Bertone GB110 opens a new chapter in the coachbuilder’s history

Bertone, one of the oldest and most respected Italian coachbuilders, wants a seat at the automaker table. The company followed arch rival Pininfarina into the supercar segment with a head-turning limited-edition coupe called GB110 that’s powered by a 1,100-horsepower engine.

Computer-generated images released by Bertone depict a wedge-shaped car that’s wide, low, and fairly pure in terms of design; it doesn’t look like a race car made just street-legal enough to wear license plates. Giovanni Sapio, the GB110’s project manager, points out that the overall design draws inspiration from past Bertone-penned concepts like the 1970 Lancia Stratos Zero and the 1968 Alfa Romeo Carabo.

Interior images haven’t been released yet. Similarly, technical details are few and far between. Bertone merely notes that the GB110’s chassis “is based on components from a German manufacturer” and that its mysterious engine develops about 1,100 horsepower and 811 pound-feet of torque. It spins the four wheels via a seven-speed automatic transmission. While we’re not going to fan the speculation flames, we should point out that the only German supercar with a mid-mounted engine, a seven-speed automatic, and all-wheel-drive is the Audi R8.

Regardless of what it’s powered by or based on, the GB110 is intriguingly configured to burn what Bertone refers to as “fuel made from plastic waste.” It joined forces with Select Fuel, which has reportedly developed and patented a technology capable of converting polycarbonate materials into renewable fuel. Feeding the engine what pretty much sounds like an alchemized and liquefied blend of plastic trash sends the coupe from zero to 62 mph in 2.79 seconds, from zero to 124 mph in 6.79 seconds, and on to a top speed of over 236 mph.

Bertone plans to make 33 units of the GB110 available globally. Pricing information hasn’t been announced, but it seems like the company already has big plans for the future. It announced that the new coupe is the first model in an upcoming series of limited-edition vehicles.

De Tomaso P900 uses synthetic fuel to spin past 12,000 rpm

It’s not a trendy electric hyper car. The Italian-built De Tomaso P900 is another kind of anomaly in the automotive upper strata where it lives: The P900 is propelled by a V12 engine that runs solely on synthetic fuel, all the way to 12,300 rpm.

Priced at about $3 million and limited to a production run of only 18 examples, the carbon-bodied P900 weights just less that 2,000 pounds.  Its 6.2-liter powerplant accounts for about a quarter of that weight.

Although De Tomaso is hedging the full specs on the car except to customers who have ordered one, the engine is expected to generate about 900 horsepower; it’s still in development until 2024, although the model is set to be revealed officially in the spring.

For customers clamoring to show off their P900s, it will be available prior to 2024 using De Tomaso’s F1-derived V10 engine. The design of the two-seater is pure science fiction, adapted from the De Tomaso P72, which used a carbon fiber monocoque chassis constructed to LMP1 standards and a 5.0-liter supercharged Ford Coyote V8.

“As a passionate automotive enthusiast, it is difficult for me to accept a silent EV-driven future,” said Norman Choi, De Tomaso CEO, in a statement. “We believe that alternatives do exist, and the development of our new platform, driven by synthetic fuels, is our solution for keeping this shared passion for the theatre of combustion engines alive.”

In pursuit of zero-emissions mobility, Choi says this new venture doesn’t envision a future that sacrifices “the crucial element which we all hold so dear — the soul and symphony of an engine.” 

Czinger 21C comes in 1,331-hp widebody version, too

Two months after Czinger introduced its 21C tandem-seater hypercar in regular and track-focused trims, there’s already another variant on the table. Jens Sverdrup, the company’s chief commercial officer, told Pistonheads that Czinger wanted to have a widebody derivative with a higher output ready for the Geneva Motor Show, but that didn’t happen. Sverdrup detailed the new version, explaining that engineers tweaked the 2.9-liter twin-turbo V8 and the twin high-power electric motors to increase output by an extra 98 horsepower, from 1,233 hp to 1,331, without increasing the weight of the 992-pound entire hybrid powertrain. This makes what was already the most power-dense V8 engine in the world even more power-dense. The widebody component shows itself in new bodywork over a wider track and wider tires, and it gets its own chassis tune. Said Sverdrup, “Anybody who buys one of our 80 21Cs can tick for a widebody version on the options list, giving them a hypercar that might not be the best for narrow Scottish or Welsh roads, but will definitely be great for the race track.”

