26 times 0–200: Porsche Taycan staying power is tested

Published

on

Numerous hot laps around a circuit seem to be a breeze for the first fully electric sports car from Zuffenhausen.

In an initial test, a pre-series version of the 440 kW (600 PS) all-wheel drive car accelerated from 0–200 km/h 26 times in succession. The Sprint Challenge was held at an airfield in Lahr in southern Baden. Average acceleration times documented on the “Fully Charged” YouTube channel were just under ten seconds. The difference between the fastest and the slowest attempts was just 0.8 seconds. The test runs were carried out in both directions on the airport’s taxiway. The entire strip, about 2.3 kilometres long, was used during the tests. The outside temperature was 28 degrees Celsius.

The Taycan is the first all-electric sports car from Porsche.

A full range of technical innovations in the Taycan guarantees breathtaking acceleration figures, traction power typical of a sports car and a superior, permanently-available power output.

  • The two powerful electric motors at the front and rear axles are the so-called permanently excited synchronous motors (PSM). They feature a rotor with high-grade permanent magnets that generate a natural magnetic field. As a result, the rotor moves in sync with the magnetic rotating field of the stator, hence the name PSM. A pulse inverter specifies the frequency of the rotating field in the stator, therefore determining rotor speed. The design, function and excellent thermal behaviour of permanently excited synchronous motors allow them to deliver the high performance typical of Porsche.
  • A special feature of the Taycan’s electric motors is the so-called hairpin winding, in which the solenoid coils of the stator consist of rectangular rather than round wires. The wires are bent, and before they are inserted into the stator’s laminated core their shape looks like a hairpin – hence the name “hairpin”. The open ends are welded together using a laser beam. Hairpin technology makes it possible to pack wires in a more condensed way and therefore integrate more copper into the stator. This increases power output and torque at the same level of volume. Another important advantage for a high-performance car like the Taycan is that a hairpin stator can be cooled considerably more efficiently.
  • The Taycan is the first production vehicle with a system voltage of 800 voltsrather than the normal 400 volts for electric cars. Among other things, this delivers continuous high power and charging capacities to enable both fast driving and fast loading,  while also reducing the weight of the high-voltage cabling.
  • In combination with the drive train concept (PSM and 800-volt technology), thermal management ensures a high reproducibility for when power is demanded. The cooling system is tailored to the needs of the individual vehicle and enables the performance, which is typical of a sports car, to be achieved multiple times in succession when required. Porsche has achieved a wide spread between performance and range. In winter, intelligent thermal management also enables efficient and demand-oriented heating functions.

The Taycan has a top speed of over 250 km/h. It accelerates from 0–100 km/h in significantly less than 3.5 seconds and its lithium-ion battery has a gross capacity of around 90 kWh. The Taycan will be presented in September and launched onto the market at the end of the year.

The test track: Lahr airport

Opened in 1913 and intended as a Zeppelin airfield, Lahr was used after the Second World War as a military airfield, initially by French troops and from 1967 by Canadian NATO troops. ADAC Südbaden (a regional division of a German automotive association) has been using the facility for motorsports events ever since the latter withdrew in 1994. The Regio-Ring, as it is known, held Formula and touring car races between 1996 and 1998, sometimes drawing crowds of over 30,000 spectators.

Today the airport is situated directly off the A5 motorway from Karlsruhe to Basel and used for business and freight flights, as well as by the automotive industry for test drives and measuring runs.

First ever V12 Ferrari with a retractable hardtop.

Published

on

2020 Ferrari 812 GTS Rear top view

The new 2020 Ferrari 812 GTS is the spider version of the Ferrari 812 Superfast, from which it takes both its specifications and performance.

Firsts

Not only is the new 2020 Ferrari 812 GTS Spider the first ever V12 Ferrari with a retractable hardtop, Ferrai claims it is also the first ‘production series’ front mount V12 convertible since the classic Ferrari 365 GTS4 Daytona’s of 1969. This all assumes you do not count the 448 examples of the 550 Barchetta Pininfarina produced in 2000, the 559 examples of the Superamerica in 2005 or the 80 examples of the SA Aperta in 2010 as production series.

