Alpine A110 HE2HP: the electrified Alpine is here… and with more than 550 hp!

The A110 HE2HP project is progressing! If the drive on the Bugatti circuit at Le Mans, planned for June, and announced during our discovery of the workshop in Dieppe in March, has not finally happened, the development of the project is really effective … all that we could have seen the dynamic pretensions!

Chance did a good job, but this second stage of the follow-up to the Alpine A110 HE2HP project closely follows the presentation of the very fresh 100% electric Alpine A110 E-ternity. A car that did a few laps of the Paul Ricard circuit during the F1 Grand-Prix de France.

Alpine A110 E-ternity – AlpineCars

As a reminder, when Alpine officially announced its 100% electric future (and this prototype launched in the trailer), the Technomap team was close to an Alpine A110 hybrid, ethanol and four-wheel drive, which is more yet. Between a desire for innovation and a passion for motorsport, the car that interests us retains the ambition of an experimental prototype, although the all-electric alternative will undoubtedly attract many customers to now thermal A110… on borrowed time!

If the car was only able to drive the degraded mode of electric, thermal and hybrid in March, it will be developed enough and become reliable to move from its workshop in Dieppe, almost next to the historical Mark factory. The first real driving of the car was held indoors with partners, at the famous Autodrome of Linas-Montlhéry (91), place of a lot of car history, records, and now at the heart of tomorrow’s car innovation.
Our second car discovery followed this terrible day for the car.

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 in prototype quickly “upgraded” ! We also noticed a change in the admission, discs of 330 mm diameter in the bowl, ventilated and grooved developed by MP Rezeau related to CL-Brakes pads with a raised coefficient of friction…. some caches and plates for decoration; also and best of all the battery is completely sunk under the central console! So the A110 HE2HP is more “finished”.

A small parenthesis echoing this A110 HE2HP project: the memory of the 308 R-Hybrid project from Peugeot Sport… A 308 hybrid 4-wheel drive that develops up to 500 hp from a standing start, which you really have the opportunity to observe between the Paul-Ricard circuit, the Val de Vienne, and Linas-Montlhéry (he again). A very advanced prototype, sometimes accompanied by the Showcar version, which is about to go into series production. If at a future circuit event, you see a matt gray A110, think Technomap! Note that the R-Hybrid in a way is the trailer for the 508 PSE, a standard high-performance hybrid – it is true that it is more argued -; the concept was presented especially within the framework of an event at Le Mans… leaving a first clue at the place of the press tests of the 508 PSE: the Bugatti circuit at Le Mans! Also an area for challenge with our A110 HE2HP… everything overlaps.

Very privileged first laps as a passenger!

After the partner circuit session, we were honored to drive on the open road. But the installation of Sparco harnesses in the Technomap workshop does not suggest such a nice little leisurely Sunday stroll. The noise of the spur gears of the front electric reducer leaves no doubt about the car’s philosophy: there is sport! Also, even with all the electric drive, don’t believe that this A110 will lose the noise and soul, inside at least. Alexandre Dutot, technical manager of Technomap, then the wheel, then detail other secrets of the car.

“The car was really designed for Le Mans. The first reaches 100 km/h; the sixth 220. Not enough to promote the stopped start. Without the electrical support, the thermal is very empty”. In fact, we are far from the docility and efficiency of the standard A110. To begin with, the thermal is capricious! It vibrates, hiccups, and here we are shaken as if it is not satisfied with its cold start. We remember that the series box imposes the installation of a clutch pedal, which is used only to launch the car … due to the length of the first, it is not an easy task! Below 3000 rpm, the 100% thermal mode actually shows a very muted 1.8 TCe; the electric support of the hybrid mode is the most useful to streamline everything, and circulate more harmoniously within Dieppe.

Alexandre always plays with both “Soft” and “Sport” maps 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 with any hybrid, the electric always makes it possible to compensate the thermal slippage in short changes by its spontaneity and find the Soft mode to save itself once the turbo starts or even does not run out not required at low load. , when he sees in action his full performance in sport mapping. Note also that the electricity does not save the presence of the 12V battery, without the DC / DC converters inside the car.

A 600 hp A110? Supercar shows!

We got a glimpse of the car’s performance in its best configuration, although the combustion engine may not have its full capacity: “maybe only 500 hp now! jokes Alexander. Even yet, at full load, we have the feeling that our field of vision is reduced, to see ourselves falling into a certain violence! Possibly similar to what one would feel when starting the a Tesla from a standstill, or when driving thermal supercars such as a Porsche 911 Turbo S (992) or a Mclaren 720S … Surprisingly, Technomap points to 1322 kg as a target weight for his little wealth: the exact amount of the 720S, for 720 hp, if you follow the right. But the teams did even better, with 1263 kg. Enough to find the 911 very heavy with 1640 kg (for 650 hp).

There is no apparent concern to transmit the power to the ground with these four-wheel drives, but it seems necessary to hold the car!! It “drives”! The circuit settings seem to indicate that he read the road well, and its imperfections. He seems to be finding his way, but with great efficiency. The drive strongly anticipates gear changes in hybrid mode and full power: even our experienced driver, motorsport enthusiast, is almost always scared! Alexandre told us that the car rolls a lot in the rear at 100% thermal (hence the propulsion), more than the series. The vehicle has since been calmed down and it is more logically more peaceful in Hybrid mode and therefore four-wheel drive. Note that the car benefits from a self-locking variable preload. Also, the coilover suspension from the P2S was set firmly, like an A110 GT4 on the track, during the first runs. The compromise found today is somewhere between a “standard” A110 and a more track-oriented A110S. Urban speed bumps do not scare him.

In any case, with the semi-slicks, harnessed to the original Sabelt seat, the noise of the front reduction gear, the jolts of the gear changes in the sequential gearbox and the engine without soundproofing show a unique atmosphere of on this winding little road. Around Dieppe! What would the passenger believe in a super A110 RGT in the rally… with almost twice the power. Unbelievable.

Not everything is perfect, and it still deserves time to improve. The engine supports showed a slight weakness in front of the vibratory stresses present in the car: a repair was made during lunch. Nothing complicated, everything is possible, enough to feel closer to a motorsport team during a circuit or rally event than a normal Renault workshop! Also, the change is made through a brake pressure sensor, which does not yet provide full transparency and satisfaction. The same problem we have with the series of electric and hybrid cars but not allowed for the A110 HE2HP track challenge! The well-known regenerative braking solutions of the series, the “One Pedal” type and the pedal position sensor (regenerative then mechanical braking) are currently no longer available.

We are also talking about the lack of thermal performance: due to the slightly insufficient pressure of the turbo, the power is like almost 350 hp which, thermally alone, gives the impression of a lack of resources! The Technomap team would recover the expected power of 400 hp (and 400 Nm) and aim for 450 hp thermal.

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

The battle nerve of any electrified car, the recharge time is also not optimal: the team hopes to reach 25 kW of power but the moment caps at 10 kW, while waiting to find the common basis between Technomap and supplier specifications. The instant recharging time for the moment is 1h30; when the thermal is satisfied in a small tank of only 25 L! Electric autonomy is not yet a known fact and thermal autonomy… is not really a topic of importance given the automotive vocation. Our two little laps seemed to start well in the tank!

A dynamic and mouth-watering first ride…

These few hours spent in the car did not disappoint the high expectations of the car’s performance! Such an opportunity to exchange with the Technomap team marks another very privileged day: a big thank you to Christophe, David, Nicolas, Alexandre and the whole team for their warm welcome, and these passionate discussions of the car, without denying all the possibilities of evolution. and revolution. Because the car was not finished yet we were surprised…