Czinger’s spending the time before deliveries begin in 2021 honing engine characteristics to ensure tractability throughout the V8’s 11,000-rpm rev range. We’ve been promised a coupe that’s tame around town, Sverdrup saying, “With the hybrid system you can lean more on the batteries at low revs for more refinement at low speed.” Get above 6,000 rpm, however, and it apparently sounds like “an old F1 engine.”

The California company’s vision for life after the 21C is also in the works, with three models slated to launch starting in 2023. These could be more practical than the opening act, adopting 21C philosophies from the powertrain to the build, and continuing the push toward synthetic fuels. With Czinger backed in part by 3D-printer Divergent 3D and Hong Kong venture capital, engineers are already considering how to design a monocoque with built-in cavities for wiring and fluids, and “complex internal structures that enhance crash safety.” 

The 80 planned builds for the 21C should keep the company busy for the next few years, each car said to take 3,000 to 4,000 man-hours to print and assemble. As for the question of whether Czinger will be around that long, of course, one never knows, but the company supposedly has funding for the next three projects already and, unusual in this space especially, Czinger isn’t asking for deposits for the 21C in order to pay for production. Seeing the dealer network is planned to include “20 established supercar sellers in Europe” by the end of this year, further insight into what’s ahead shouldn’t be long in coming.

Czinger releases full specs on 21C hybrid hypercar

A week ago, LA-based Czinger teased its 21C hypercar with a video and a promise of “dominating performance.” Now that all the specs are out before the coupe’s reveal at the Geneva Motor Show, on paper at least, it appears “dominating” was the correct choice of words. We’ll start with the performance: Zero to 62 miles per hour in 1.9 seconds — making 0-60 perhaps faster; the quarter-mile in 8.1 seconds at 170 mph; zero to 186 mph and back to zero in 15 seconds; zero to 248 mph and back to zero in 29 seconds, which would eclipse the Koenigsegg Regera’s record of 31.49 seconds set last September.

Assuming the 21C can bring those numbers to life, how does the coupe do it? There’s a 2.88-liter twin-turbo V8 with a flat-plane crank stowed amidships driving the rear wheels, good for 950 horsepower. (To get a sense of the march of progress, the 2.855-liter twin-turbo V8 in the 1984 Ferrari 288 GTO produced 350 hp.) Each front wheel gets a high-powered electric motor, serving up all-wheel drive and a combined output of 1,232 horsepower and 600 lb-ft of torque at 10,500 rpm, 500 rpm short of redline. The 21C in standard road guise without the big rear wing has a curb weight of 1,250 kilograms (2,756 pounds), and with a metric horsepower rating of 1,250 hp, we’re talking about a 1:1 power-to-weight ratio. The 21C Lightweight track-focused car with the big rear wing weighs just 1,218 kg (2,685 pounds). Shifting through a seven-speed automated manual transmission, the road car maxes out at 268 mph, the track car produces more than three times the road car’s downforce so its top speed comes in at 236 mph.

The e-motors get juice from a lithium-titanate battery, the same pack composition used by the Mitsubishi i-Miev and Honda Fit EV, an integrated starter-generator helping to deliver power where needed. Czinger says the entire powertrain was designed and is built in-house, and it’s flex-fuel — owners can fill up with Vulcanol, described as “a renewable methanol made from captured carbon dioxide,” assuming they can find it.

Czinger is only making 80 examples of the 21C, using its proprietary “vertical assembly,” 3D-printed build processes that combine carbon fiber, high-performance alloys, and other materials, topped off with book-matched carbon fiber bodywork. Road & Track has a good writeup on the production system. Company founder Kevin Czinger explained that the 3D-printed parts are expected to last the lifetime of the car, but if any need to be replaced, they can be dissolved into their original powder and reconstituted to serve a different purpose.

Each 21C comes with a reported price of $1.7 million before the obligatory options and fripperies. We look forward to checking this one out in Geneva, and we’ll take the one with the wing, please.
