Discovery – Alpine A110 HE2HP: the electrified Alpine already exists… and it has more than 550 HP!

Discovery - Alpine A110 HE2HP: the electrified Alpine already exists... and it has more than 550 HP!

The A110 HE2HP project moves forward! If the driving on the Bugatti circuit in Le Mans, scheduled for June, and announced at the time of our discovery in the Dieppe workshop in March, has not finally taken place yet, the development of the project is indeed effective… and on top of that All we have could have glimpsed its dynamic pretensions!

Chance gets it right, but this second episode of the continuation of the Alpine A110 HE2HP project closely follows the introduction of the very 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.

Alpine A110 E-ternity – AlpineCars

As a reminder, if Alpine has officially announced its 100% electric future (and this prototype launches the trailer), the Technomap team is on its way to an Alpine A110 hybrid, ethanol and four-wheel drive, which is more. Between the desire to innovate and the passion for motorsport, the car we are interested in retains the ambition of an experimental prototype, even if the alternative to the fully electric one would certainly attract many customers of the current thermal A110… on borrowed time!

If the car could barely be driven in degraded electric, thermal and hybrid mode in March, since then it has been sufficiently developed and reliable enough to move away from its workshop in Dieppe, almost next door to the historic Marque factory. The first real driving of the car took place in the sphere of the partners, at the well-known Autodromo de Linas-Montlhéry (91), a place of so much automotive history, of records, and today at the heart of the innovation of tomorrow’s car.
Our second car discovery followed this car intensive day.

Since our last discovery, the production Alpine A110(S) has seen the arrival of an Aero Pack and Michelin Pilot Sport Cup 2 semi-slick tires as supplements… Also, the production Pilot Sport 4 prototype was quickly “updated”. ! We also noticed a modification of the intake, 330 mm diameter discs in the bowl, ventilated and grooved developed in MP Rezeau associated with CL-Brakes pads with a high coefficient of friction…. some hiding places and plates for decoration; also and above all the completely submerged battery under the center console! Therefore, the A110 HE2HP is more “finished”.

A small parenthesis that echoes this A110 HE2HP project: the memory of Peugeot Sport’s 308 R-Hybrid project… A 308 hybrid 4×4 that develops up to 500 CV from standstill, which yours truly had the opportunity to observe on the track Paul-Ricard, the Val de Vienne and Linas-Montlhéry (him again). A very advanced prototype, sometimes accompanied by the Showcar version, which was very close to entering series production. If during an upcoming circuit event, you see a matte gray A110, think Technomap! Note that the R-Hybrid was in a way the trailer of the 508 PSE, a high-performance standard hybrid –it is true that it is much more reasoned–; the concept had been presented in particular within the framework of an event at Le Mans… leaving a first clue about the place of the press tests of the 508 PSE: the Bugatti circuit at Le Mans! Also a place for our A110 HE2HP challenge… it all overlaps.

Very privileged first laps as a passenger!

After the partner circuit session, we had the honor of driving on the open road. But the installation of the Sparco harnesses in the Technomap workshop does not suggest such a nice and relaxed Sunday ride. The noise of the spur gears of the front electric reducer leaves no more doubts about the car’s philosophy: there will be sport! Also, even in fully electric driving, don’t think this A110 will lose noise and soul, at least inside. Alexandre Dutot, technical director of Technomap, then at the wheel, then details other secrets of the car.

“The car was really designed for Le Mans. The first goes up to 100 km/h; the sixth 220. It is not enough to highlight a stopped start. Without the support of the electric company, the thermal one is very hollow”. Indeed, we are far from the docility and versatility of the standard A110. When starting, the thermal is very capricious! It vibrates, it hiccups, and here we are both shocked and dissatisfied with its cold start. We remember that the sequential box has imposed the installation of a clutch pedal, which is only used to start the car… given the length of the first one, it is not an easy task! Below 3000 rpm, the 100% thermal mode effectively shows a very quenched 1.8 TCe; The support of the electric ones in hybrid mode is then greatly beneficial to smooth everything out 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. Let’s count 350 hp and 350 Nm in “soft” thermal, 400 hp and 400 Nm in “sport” thermal. As in any hybrid, the electric one will always allow to compensate for the thermal drop at low revolutions with its spontaneity and will seek to save itself in Soft mode once the turbo has started or even not consume itself unnecessarily with little load. , when you will see all your sports mapping performance in action. 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 performances!

