Peugeot is part of the Netherlands based Stellantis N.V., which was formed by the merger of Fiat Chrysler Automobiles (Italian/ American) and Groupe PSA (French). You may not be familiar with these names, but the automotive brands in the portfolio would be well known to most consumers. These include: Maserati, Opel, Vauxhall, Jeep, FIAT, Alfa Romeo etc.

Peugeot was founded in 1810 in Eastern France (Sochaux), and has a rich heritage in motor racing and the broader automotive sector. Peugeot has won many awards for its passenger cars, to include, six European Car of the Year awards.

As part of the broader Groupe PSA, Peugeot is very committed to the electric vehicle (EV) sector. Peugeot has committed to offering a fully electric (BEV) or a plug-in hybrid vehicle (PHEV) for every model in its portfolio by 2023. The company’s portfolio of electric vehicles (EVs) include:

The Peugeot 408 PHEV Fastback

The new plug-in hybrid electric vehicle (PHEV) from Peugeot, the 408 PHEV, does beg the question, what body type is it? The electric vehicle (EV) is a blend of a coupé-SUV, crossover and an estate, with an attractive fastback exterior sloping roofline.

A ‘Fastback’ or a ‘Sportback’ or any other similar exterior styling continues to gain in popularity, with both automotive manufacturers and consumers, and we do expect this momentum to continue.

For those with a keen eye on electric cars, the Peugeot 408 may look familiar. In fact, it is! The 408 PHEV shares much in common with the Citroën C5 X plug-in hybrid. Citroën is also owned by the same parent company, Stellantis N.V.

It is now common for automotive manufactures to leverage the economies of scope, by sharing an underlying development platform across brands and models. End result, lower production costs, which translates to lower retail prices. The 408 also has elements from the Peugeot 308. The Peugeot 408 uses the EMP2 V3 platform, which is used to develop both petrol and electrified powertrains.

Peugeot is keen for the 408 to standout and it certainly does. In fact, the design team at Peugeot took seven years to complete this project. The vehicle is available as a conventional internal combustion engine (ICE) and a PHEV. Though Peugeot has not confirmed as yet, it is expected to also be available in due course as a battery-electric vehicle (BEV). For those new to electric cars, a BEV is a pure electric car and only runs on battery power!

The 408 PHEV has a 12.4 kWh onboard EV battery. It is an average EV battery size, that we have come to expect from manufacturers for plug-in hybrids, however, some of the newest PHEVs offer an onboard EV battery size closer to 20 kWh. Therefore, a little disappointing, in that, Peugeot does not offer the EV with a larger onboard EV battery. In general, the larger the EV battery capacity, the longer the pure electric range.

Peugeot claims the 408 plug-in hybrid has a zero-tailpipe emission electric range up to 41.6 miles (WLTP) on a full charge. However, the real-world electric range will depend on a number of factors, and will certainly be less than the claimed range. For those new to electric driving, these factors include: driving profile, weather conditions, road surface, wheel size, onboard services used, passenger load and more.

Expect a real-world EV range between 30 and 35 miles for the 408 plug-in hybrid. For those that drive short distances and can take advantage of the lower costs of electric driving, then the PHEV does make sense. However, if you are driving long distances on a regular basis, it will certainly be worth considering a pure electric car instead. The latest generation of battery-electric vehicles (BEVs) have a zero-emission electric range between 200 miles to 300 miles. In some cases, even more!

We encourage driving a PHEV on the e-mode, to leverage the benefits of driving a plug-in hybrid. Apart from zero-tailpipe emissions, when driven on the electric mode, a PHEV offers the opportunity to lower the cost of motoring. Depending on where an EV is charged, the driving cost per mile can be below 10 pence i.e. far lower than using a conventional petrol or diesel vehicle.

We recommend charging at home and overnight, when the electricity tariff prices are lower. We also encourage taking advantage of on-site solar generation and battery storage, to further reduce the cost of charging and lowering emissions.

The Peugeot PHEV does not offer DC charging capability. Most plug-in hybrids do not, given the smaller size of the onboard EV battery. The plug-in hybrid incorporates a 3.7 kW AC onboard charger as standard, with an option to upgrade to a 7.4 kW AC onboard charger.

Charging via a smart residential EV charger like easee, the 3.7 kW AC option can achieve full charge in 3 hours and 25 minutes. With the upgraded 7.4 kW AC onboard charger, the EV can be fully charger in 1 hour and 40 minutes. We at e-zoomed recommend upgrading to the 7.4 kW AC onboard charger, as it will also help reduce the charging time at public charging stations.

Though the PHEV can be charged via a standard 3-PIN domestic plug, we at e-zoomed discourage the use of a domestic plug for charging an electric car. Those still keen to use one, the EV will take up to 5 hours and 30 minutes to achieve a full charge.

Though the interior of the EV is not as radical as the exterior, the PHEV does offer practicality and style. Given the length of the EV (4.6 metres), there is ample legroom for rear seat passengers. However, due to the Fastback roofline, the headroom can be tight for taller adults. The electric car offers a boot size up to 471 litres and a hands-free smart electric tailgate.

In terms of technology, the PHEV incorporates the latest-generation PEUGEOT i-Cockpit with a 10” digital display and 10” HD central touch-screen. The manufacturer offers a host of driver assistance aids, either as standard or as an option. Some of these include: active safety brake system, lane keeping assist, long range blind spot detection, adaptive cruise control, lane positioning assist, night vision and more!

The plug-in electric car is available in two drivetrain options: HYBRID 180 e-EAT8 and HYBRID 225 e-EAT8. The HYBRID 180 e-EAT8 pairs a 1.6-litre PureTech 150 hp petrol engine with an electric motor (81 kW), powered by an onboard EV battery. The HYBRID 225 e-EAT8 pairs the PureTech 179 hp with the 81 kW electric motor.

In terms of performance, the front-wheel drive HYBRID 180 e-EAT8 delivers 0-62 mph in 8.1 seconds, with a 140 mph top speed (maximum power: 180 hp/ torque: 360 Nm). The HYBRID 225 e-EAT8 delivers 0-62 mph in 7.8 seconds, with a 145 mph top speed (maximum power: 225 hp/ torque: 360 Nm).

The electric car also benefits from instant torque. The EV incorporates 3 driving modes: Hybrid, Electric and Sport. We recommend driving as often as possible on the electric mode. The PHEV also incorporates regenerative braking to increase the efficiency and electric range.

Company-car drivers can also take advantage of the lower Benefit-in-Kind (BiK-8%) tax rate for the PHEV. Bottom-line, electric driving is good for the environment and the wallet. You can lease electric vehicles (EVs) via e-zoomed at very competitive prices!
