UX 300e

European premiere of the Lexus UX 300e, our first BEV

The new Lexus UX 300e is not only our first battery-electric vehicle (BEV) but the first production model produced under the Lexus Electrified strategy.

Originally revealed at the 2019 Guangzhou International Automobile Exhibition, the UX 300e was given its European debut at the Kenshiki Forum in Amsterdam in January. The new BEV is scheduled to go on sale in China and selected European markets later this year and in the UK by 2021.

Lexus UX 300e: principal features

Developed for excellent on-road performance, our engineers have preserved the distinctive design and convenience features of the Lexus UX compact SUV. They also focused on the opportunities to build on the performance advantages that are unique to EVs, thereby holding true to our ‘yet’ philosophy.

In these respects, the high-output, 150kW/300Nm motor of the new UX 300e provides natural yet brisk acceleration, the precise delivery of which can be modified through the Drive Mode Select function and four levels of deceleration and regeneration management.

The model’s high-capacity, 54.3kWh lithium-ion battery is located directly beneath the cabin floor to ensure a low centre gravity as well as optimum front/rear weight distribution. Similarly, strategic application of additional bracing and special shock absorber tuning to match the dynamic nuances of an electric car, have served to enhance the car’s already high-performance GA-C platform.

While EVs are naturally quiet in operation, the UX 300e goes further by adding insulation to suppress noises that would otherwise be noticeable in the absence of an engine and transmission. Engineers also addressed the sound generated when the vehicle is driven. Active Sound Control is used to transmit natural, ambient sounds to communicate driving conditions to the vehicle’s occupants. Nevertheless, the UX 300e will offer one of the most tranquil cabin environments in its class.

Lexus UX 300e: reliability and hybrid heritage

The knowledge we have gained from more than 15 years of industry-leading hybrid systems was applied in the development of the new Lexus UX 300e. This experience directly assisted us in maximising the efficiency of the motor, inverter, gears and high-capacity battery – in fact, the performance of the entire system – to deliver an anxiety-free driving range. The UX 300e achieves a range of 249 miles/400km in the correlated NEDC cycle, corresponding to a more than 186-mile/300km target range in the WLTP cycle.

For example, the battery is equipped with a sensitive temperature management system, while further monitoring systems regulate charging and prevent issues related to over-charging. It should therefore deliver outstanding battery reliability.

The engineering team has also adopted the latest connectivity technology to maximise the car’s everyday usability and functionality. By linking their smartphone with the Lexus Link app, UX 300e owners will be able to remotely check battery charge and driving range.

The app includes further controls, such as a timer to indicate when a full charge will be reached, and a charging schedule for when the vehicle is next expected to be driven or timed to commence when energy prices are low. It will also be possible to remotely tune the cabin climate before you jump in.

Distinctive design and high functionality

Lexus carried over the distinctive styling and high functionality of the UX compact SUV to the new UX 300e, developing new aerodynamic wheel designs and an underbody cover. Locating the shift-by-wire system on the centre console contributes to the simplicity and functionality of the interior.

True to Lexus’s prioritisation of new, advanced safety technologies and quickly making them available to customers, the UX 300e is equipped with Lexus Safety System+, helping in the prevention of accidents, injuries and fatalities. At the same time, the development of driver assistance systems helps reduce driver stress and promote a more natural and safe driving experience.

  1. Would you be able to confirm what type of charging connection this car has please and what is the maximum KW/h it can take on a fast charge?

    1. Hi Bryan,

      Thanks for getting in touch with us and for your interest in the new UX 300e. The charging speed for DC from 0% to 80% is 50mins and is a max 15kW. The type of charging connection used is CHAdeMO for DC charging, and ‘Type 2’ (or Mennekes) for AC charging.

      We hope this helps.

  2. What is needed is a genuine 480km range vehicle – the battery in the UX 300e is quite simply too small

    1. Hi Robert,

      Thanks for your message. We’re sorry to hear you’re not a fan of the UX 300e. When determining the range, we looked for the optimal balance between usage, package and cost. The average BEV driver in Europe covers around 26 miles per day. This means that with the current range, he will be able to drive the vehicle for a full week without recharging.