We got a glimpse of the car’s performance in its optimal configuration, even if the combustion engine was perhaps not at its full capacity: “it may only have 500 hp today! Alexander jokes. However, in full load, we have the feeling that our field of vision is reduced, of being catapulted into a certain violence! Potentially similar to what it might feel like to start a Tesla from a standstill, or drive insulated supercars like a Porsche 911 Turbo S (992) or Mclaren 720S… Ironically, Technomap was targeting 1,322kg as a target weight for their little treasure. : the exact value of the 720S, of 720 hp, if followed correctly. But the teams did even better, weighing in at 1,263kg. Enough to find the 911 very heavy with its 1640 kg (for 650 hp).

There are no apparent concerns about getting the power to the ground with these four wheel drive, but the car seems to have to be put up with! It is directed”! The circuit settings seemed to show that he was reading the road and its imperfections a lot. It seems to find its way, but with great efficiency. Thrust strongly anticipates gear changes in hybrid and full power mode: even our experienced driver with a passion for motorsports is almost always a bit intimidated! Alexandre then confided to us that the car rolled up the rear a lot in 100% thermal (therefore in propulsion), even more than the stock one. Since then, the car has calmed down and is logically more serene in hybrid mode and therefore four-wheel drive anyway. Note that the car benefits from self-locking variable preload. Also, the P2S coilover suspension sat very tight, like an A110 GT4 on the track, for the first few laps. The compromise found today is somewhere between a “standard” A110 and a more track-oriented A110S. Urban speed bumps don’t scare him.

In any case, with the semi-slicks, mated to the original Sabelt seats, the noise from the front gearbox, the jerky gear changes from the sequential gearbox and the unsounded engine show a unique atmosphere on this winding road. . around Dieppe! What to believe as a passenger in a super rally A110 RGT… with practically double the power. Incredible.

Not everything is perfect yet, and it still deserves development time. The engine mounts were a bit brittle from the vibratory stresses the car has: then a repair was made during the lunch break. Nothing is complex, everything is possible, enough to feel closer to a motorsport team during a circuit or a rally than in a normal Renault workshop! In addition, the regeneration takes place through a brake pressure sensor, which still does not provide full transparency and satisfaction. Same problem we have in the electric and hybrid car series but will not be allowed for the A110 HE2HP track challenge! The well-known regenerative braking solutions in series, of the “One Pedal” type and by pedal position sensor (regenerative braking then mechanical) are ruled out for the moment.

We were also talking about the lack of thermal performance: due to slightly insufficient turbo pressure, the power was around 350 hp, which, in thermal terms 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 point to 450 thermal hp.

The accumulated power in Hybrid and thermal “soft” is 554.7 CV and 728.6 Nm… proof of health recovered!! 398.5 CV in pure combustion, mapped Sport.

Nervous about the war of any electrified car, the recharging time is not yet optimal either: the team hopes to reach 25 kW of power but limits it to 10 kW for the moment, hoping to find common ground between Technomap and the provider. specs. The recharge time is then at the moment 1h30; when the thermal is satisfied with a small tank of only 25 L! The electric autonomy then is not yet a known fact and the thermal autonomy… is not really an important issue given the vocation of the automobile. Just our two little laps seem to have started the tank well!

A dynamic and delicious first trip…

These few hours spent with the car did not disappoint the high expectations of the car’s performance! That moment of exchange with the Technomap team showed another very privileged day: many thanks to Christophe, David, Nicolas, Alexandre and the whole team for their warm welcome and these passionate discussions about the car, without rejecting all the possibilities of evolution. and revolution. Because the car has not finished surprising us…

Shall we meet at the beginning of the school year for an evolution on the circuit? To follow…
