Lexus, renowned for the manufacture of luxury cars, is owned by the Japanese automotive behemoth, Toyota Motor Corporation. Lexus was created in 1989 to compete against Japanese rivals, Honda Motor Company and Nissan Motor Company, who had established their premium brands, Acura and Infiniti, respectively. However, work on the Lexus concept commenced as early as 1983.

The Lexus brand is now a well recognised global automotive brand in the premium segment, with its luxury cars sold in more than 90 countries. The United States continues to be its largest market. Though Lexus is relatively late to the global electrification (EV) race, the company has been involved with hybrid technology since 2005, the year the hybrid version of the RX crossover made its debut. The company has been a leader in ‘self-charging hybrid cars’. The company currently has 8 vehicles that use hybrid/ plug-in hybrid technology and has only one battery-electric vehicle (BEV). The company has the following plug-in electric vehicles (EVs):

The compact Lexus NX crossover SUV was introduced in 2014. Since its release, the SUV has sold well, to include becoming a best-selling SUV in Europe. The Lexus NX SUV is available as a ‘self-charging’ and a plug-in hybrid electric vehicle (PHEV).

The PHEV was launched as part of the broader second-generation launch of the SUV in 2021. The Lexus NX PHEV is the first plug-in hybrid vehicle from the Japanese automotive manufacturer and shares the same powertrain as the RAV4 plug-in hybrid.

The Lexus PHEV has a respectable 18.1 kWh onboard EV battery, with a claimed zero-tailpipe emission electric range up to 64 km (WLTP certified). This is certainly higher than the average PHEV (the average is closer to 40 km). However, the real-world EV range will be lower, impacted by a number of factors, to include: driving profile, speed, passenger load, weather, road condition, wheel size etc. Assuming a 54 km emission-free electric range is more realistic, which will be sufficient for most commutes. The EV also has regenerative braking to increase the electric range.

Do keep in mind that driving on e-mode is much cheaper than calling on the internal combustion engine (ICE). Depending on where you charge the EV, pure electric driving will cost between 5 cents to 10 cents per km. In fact, the more the EV is driven on the pure electric mode, the better is the overall fuel economy of the vehicle. The manufacturer claims that the Lexus PHEV has a fuel economy up to 1.1 l/100 km. To achieve anywhere close to the claimed economy, driving the plug-in electric car on EV mode will be imperative.

If most of your driving is on the motorway, with limited use of the onboard EV battery, then the fuel economy will be closer to a conventional internal combustion engine (ICE) variant (6 l/100). Having said that, the Lexus NX PHEV can still be leveraged for shorter motorway travel. Of course, the NX 450+ EV also leverages the Lexus self-charging hybrid technology for better vehicle efficiency.

The NX plug-in has a 6.6 kW onboard charger. The EV battery can be fully charged in 2 hours 45 minutes using a 7 kW dedicated home EV charger. Yes a 3-PIN domestic socket can be used for charging the EV, however, we at e-zoomed discourage the use a domestic socket for charging an EV. Also faster and safer to use a dedicated EV charger. For public charging, the EV will still continue to use AC charging, as the PHEV is not DC charging compatible. Most PHEVs do not offer DC charging compatibility.

The all-wheel drive NX PHEV pairs a 2.5-litre petrol engine (4-cylinder) with an electric motor. The electric motor is placed at the rear of the electric vehicle (EV), enabling all-wheel drive (AWD). On EV mode, the e-SUV can achieve a top speed of 135 km/h. The NX 450+ plug-in SUV can achieve 0-100 km/h in 6.3 seconds (maximum power: 306 hp). The top speed on the EV is 200 km/h. As is the case with electric vehicles, the NX PHEV benefits from instant torque.

When on electric mode, the tailpipe emissions are zero, however, when using the internal combustion engine (ICE), the SUV has tailpipe emissions between 21 – 25g CO2/km, far lower, compared to the conventional combustion engine variant (147g CO2/km).

The Lexus Safety System+ comes as standard. The higher trim levels offer: blind spot monitor (BSM), rear cross traffic alert and braking (RCTAB), adaptive variable suspension (AVS), smart entry and start system, 20″ alloy wheels, 14″ touchscreen display, sunroof and more. The PHEV uses the latest infotainment system from Lexus, a significant improvement compared to the previous generations.

Bottom-line, electric driving is good for the environment and the wallet!

History Of Electric Cars: Quick Facts

An electric vehicle (EV), also referred to as a battery-electric vehicle (BEV) is not a new invention or even an invention of modern times. Indeed, EVs were first developed more than a 100 years ago in the 19th century. Inventors from various countries, to include European countries and the United States, were the first to invest in electric motors and batteries. The first practical electric cars were built in the second half of the nineteenth century, with the first US electric car introduced in 1890.
Electric vehicles came into prominence in the early 1900’s, a time when horse-drawn carriages were the primary mode of transportation. Archived black and white photographs from that period show famous avenues like Madison Avenue in New York city filled with horse-drawn carriages. In stark contrast, a similar photograph taken a decade later of Madison Avenue showed not a single horse-drawn carriage. Instead the avenue was filled with motor vehicles, a new invention. It was the beginning of man’s love affair with cars that has lasted more than a century and still going strong. 
However, the uptake of electric vehicles in the early 20th century was short-lived, as gasoline powered vehicles propelled by internal combustion engines (ICE) become the preferred mode of transportation. Bottom-line, manufactures chose internal combustion engines over electric cars in the early 1900s for various reasons, to include, the costs and production volumes.  
It is not definitive as to where EVs were invented or to credit a single inventor. However, one known electric motor (small-scale) was created in 1828 by Anyos Jedlik, a Hungarian inventor, engineer, physicist and Benedictine priest. Hungarians and Slovaks still consider him to be the unsung hero of the electric motor.  
Shortly after, between 1832 and 1839, a Scottish inventor Robert Anderson created a large electric motor to drive a carriage, powered by non-rechargeable primary power cells. Through the 19th century a number of inventors were inspired to develop electric motors to include, Thomas Davenport, an American from Vermont credited with building the first DC electric motor in America (1834). Unlike many of his contemporaries and other trying to build electric motors, Davenport did not have a background in either engineering or physics. In fact, he was a blacksmith. 
Move forward a few decades and at the end of the 19th century, William Morrison created what is believed to be the first practical electric vehicle. Morrison, another American from Des Moines, Iowa, was a chemist who became interested in electricity. He build the first electric vehicle in 1887 in a carriage built by the Des Moines Buggy Co. His first attempt was not a great success. In 1890, he attempted again, with more success. 12 EVs were built using a carriage built by the Shaver Carriage Company.
The batteries were designed and developed by William Morrison. The vehicle had 24 batteries with an output of 112 amperes at 58 volts that took 10 hours to recharge. Available horsepower just under 4 horsepower. The vehicle could accommodate 6 individuals and had a top speed of 14 mph (22.50 km/h).
Morrison’s success led to others also developing large-scale practical electric cars. At the turn of the century cities like New York had 60 electric taxis. The first decade witnessed strong popularity for electric vehicles. However the popularity was short-lived as internal combustion engine (ICE) gasoline powered vehicles replaced the early electric vehicles. Henry Fords success with the then ubiquitous Ford Model T was the ‘beginning of the end’ for electric vehicles. The Model T was cheaper than the prevailing electric cars (US$ 650 Vs US$ 1,750) and could be manufactured at scale.  As they say — the rest is history.