Ferrari’s V12 spider history

The Ferrari V12 spider history features some iconic models which began in 1948 with the 166 MM, a competition GT that won the two most prestigious endurance races in the world in 1949: the Mille Miglia and the 24 Hours of Le Mans. The last in that long lineage was the 1969 365 GTS4, also known as the Daytona Spider because of Ferrari’s legendary victory in the 1967 24 Hours of Daytona when two works 330 P4s and the NART-entered 412 P took the chequered flag side by side to occupy the top three places.

Retractable hardtop features

The retractable hard top opens in 14 seconds at speeds of up to 45 km/h and does not impede upon the interior dimensions, maintaining the same cabin space as the 812 Superfast. The rear electric screen acts as a wind breaker making the car comfortable with the top down. With the roof closed, the rear electric screen can be left open so occupants can still enjoy the naturally aspirated V12’s sound.

There was huge focus on minimising both turbulence inside the cabin and aerodynamic noise to ensure occupants could converse undisturbed even at high speeds. As with the LaFerrari Aperta, two small L-shaped flaps on the upper corners of the windscreen generate a coherent concentrated vortex that creates outwash in the velocity field immediately above the rear screen, thereby avoiding excess pressure behind the occupants’ heads.

Exterior and aerodynamics

Aerodynamically, the 812 GTS posed two main challenges for the Ferrari designers. How to guarantee the same performance as the 812 coupé version with the top up and, at the same time, ensure maximum passenger comfort with the roof down.

In terms of aerodynamic performance, the retractable hard top and its stowage compartment, required that the rear of the car be modified. Thanks to meticulous re-sculpting of the tonneau cover surfaces and, most importantly, the integration of a triplane wing into rear diffuser to create efficient suction (and thus downforce) from the underbody, the aerodynamic engineers were able to compensate for the downforce lost by the removal of the 812 Superfast’s rear wheelarch bypass duct, (the air intake of which was behind the quarterlight on the 812 Superfast).

Drag, on the other hand, was cut by using the air vents on top of the rear flank to efficiently channel excess pressure build up out of the wheel well.

Engine and performance

The 812 GTS is the spider version of the 812 Superfast, from which it takes both its specifications and performance, most notably the V12 engine which, thanks to its ability to unleash a massive 800 cv at 8500 rpm, is the most powerful engine in its class! 718 Nm of torque guarantees impressive acceleration virtually on a par with that of the 812 Superfast while the 8900 rpm rev limit means that sporty driving is undiminished.

As on the 812 Superfast, these performance levels were achieved in part by optimising the engine design and in part by innovations, such as the use of a 350 bar direct injection system, and the control system for the variable geometry inlet tracts, developed on naturally-aspirated F1 engines. These systems allowed the increase in displacement from 6.2 to 6.5 litres to be exploited to maximise power output whilst retaining excellent pick up even at low revs.

Overall, performance levels are very close to those of the 812 Superfast, with 0-100 km/h acceleration still under 3 seconds and 0-200 km/h in just 8,3 seconds. The Ferrari 812 GTS’s maximum speed is the same as the berlinetta’s at 340 km/h.

Exhaust changes for the convertable

Due to the open air nature of the 812 GTS drivers are more able to hear the V12’s characteristics and so the geometry of the exhaust system was evolved to increase and balance the sound from the engine and tailpipes. Exhaust-wise prevalence was given to combustion order harmonics by modifying the geometry of the centre extension pipes. All the pipes in the 6-in-1 exhaust manifold to the monolithic catalytic converter are of equal-length and this optimises the sound by giving predominance to the first order combustion harmonics.

Ferrari 812 GTS Price

Sale date and price are yet to be announced however the price is expected to start northwards of US$335,275.

First hybrid Lamborghini – The limited edition Sián

Published

on

The new hybrid is the most powerful Lamborghini ever produced and harnesses the past, the present and the future in one.

Why the name Sián?

Sián means‘ flash or lightning’ in the Italian Bolognese dialect, therefore Lamborghini chose this to mark their first electric application in a Lamborghini production car.

New energy accumulation technology

A 48 volt e-motor, delivering 34 hp, has been incorporated into the gearbox to provide immediate response and improved performance: the first time in any low-voltage hybrid that a direct connection has been made between electric motor and wheels. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power. The energy accumulation technology is a world first. Rather than a lithium-ion battery the Sián innovates supercapacitor application: a technology pioneered originally in the Lamborghini Aventador but dramatically developed to store ten times the power. It is three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power. Located in the bulkhead between cockpit and engine it ensures perfect weight distribution. The electric system with the supercapacitor and e-motor weighs only 34 kg, thus it delivers a remarkable weight-to-power ratio of 1.0 kg/hp. Symmetric power flow ensures the same efficiency in both charging and discharging cycles: the most lightweight and efficient hybrid solution.

