Lotus unveils $2M electric hypercar Evija (Type 130); 2,000 PS, 1,700 Nm
Lotus unveiled its electric hypercar, the Evija, formerly called the Type 130 (earlier post). Carrying a starting price of €1.7 million (US$2.1 million)—plus duties and taxes—the Evija is intended to be the most powerful series production road car ever built with output of 2,000 PS and 1,700 N·m. An ultra-lightweight carbon fibre monocoque also makes it the world’s lightest production EV hypercar at 1,680 kg (including the 70 kWh battery pack). Target 0-62 mph (0-100km/h) is less than three seconds, with a top speed of more than 200 mph (320 km/h) and a targeted range of 250 miles (400 km). The Evija is the first hypercar from Lotus, and the company’s first model with an electrified powertrain. It is also the first completely new car to be launched under the stewardship of Geely. Production is limited to not more than 130 units, making it among the most exclusive cars ever launched. It’s a figure set in tribute to the car’s project code, Type 130. The all-electric powertrain was developed with technical partner Williams Advanced Engineering (WAE). Key to the exceptional power output is the 2,000 kW lithium-ion battery, supplied with its management system by WAE as part of a joint venture with Lotus to collaborate on advanced propulsion technologies. WAE won a 2018 Queen’s Award for Enterprise for translating its EV expertise from the race track to road-going vehicles. The battery pack is mounted centrally behind the passenger compartment, and its cover is visible through the glass rear screen. This positioning delivers significant advantages in terms of styling, aerodynamics, packaging, weight distribution, occupant comfort and dynamic handling. It also supports fast and convenient servicing and maintenance. Furthermore, the set-up has been designed so that in the future alternative battery packs—for example, to optimize track performance—can be easily installed. Power is fed from the battery pack to a bespoke in-line axial arrangement of two high-power density e-motors. These feature integrated silicon carbide inverters and epicyclic transmission on each axle of the four-wheel drive powertrain. The motors and inverters being supplied by Integral Powertrain Ltd. Four exceptionally compact, extremely light and highly efficient single-speed, helical gear ground planetary gearboxes transfer power to each driveshaft. Measuring a mere 100mm in depth, each gearbox comes packaged with the e-motor and inverter as a single cylindrical Electrical Drive Unit (EDU), with a target power of 500 PS per e-motor. Torque-vectoring, enabled by the four e-motors, provides exceptional dynamic response and agility on the road. This fully automatic, self-adjusting system can instantly distribute power to any combination of two, three or four wheels within a fraction of a second. In Track mode the ability to add more power to individual wheels enables the radius of corners to be tightened, potentially reducing lap times. The Lotus Evija is equipped with ESP stability control to ensure safety in all road conditions, with further grip provided by the four-wheel drive system. A pure steering feel is assured via an electro-hydraulic system. Power can be delivered over a sustained period. The car’s advanced aerodynamics and four-radiator cooling package keep the battery at an optimum temperature. It means that the Evija is capable of being driven flat-out with no derate for at least seven minutes in Track mode. Through the partnership with Williams Advanced Engineering, the battery has the ability to accept an 800 kW charge. Although charging units capable of delivering this are not yet commercially available, when they are it will be possible to fully replenish the battery in just nine minutes. Using existing charging technology—such as a 350kW unit, which is currently the most powerful available—the Evija’s charge time will be 12 mins to 80% and 18 mins to 100%. The car is built on a one-piece motorsport-inspired carbon fibre monocoque chassis supplied by CPC. Constructed from multiple carbon plies, the manufacturing process is identical to that of an F1 chassis, and ensures the lightest, stiffest, safest and most technically advanced Lotus road car platform ever built. The total weight of the monocoque tub is a mere 129 kg. This chassis, coupled with innovative engineering and clever packaging throughout every element of the Evija’s powertrain, has contributed to the class-leading target weight of 1,680kg in its lightest specification. The Evija is the first Lotus road car to ever feature a full carbon fibre chassis. Moulded as a single piece for exceptional strength, rigidity and safety, the full length of the underside is sculpted to optimize downforce. It includes an integrated air diffuser which extends from under the B-pillars to the rear. Active aerodynamics are deployed in the form of a rear spoiler, which elevates from its resting position flush to the upper bodywork, and an F1-style Drag Reduction System (DRS). Both are deployed automatically in Track mode, though can be deployed manually in other modes. The absence of traditional door mirrors plays a part in reducing drag. Cameras integrated into the front wings are electronically deployed on unlock, while another camera built into the roof provides a central view. Images are displayed on three interior screens.

