2020 Porsche 935 'Martini'

 

"One of the rarest Porsche's in the world..."

 

     

Of only 77 made for Porsche's top customers, it is aimed to blend modern, unrelenting performance with styling inspired by an icon of Porsche's rich motorsport heritage, the Porsche 935 "Martini" is based on the 991.2-generation 911 GT2 RS Clubsport.

This latest version of the Porsche 935 was launched in the fall of 2019 at Laguna Seca Raceway in California as part of Rennsport VI to commemorate Porsche's 70th anniversary.

A factory driver unleashed it for several high-speed demonstration laps, much to the pleasure of the spectators.

"This fantastic automobile is a birthday present from Porsche Motorsport to fans all over the world," according to Porsche's Dr. Frank-Steffen Walliser. Engineers and designers didn't have to follow the customary standards because the automobile wasn't homologated, and so had more latitude in the development.”

Spectacular is an understatement; despite a dry weight of 1,390 kg, the new 935/19 is capable of a top speed of 340 km/h and can accelerate from a standstill to 100 km/h in less than 2.5 seconds.

Porsche was correct in emphasizing that the 935 is a track-only vehicle that cannot be lawfully registered for road use.

In August of 2019, Porsche began soliciting orders, and this limited-edition series rapidly sold out.

The new Type 935 is said to have a lightweight hybrid aluminum-steel platform chassis with stylish carbon fiber reinforced plastic bodywork, including rear-quarter window panels, according to manufacturer literature.

The roof is similarly built of carbon fiber reinforced plastic and has an escape hatch, as required by the FIA.

The massive rear wing, which was taken from the Porsche 911 GT3R, is made of carbon fiber reinforced plastic as well.
The famous “Moby Dick” 935/78 long-body variants bear a striking likeness in profile.

Ground-effects venturis are installed at the rear of the underbody to increase grip, and an air "Splitter" is used in the enlarged, aerodynamic nose.

A 115-litre FT3 fuel cell, an electrically triggered fire-extinguishing system, tire-pressure monitoring, and a special Recaro wrap-around racing bucket seat with six-point safety harness are all included for safety (HANS-device compatible).

Cushions can be moved laterally to accommodate wider drivers in this one-of-a-kind seat design.














Should an owner wish to invite a brave passenger, a similarly constructed passenger seat was among an extensive variety of racing-oriented modifications available.

Carbon fiber and Alcantara are used to decorate the interior.
Air conditioning and a central locking system are included as standard features.

A semi-circular, quick-release CFRP multi-function steering wheel with a pit speed restriction control is in front of the driver.

Many of the elements of this magnificent machine are inspired by Porsche's most pure race vehicles.

There are distinctive LED headlights, multiple LED taillights on the tail and rear wing endplates, and an FIA "rain light" similar to those on the Type 919 LMP1 Le Mans prototype coupes.

Coming from the GT3R parts bin you find the rear-view mirrors. The aerodynamic wheel covers are likewise inspired by the Moby Dick, and the dual exhaust megaphones have baffles similar to those found on the Porsche 908 and RSR.

The new 935 is powered by a Type MA173 alloy-cased water-cooled six-cylinder boxer-type engine with DOHC cylinder heads and VarioCam-Plus that is liquid-cooled and twin-turbocharged.

This fantastic engine produces 700 horsepower at 7000 rpm and sends it to the rear wheels via a reinforced and solidly installed seven-speed Doppelkupplung (PDK) transmission.

A track-day-optimized limited slip differential is included in the final drive. The driver has the option of using a short-shifting floor lever or paddle shifters to change gears.

The titanium shift lever is topped with a distinctive laminated wood knob inspired by the 917 prototypes and reintroduced on the Carrera GT.
In the front, McPherson struts are used, and in the back, a lightweight multi-link suspension is used.

Throughout, spherical bearings of the racing variety are employed.
The three-way adjustable shock absorbers and inserts, as well as adjustable front and rear anti-roll bars, were provided by Porsche Motorsport. Electro-hydraulic power-assist steering is used.

BBS forged one-piece light-alloy center-lock wheels, sized 11.5J in front and 13J in back, are shod with Michelin race tires sizes 29/65R-18 and 31/71R-18, respectively.

The 935's four-wheel disc brakes are quite powerful. The 390 mm diameter vented steel front rotors are gripped by six-piston aluminum monobloc racing calipers. 380 mm steel rotors with four-piston calipers are used in the rear.

ABS, Porsche's PSM (Stability Management), Stability Control, and Traction Control, all borrowed from the street-legal GT2RS, help with braking and handling.

Porsche claims that the PSM unit has been re-mapped to handle the wide Michelin racing tires that come standard, and that drivers will be able to modify all three electronic systems to their preference, or even turn them off completely.

The braking force can be matched to the driver's choice thanks to a driver-adjustable balancing bar. A trio of on-board air jacks, a Cosworth color dashboard display screen and data logger, and an analog boost pressure gauge positioned in the instrument panel beside a Sports-Chrono clock are all available for track use.

Few Porsches — or any cars, for that matter – combine as much performance, exclusivity, and excitement as the new 935.
