The Lamborghini 400-GT Monza by Nembo: the Missing Gem

The origin of the Lamborghini 400 GT Monza

In 1963, the 350-GTV was introduced as the 1st prototype by a new Italian company, Lamborghini. Dallara designed a chassis which was built by Neri & Bonacini. Established by Giorgio Neri & Luciano Bonacini in Modena, and known as Nembo, it was a coachbuilding and mechanic workshop generally working on race cars for Maserati and Ferrari, also accepting orders from private clients.

They continued their cooperation with Lamborghini, making the chassis for the 1st production model, the 350-GT, but gave it up later due to the increase in the orders for production. This was not the end.

Whereabouts

At the 1967 Barcelona Motor Show, where the new model, Miura, was also presented by Amato, the Spanish Lambo agent, a car was of as much interest, if not more: Lamborghini 400 GT Monza .

This exotic one-off was hand-built on a 350-GT chassis, no. 01030, and equipped with the stronger engine of the later model, 400-GT; guess by who, Neri & Bonacini. In a recent interview with Octane magazine, Giorgio Neri mentioned that the car was built earlier in 1963 or 4, for an American commissioner, probably to race at Le Mans, but it never happened due to the homologation rules. What we know is that the very car we see today was finished by June 1966.

Back to the Barcelona Motor Show, a wealthy Spanish sportsman and race driver falls in love with the Lamborghini 400 GT Monza and succeeds in the negotiations to buy it.

The car, then badged as Jarama after its new home by the owner, had covered just 7136 km by 1970, when it was left in his garage and maybe forgotten.

For a long time after, many journalists and enthusiasts had been looking for the Lamborghini 400 GT Monza and there have been some rumors about its whereabouts. It was missing until 1996, when Bonhams, which was known as Brooks then, announced that they have found the missing gem in its totally original condition. The owner had passed away a short while before and it took 9 years until his family decided to sell it.

It was auctioned at Bonhams’ London Olympia sale on December 5, 2005 and sold at for $315,000 buyer’s premium included.

Tecnical specifications

As mentioned, the Lamborghini 400 GT Monza was built on a 350-GT chassis which was a redesigned production format of the 350-GTV’s race chassis.

Designed by Gian Paolo Dallara and Paolo Stanzani, it had a tubular steel frame structure with square tubing for the central floor and round tube for its superstructure. For the suspension, it used all-independent, double wishbones with coil springs over telescopic shock absorbers and anti-roll bar both in the front and rear. It also used 4 wheel Girling disk brakes.

It was powered by a front-mounted 400-GT model engine which was a naturally aspirated all-aluminum block V-12 @ 60°, wet-sump DOHC with 2valves/cyl, with a bore/stroke ratio of 82/62mm, a compression ratio of 10.2:1 and a total displacement of 3929cc. Fed by 6 twin-choke Weber 40 DCOE 2 carburetors, it was able to produce 320 bhp @ 6500 rpm and 375 Nm @ 4500 rpm of power & torque respectively which was delivered through a 5-speed ZF manual gearbox and a Salisburry limited slip differential to the rear wheels and able to propel the car to a top speed of around 250 km/h.

Bertone has once again outdone itself with the new eco-friendly hypercar, the GB110. What’s special about it? The fuel is obtained by transforming plastic waste.

Every year, Top Marques Monaco manages to attract luxurious brands and models. The renowned event also showcased a new Italian hypercar, the Bertone GB110. Besides its stunning beauty, the hypercar has another remarkable feature that makes it highly intriguing: its ecological spirit. Yes, nowadays, hybrid and electric vehicles are a reality in the industry, but the approach to environmental respect takes a different form here.

From “bi” to Three-Dimensional

For almost two years, the project was the talk of the town following some detailed renderings. But transitioning from “bi” to three-dimensional is a vast leap. This is why enthusiasts were keen to see if the initially proclaimed qualities would hold up in reality. The company’s reputation, earned over years of distinguished service, suggested they would. After sadly going bankrupt in 2014, before rising from its ashes, the designers aimed to astonish visitors. Judging by the initial reactions, they succeeded.

On the occasion of the company’s 110th anniversary, the “stylists on four wheels” unveiled the GB110, and it must be said: it knows how to make an impression. The bodywork of the beast deviates from typical market clichés, and given the many expensive hypercars on sale, this already speaks volumes about its distinctive personality. The front exudes natural charisma with its narrow headlights and the thin extended section between the slightly raised lights above the hood, while the rear displays imposing strength.

Is the Engine from the Lamborghini Huracan? Clues Point to Yes

Previously, company spokespersons admitted to drawing inspiration from a pre-existing car, without specifying which one. We may have to live with this mystery, although the prevailing theory suggests it derives from the Lamborghini Huracan. This is implied by the “beating heart,” a ten-cylinder 5.2-liter engine augmented by a pair of turbochargers, capable of unleashing 1,100 HP and 1,100 Nm of peak torque.

The design team claims it can accelerate from 0 to 100 km/h in 2.79 seconds, from 0 to 200 km/h in 6.79 seconds, and reach 300 km/h from a standstill in just 14 seconds. The top speed exceeds 380 km/h. The exuberance is delivered through a seven-speed dual-clutch transmission to all four wheels.

Impressive numbers, but almost overshadowed by the unique fuel system. Instead of relying on traditional gasoline and diesel, the engineers opted for something truly original: plastic waste. In collaboration with Select Fuel, the company developed a patented technology to convert polycarbonate materials into fossil fuel. Speaking about what motivated Bertone to take on this challenge, CEO Jean-Frank stated, “We believe that tackling pollution requires diverse solutions employing various technologies. Plastic waste must be treated as a valuable resource. Through our partnership with Select Fuel, we transform waste into its original form.”