ZF presents new electric 2-speed drive for passenger cars
ZF has introduced a new 2-speed electric drive for passenger cars that integrates an advanced electric motor with a shift element and appropriate power electronics. The improvement in energy conversion efficiency compared to previous e-drives extends the driving range for each battery charge. The compact design also makes this new drive system of interest for passenger cars in the compact class. The modular design of this unit can also be fine-tuned and scaled up for use in sports and performance vehicles. For electric vehicles in everyday use, it is important to obtain as much range as possible from each battery charge. Every percent of improvement in energy conversion efficiency translates into two percent more range.—Bert Hellwig, Head of System House at ZF’s E-Mobility division To increase the performance rating of the new electric axle drive system, ZF leveraged its expertise in systems to develop a new electric motor with a maximum power rating of 140 kW paired with a two-stage shift element. Vehicles with the new 2-speed drive consume less energy, which in turn extends range by up to five percent when compared to a one-speed unit. Shifts take place at 70 km/h. By connecting to the vehicle’s CAN communication it is also possible—if the customer so wishes—to devise other shift strategies, possibly linked to digital map material and GPS. For example, the vehicle could identify from the GPS route programming how far it is to the next charging station, enabling it to respond predictively by switching into Eco-mode. More effective shifts would also be possible in accounting for topography on the interstate, and on inter-city journeys. The software in the drive can also be updated via the network link to Cloud services via over-the-air updates. For vehicle manufacturers, the new 2-speed drive offers two options for using improved energy conversion efficiency. The Original Equipment Manufacturer (OEM) could either go for an extended range while retaining the same size of battery, or utilize a smaller batter. The 2-speed concept also offers benefits for OEMs pursuing performance. Until now, with electric motors, vehicle manufacturers have had to choose between high initial torque and a high top speed. We are now resolving this conflict and the new drive will be compatible for performance and heavier vehicles—for example for passenger cars towing a trailer.—Bert Hellwig ZF’s modular approach combines the 2-speed gearbox with even more powerful electric motors rated for up to 250 kW. This delivers enhanced acceleration and, potentially, faster top speeds. With its modular concept, the new drive can meet a variety of requirements.

Adamas: lithium deployment in passenger EVs up 47% y-o-y in May 2019
In May 2019, 47% more lithium carbonate equivalent (LCE) was deployed globally in batteries of passenger EVs than the same month the year prior, according to Adamas Intelligence’s latest subscription-based “EV Battery Lithium Monthly” report. This increase in LCE deployment was driven primarily by two factors, Adamas said. Global sales of passenger HEVs, PHEVs and BEVs collectively increased by 12% in May 2019 versus May 2018, translating to an increase in deployment of li-ion batteries. Sales of high-capacity BEVs, such as the Tesla Model 3, BYD Yuan and Nissan Leaf PLUS/e+, made up a greater share of total passenger EV sales this year than they did last year, boosting the sales-weighted-average battery capacity of all EVs sold by 33% over the same period, translating to greater use of LCE per vehicle. In total, 47% of LCE deployed globally in passenger EV batteries in May 2019 went into NCM 523 cells (primarily in the form of lithium carbonate), up from 43% the same month the year prior. Similarly, 14% of LCE deployed globally in passenger EV batteries in May 2019 went into NCM 622 cells (primarily in the form of lithium hydroxide), up from 8% in May 2018. Moreover, 2% of all LCE deployed globally in passenger EV batteries in May 2019 went into NCM 811 cells (primarily in the form of lithium hydroxide) versus near-negligible quantities deployed the same month the year prior. In total, the collective market share of NCM 622 and NCM 811 cathodes (by capacity deployed) has doubled since May 2018, indicating increasingly heavy demand for lithium hydroxide and other precursors used in these chemistries.

Lightning Systems estimates that 140 to 160 vehicles will be ordered under the contract. Agencies, cities and counties interested in purchasing vehicles should consult contract number 1-19-23-22 (A-D) at www.caleprocure.ca.gov. All vehicles under the contract are eligible for special funding via the California Air Resources Board (CARB) Hybrid and Zero Emission Truck and Bus Voucher Incentive Project (HVIP). The voucher program can reduce the upfront cost of advanced zero emissions fleet vehicles by 40 to 70 percent. HVIP was formed by CARB to respond to a key market challenge by making clean trucks and buses more affordable for fleets. By offering point-of-sale incentives for clean trucks and buses, HVIP provides a streamlined approach for providing helpful incentives to fleets without waiting to submit proposals or complicated paperwork. Fleets receive the voucher discount at the point of sale while HVIP-approved vendors and dealers process the required documentation. In the last 10 years, HVIP has committed to supporting the purchase of 2,500 zero emission trucks and buses with vouchers requested by California fleets. CARB estimates that the total number of ultra-clean trucks and buses operating on California’s roadways will reach more than 7,000 over the next two years with more on the way, as demand for vouchers continues to grow. Since 2009, the program has helped more than 1,100 California fleets buy cleaner vehicles. HVIP is administered and implemented through a partnership between CARB and CALSTART (selected by CARB via a competitive grant solicitation).