Sián’s power and top speed

This e-motor combines with a V12 engine, which incorporates titanium intake valves and is uprated to 785 hp (577 kW) at 8,500 rpm: the highest output ever from a Lamborghini power plant. Combined with the additional 34 hp from the hybrid system, the Sián delivers a total of 819 hp (602 kW), and still produces the distinctly emotive resonance demanded from a Lamborghini engine. The Sián’s power-to-weight ratio is better than that of the Aventador SVJ, achieved through extensive use of lightweight materials. The Sián reaches a top speed of over 350 km/h.

The innovative system also delivers instant acceleration in low gears, with improved traction force provided by the combination of V12 engine and hybrid system. This makes the Sián the fastest accelerating Lamborghini ever, achieving 0 to 100 km/h in less than 2.8 seconds. The improvement in elasticity maneuvers is even more evident. Traction force is improved by up to 10% in third gear and the 30 to 60 km/h acceleration time is improved by 0.2 seconds compared to the Aventador SVJ. In higher gears and lower speeds the electric motor increases traction force by up to 20%, reducing the 70 to 120 km/h acceleration by 1.2 seconds compared to the Aventador SVJ.

Regenerative braking

The Lamborghini Sián incorporates a highly advanced regenerative braking system, especially developed by Lamborghini. Thanks to the symmetric behavior of the supercapacitor, which contrary to normal Li-Ion batteries can be charged and discharged with the same power, the Sián’s energy storage system is fully charged every time the vehicle brakes. The energy stored is an instantly-available power boost, allowing the driver to draw immediately on increased torque when accelerating away, up to 130 km/h when the e-motor automatically disconnects, improving the elasticity maneuvers and making it more than 10% faster than a car without this system.

Exterior design: bringing the Countach past into the Sián future.

Lamborghini took futuristic inspiration from the Countach, the Gandini line is evident in its profile, while the silhouette introduces new features such as the characteristic aero wings, giving the Sián an unmistakable profile. The iconic Lamborghini ‘Y’ shape can be seen in the NACA air inlets on the doors, glass elements are included in the engine cover, and the diagonal line features in the front hood, as in the Countach. In its long, honed, sculptured contours, like the Countach, the Sián’s design is pure and uncluttered. The low front with integrated carbon fiber splitter is dominated by the ‘Y’-shape headlights, used for the first time to reflect the signature design of the night lights, originally designed for the Lamborghini Terzo Millennio. The extreme and strong rear of the car incorporates the hexagonal design so linked with Lamborghini, including six hexagonal tail lights inspired by the Countach. The rear wing is integrated within the profile, and extends out only during the driving to enhance the performance. In the roof, the ‘Periscopio’ tunnel that originally incorporated a rear mirror in the Countach, adds a bold feature that links with the slats of the rear engine cover and important elements contributing to the car’s aerodynamic efficiency.

Limited Edition

The Sián will be limited to 63 examples only, with each of the 63 masterpieces to be individually styled by each owner through Lamborghini Centro Stile in conjunction with Lamborghini Ad Personam. The specifically designed configuration for the car shown at the IAA in Frankfurt in Verde Gea (green) with details in Oro Electrum (electric gold) is visualizing the electrified Lamborghini of the future and underlining Lamborghini’s leadership in terms constantly striving for the highest execution of color and materials. It is painted with a very precious multilayer color containing golden flakes and golden crystals, perfectly complementing the internal design. The interior is executed with aniline leather in ‘Terra di Sant’Agata Bolognese’, specifically developed and  implementing 3D printed parts for the first time in production.

“The fastest Lamborghini must be a visual and symphonic feast, as remarkable to those who see it pass by as those privileged to drive it, “says Mitja Borkert, Head of Design at Automobili Lamborghini. “It takes inspiration from the Countach, but the Sián is a futuristic icon, not retrospective. Exclusivity is enhanced by total Ad Personam personalization that every one of the 63 Sián owners has the privilege of creating, in conjunction with me and the Centro Stile team: 63 individuals worldwide will own not only the fastest, but a unique Lamborghini.”