      Thanks.

      1. Not everyone likes big cars. A small car with limited range would work for me. But must be versatile and fun to drive.

      2. Hello there
        I think you have provided an answer to the wrong Robert. The point you have responded to was raised by a Mr Robert Jenkins, not me. Just thought I’d let you know so you could re-direct the answer to the right Robert.

      3. I don’t believe its about being a ‘fan’ of the car; I drive a Lexus and have the utmost respect for the brand quality and service. Whilst acknowledging your comment in terms of average drive, most households will take extended trips periodically that would require a charge en route. The state of the charging network in the UK is poor, until a Tesla like network is built buyers will look to the maximum range of their BEV, otherwise a second ICE car would need to be a consideration. If it were a straight choice of buying a Tesla or Lexus. Tesla wins on range and charging infrastructure hands down but build quality is shocking. To exploit the BEV sector surely stepping away from a city car would enhance the reputation of Lexus as a serious player in this area? As an aside, what are the results of DC rapid charging this battery in succession – does it suffer from ‘cold gate’ like the air cooled Leaf? And finally you have previously stated that CHAdeMO is widely available in Europe but it is really not the way forward as for example Ionity use the European CCS charging standard. My next car purchase will be BEV and would love it to be a Lexus but not sure this UX300e has enough all round capability for me; I’m sure it will work for some as a second car.

        1. Hi John,

          Thanks for getting in touch with us. Firstly, adding range and/or performance is technically not so difficult, but it would require some compromise on other elements such as price and package. We believe that with UX EV, we strike a competitive balance between package, range and performance, making the car an attractive option for more customers.

          Regarding rapid battery charging, even though the battery is cooled, and therefore runs less risk of being damaged by the high temperatures, there is always some increased battery degradation from high-speed DC charging.

          Finally, the reason is that we use CHAdeMO for DC charging, and ‘Type 2’ (or Mennekes) for AC charging, whereas some competitors use CCS (Combined Charging System) which uses the same connector for AC and DC charging (hence ‘combined’).

          By splitting the two charge-ports, we have an advantage in terms of design (two smaller ports on either side of the vehicle rather than one big port). But we also save some weight, since a combined charger is heavier.
          In addition, we will also offer both AC and DC chargers to our customers. To be amongst the first to receive the latest news on the UX EV, you can sign up to the mailing list here: https://www.lexus.co.uk/forms/registerinterest-ux-ev

          Thanks.

      4. People don’t want a car that is incapable of doing a return trip outside the city. You quote a range of 186 miles. In real conditions that’s probably closer to 120 miles. Allowing for range anxiety, you wouldn’t want to travel more than 80 miles. That’s not enough to visit my father’s house (90 miles) without stressing that the battery might run out.

        1. Hi Chatmandu,

          Thanks for getting in touch and sharing your thoughts with us. We are sorry you don’t think the UX 300e will suit you at this time. This is just our first BEV and we hope one day to offer another that would fit with your requirements in the future.

          Thanks.

  3. It is great that you are going to offer fully electric and they are sure to be super cars. I think the real breakthrough though will be the adoption of hydrogen powered cars with fuel cells. With the recent advances hydrogen fuel tanks this must now be a viable option. We just the need the infrastructure with hydrogen being produced next to renewable energy sources to reduce wasting energy by moving it around the grid. Your development in electric cars will not be wasted. Hopefully one day someone will make the hydrogen fuel tanks the same shape as the batteries so that some of the electric cars can be converted.

    1. Hi Andy,

      Thanks for getting in touch. It’s great to hear your interest in hydrogen fuel cell cars. Toyota Motor Corporation (parent company of Lexus) launched its fuel cell research and development programme back in 1992 and launched its first hydrogen fuel cell vehicle in 2015. While there isn’t currently a Lexus FCV, we do have an underlining commitment to have a hydrogen fuel cell car in our range and you can find out more about this using the links below:
