has no reverse gear. Instead, it uses the electric motor to slide in reverse. Artura has a standard eight-speed dual-clutch automatic transmission governing its hybrid powertrain, turning the rear wheels via an electronically controlled differential or E-diff. Cleverly located inside the gearbox, this E-diff handles torque distribution across the rear axle to improve traction and handling.
The driver gets to fiddle with four Powertrain modes, including Comfort, Sport, Track, and EV. Also, Artura has separate handling modes to finetune the damper settings and electronic stability control system.
The Artura employs a carbon-ceramic braking system from the same family as the 600LT and 720S. The discs measure 15.4 inches at the front and 15 inches at the rear and work in conjunction with the new rear axle design.

Apparently, this setup maximizes stability and reduces understeer out of a corner while accelerating, said McLaren.
Equipped with wider Pirelli Cyber Tires with hardware and software integrated into Artura’s electrical architecture, each rubber features an electronic chip generating real-time data, all of which are relayed to Artura’s stability control system to enhance tire performance. Simultaneously, those high-tech tires have sound-absorbing devices in the tire wall to significantly reduce road noise while improving driving comfort.
As an added plus, Artura has a lightweight and fully-redesigned hydraulic power steering that works in conjunction with McLaren’s Proactive Damping Control system. Carbon-ceramic brakes with lightweight aluminum calipers offer relentless high-speed braking power and stability.
Driver-Centric InteriorThe all-new Artura benefits from two high-definition screens powered by McLaren’s latest MIS II interface. The infotainment system supports Apple CarPlay and Android Auto connectivity and features a new version of McLaren’s track telemetry and Variable Drift Control apps. The driver gets a redesigned navigation map in the instrument cluster. Power-operated Comfort Seats are standard, while Clubsport bucket seats remain optional.
McLaren Artura: Pricing & AvailabilityThe McLaren Artura has a base price of $225,000 and is offered in three core specifications: Performance, TechLux, and Vision. The Artura is available to order now, with the first customer deliveries arriving in the third quarter of 2021. The new Artura comes with a five-year vehicle warranty, a six-year battery warranty, and a generous 10-year body warranty.
