A110 HE2HP project proceeds! If the drive on the Bugatti circuit of Le Mans, scheduled for June, and announced on the occasion of our discovery at the Dieppe workshop in March, has not yet finally taken place, the development of the project is really effective … and above all everything that we could have glimpsed its dynamic claims!
Chance does things well, but this second installment of the Alpine A110 HE2HP project follow-up closely follows the unveiling of the all-new 100% electric Alpine A110 E-ternity. A car that was able to do a few laps on the Paul Ricard circuit during the French F1 Grand Prix.
Recall that if Alpine has officially announced its 100% electric future (and this prototype launches the trailer), the Technomap team is well on its way to an Alpine A110 hybrid, ethanol and four-wheel drive, which more so it is. Between desire for innovation and passion for motorsport, the car we are interested in retains the ambition of an experimental prototype, even if the alternative to all-electric would undoubtedly appeal to many customers of the current thermal A110… on loan!
Yes auto était tout juste capable de rouler en mode dégradé en électrique, en thermique et en hybride en mars, elle est depuis suffisamment développée et fiabilisée pour s’éloigner de son atelier de Dieppe, presque voisine de l’usine historique de la brand. The first real driving of the car took place among the partners, on the well-known Linas-Montlhéry racetrack (91), a place of so much automotive history, of records, and today at the heart of the innovation of the car of tomorrow.
Our second car discovery then followed this busy car day.
Alpine A110 hybrid ethanol: Extreme laboratory in Dieppoise
Since our latest discovery, the Alpine A110 (S) production has seen the arrival of an Aero Pack and Michelin Pilot Sport Cup 2 semi-slick tires as supplements … Furthermore, the Pilot Sport 4 production of the prototype has been quickly “updated” “! We also notice a modification of the admission, 330 mm diameter discs on the cup, ventilated and grooved developed by MP Rezeau associated with CL-Brakes pads with a high coefficient of friction…. some hiding places and dishes for decoration; also and above all the battery completely immersed under the center console! The A110 HE2HP is therefore more “finished”.
A small parenthesis to echo this A110 HE2HP project: the memory of Peugeot Sport’s 308 R-Hybrid project … A 4-wheel drive hybrid 308 that develops up to 500 HP from a standstill, that yours has really had the opportunity to observe between the Paul-Ricard circuit, the Val de Vienne and the Linas-Montlhéry (again him). A very advanced prototype, sometimes accompanied by the Showcar version, which came very close to mass production. If you see a dull gray A110 during an upcoming circuit event, think about Technomap! It should be noted that the R-Hybrid was in a sense the trailer of the 508 PSE, a standard high-performance hybrid – it is true that it is much more reasoned -; the concept in particular was presented in the context of an event at Le Mans… leaving a first clue on the place of the press tests of the 508 PSE: the Bugatti circuit of Le Mans! Also placed for the challenge of our A110 HE2HP… everything overlaps.
Very privileged first laps as a passenger!
After the partner circuit session, we were honored with an open road trip. But the installation of Sparco harnesses in the Technomap workshop does not suggest such a pleasant and relaxed Sunday walk. The noise of the cylindrical gears of the front electric gearbox leaves no more doubts about the philosophy of the car: there will be sport! Also, even in all-electric driving, don’t believe this A110 will lose noise and soul, at least on the inside. Alexandre Dutot, Technomap technical manager, then behind the wheel, then reveals other secrets of the car.
“The car was really designed for Le Mans. The first rises to 100 km / h; the sixth 220. Not enough to highlight a firm start. Without the support of the electric, the thermal is very empty ”. We are in fact far from the docility and versatility of the A110 standard. At start-up, the thermal is very temperamental! It vibrates, sobs, and here we are shaken as dissatisfied with its cold start. Recall that the sequential box has imposed the installation of a clutch pedal, which is only used to launch the car … given the length of the first, it is not an easy task! Below 3000 rpm, the 100% thermal mode shows a very dull 1.8 TCe; the support of the electric in hybrid mode is therefore largely advantageous to smooth everything and circulate more harmoniously within Dieppe.
