Driving 100% electric is good, but being able to count on a heat engine to go on weekends is better! For those who are worried about a breakdown, Peugeot has just launched the 508 rechargeable hybrid. What is it worth? To find out, we set it against one of the benchmarks in the category, the BMW 330e. Which one uses this technology best? In fact, we will especially highlight two very particular philosophies.
While waiting for 100% electric vehicles to have sufficient autonomy and suitable recharging infrastructures, the rechargeable hybrid represents for some the ideal solution. This technology no longer benefits from government aid, but it nevertheless allows us to escape the ecological penalty thanks to the advantageous approved consumption. In addition, the beautiful mechanical approval makes them good road, popular with professionals. But individuals will also find it interesting, to carry out their daily journeys in 100% electric, without giving up going on vacation or WE thanks to the heat engine.
One car for dual use. With the launch of the very recent 508 plug-in hybrid known as PHEV, we can see that Peugeot is more than ever in a premium hunting dynamic: 51,250 euros for this 508 PHEV full option, this is the entry-level price of this BMW 330e (from 51,800 euros). The Peugeot stops where the BMW starts. However, equipment and finishes will not be on the agenda. We suspect that a premium vehicle will generally be better designed than a generalist. We will simply determine which is the best plug-in hybrid.
A much more efficient BMW
First point of comparison: same technology for two solutions, with Peugeot's side a four-cylinder 1.6 liter turbo with 180 hp supported by an electric motor for a combined power of 225 hp in traction mode. BMW has seen more with a 2.0-liter four-cylinder with a double-stage turbo developing 184 hp. This power is combined with that of the electric motor for a total of 292 hp in drive mode.
In terms of lap times, the BMW largely takes the advantage with a 0 to 100 km / h shipped in 5.9 s while the Peugeot requires 7.9 s in the same financial year. We can already see that the two models offer a slightly different driving experience with more dynamic typing for the 330th, which is the only one to offer a specially dedicated “Sport” button (in parallel with the menu for selecting the different modes of conduct). No doubt, BMW's brand philosophy is well respected. It is also found in terms of precision of the controls as the driving position. Mechanically, it works so hard that we come to the point of wondering if it's really well rational to offer such performance to a plug-in hybrid vehicle!
A much more efficient BMW
However, pure performance will not be decisive here. Or at least today we're going to focus on energy performance. And therefore it is the BMW, more powerful, which risks being disadvantaged. On paper, the 508 starts with 52 km of 100% electric autonomy thanks to its 11.8 kWh battery while the 330th announces 60 km with its 12 kWh battery.
But in practice, we only managed to browse 32 kilometers in 100% electric with the French before it turns into a simple hybrid, against 50 kilometers behind the wheel of the German ! The “announced / real autonomy” ratio is much better. Difficult to find better simply in terms of autonomy in plug-in hybrids!
In terms of recharging, the times are equivalent : around 6:30 on a 220-volt household outlet and 1 and a half hours on a wallbox. The batteries only impact one of the two models in terms of boot space: the Peugeot is doing perfectly with a preserved volume of 487 liters compared to the 375 liters of the BMW (or -105 liters) penalized by a battery integrated in the boot floor. Note also that it is the only one of the two to be offered in both sedan and station wagon! For some, it will make a difference.
removed weight gain, there are about 300 kilos of overweight on both sides but a clear advantage to the Peugeot with 1.720 kg against 1.815 kg for the BMW. Result, with more weight on the scale and a larger heat engine, the 330th turns out to be more fuel efficient. Approved at 1.9 l / 100 km (against 1.7 l / 100 km on average for the Peugeot), the consumption observed is around 8 liters / 100 km once its batteries are discharged. This corresponds to around 1 l / 100 km more on average than the 508.