Alexandre regularly plays with the two maps “Soft” and “Sport” of the internal combustion engine and the electric motor, which can be adjusted independently. We count 350 HP and 350 Nm in “soft” thermal, 400 HP and 400 Nm in “sport” thermal. As on any hybrid, the electric will always compensate for the drop in thermal at low revs with its spontaneity and will try in Soft mode to save itself once the turbo starts or even not to wear out unnecessarily at low load, when it sees the its full performance in sports mapping. Also note that the electric does not save the presence of the 12V battery, in the absence of DC / DC converters inside the vehicle.
A 600 hp A110? Supercar shows!
We were able to glimpse the performance of the car in its optimal configuration, even if the internal combustion engine perhaps did not have its full displacement: “it could only have 500 HP today! jokes Alessandro. However, under full load, we have the feeling that our field of vision has shrunk, to see us catapulted into a certain violence! Potentially similar to what you feel when starting a Tesla from a standstill, or when driving in thermal supercars like a Porsche 911 Turbo S (992) or Mclaren 720S … Ironically, Technomap was aiming for 1322 kg as a target weight for its little treasure: the exact value of the 720S, for 720 hp, if you follow it right. But the teams did even better, with 1263 kg. Enough to find the 911 very heavy at 1640 kg (for 650 hp).
No apparent concern about unloading the power to the ground with these four-wheel drive, but it seems necessary to keep the car !! Yes “steer”! The circuit settings seemed to show that it read a lot of the road and its imperfections. It seems that it is looking for its way, but with great efficiency. The thrust strongly anticipates the gear changes in hybrid mode and full power: even our experienced driver, passionate about motorsport, is almost always a little intimidated! Alexandre then confided to us that the car has rolled up a lot of the rear in 100% thermal (therefore in propulsion), even more than the standard one. The car has since calmed down and is logically more serene in Hybrid mode and therefore all-wheel drive. Note that the car benefits from a self-locking variable preload. In addition, the P2S coilover suspension was set very solid, like an A110 GT4 on the track, during the first few laps. The compromise found today is somewhere between a “standard” A110 and a more track-oriented A110S. Urban bumps don’t scare him.
In any case, with the semi-slicks, harnessed to the original Sabelt seats, the noise of the front reducer, the jolts in the gear changes of the sequential gearbox and the engine without soundproofing create a unique atmosphere on this winding road. around Dieppe! What to believe in the passenger of a rally super A110 RGT… with practically double the power. Incredible.
Everything is still not perfect and still deserves development time. The engine mounts showed some fragility in the face of the vibratory stresses that the car has: a repair was then carried out during the lunch break. Nothing is complex, everything is possible, just enough to feel closer to a motorsports team during a circuit or a rally event than a normal Renault workshop! In addition, the regeneration is developed via a brake pressure sensor, which does not yet give full transparency and satisfaction. The same problem we have in series on electric and hybrid cars but which will not be allowed for the A110 HE2HP track challenge! For the moment the known regenerative braking solutions in series, of the “One Pedal” type and via pedal position sensor (regenerative then mechanical braking) are excluded.
There was also talk of poor heat output: due to a slightly insufficient turbo pressure, the power was more like about 350 hp which, in the thermal alone, gave the impression of a lack of resources! The Technomap team would have recovered the expected power of 400 hp (and 400 Nm) and would aim for 450 thermal hp.
The cumulative power in Hybrid and “soft” thermal is 554.7 HP and 728.6 Nm … proof of the newfound health !! 398.5 hp pure combustion, Sport mapping.
Nervous of the war of any electrified car, even the charging time is still not optimal: the team hopes to be able to reach 25 kW of power but is aiming for 10 kW for the moment, waiting to find common ground between Technomap and specific supplier . The charging time is therefore 1h30 for the moment; when the thermal is satisfied with a tank of only 25 L! Electric autonomy is not yet a known fact and thermal autonomy … not really a relevant topic given the vocation of the car. Only our two tadpoles seem to have started the tank well!
A dynamic and mouth-watering first ride …
These few hours spent with the car did not disappoint the high expectations on the car’s performance! Such a moment of exchange with the Technomap team showed another very privileged day: a big thank you to Christophe, David, Nicolas, Alexandre and all the team for the warm welcome and these passionate discussions about the car, without rejecting all the possibilities of evolution and revolution. Because the car hasn’t finished surprising us …
See you at the beginning of the school year for an evolution on the circuit? Keep on…
