Recently, the new car-making force GMA launched a manual transmission sports car, the price reached 1.85 million US dollars, equivalent to more than 10 million yuan, GMA full name Gordon Murray automobile, as one of the most famous designers in the automotive industry, Gordon Murray's works include McLaren F1, etc., this 90s supercar is now worth more than 10 million US dollars, its newly established company GMA also inherits the design concept of McLaren F1, why the use of 6-speed manual gear such a 100,000 yuan family car configuration, let's analyze in detail.
4.0L self-priming V12+6 speed manual gear
As a model that inherits the concept of supercars in the 90s, its core powertrain naturally coincides with the 90s, and the high-speed self-priming V12 comes from Cosworth, a British racing engine manufacturer that supplies engines for a large number of racing cars, which is not common in the field of production cars.
Compared with the general wet sump engine, this V12 uses a dry oil pan to reduce the engine center of gravity, the angle between the cylinders is 65 degrees, the air is fed into the engine through four throttle bodies and a ramjet intake box, and the periscope air intake behind the passenger compartment is installed on the engine instead of the body, and the independent design can ensure that similar supercharged air enters the engine, increasing the low-speed power response of the self-priming engine.
The engine uses a large number of titanium alloys and new alloys, while reducing the weight to ensure stability at high speeds, the maximum speed of the engine is 11100 rpm, in the case of 12 cylinders, the total weight of the engine is only 177 kg, comparable to the four-cylinder engine of an ordinary car, the maximum power is 615 horsepower, the power is greater, but the weight is lower, which means a higher thrust-to-weight ratio.
In terms of gearbox, there are two reasons for choosing manual transmission, the first is three pedals and a gear handle, with more driving participation, in today's era of supercars mostly using automatic transmissions, a manual car will be favored by driving enthusiasts. Second, the manual transmission weighs less than the dual-clutch and automatic transmission with hydraulic torque converter, which is also in line with the overall lightweight design goal.
Like the engine, the gearbox also found a brand that is almost invisible in the field of mass production cars, that is, Xtrac, which is a company that specializes in manufacturing serial gearboxes for racing cars, such as F1 and FE, etc., all of which have Xtrac-made gearboxes, of course, the company's gearbox price is not suitable for mass production cars, the price of a single gearbox can be replaced by a BMW 3 Series, in addition, the life of the gearbox is also lower than that of ordinary family cars.
In addition to shifting gears with one-handed gear levers, gear shifts can also be made via a paddle ratchet mechanism mounted behind the steering wheel, and the gearbox weighs 81 kg, that is, the entire powertrain weighs only 258 kg.
Carbon fiber monocoque shell chassis + pusher suspension
T33 adopts a carbon fiber monocoque shell and aluminum structure hybrid frame, while ensuring strength, the weight is also much lower than the steel and aluminum hybrid structure of ordinary cars, aluminum frame and honeycomb carbon fiber structure are bonded together by adhesive, similar to Lotus's car-making concept, each component is in the case of ensuring strength, using punching and other lightweight design, the weight of the vehicle is only 1088 kg, this weight is similar to Changan Ben E-STAR mini car, propelled by a V12 engine, the big horse-drawn car, The performance is far beyond the average sports car.
Suspension design, the rear of the gearbox shell is directly connected to the control arm of the suspension, there is no secondary frame of the traditional car, the transmission shell is also the force structure of the body, this design can increase the length and adjustment range of the control arm, improve the torsional stiffness of the whole vehicle, the use of push rod structure, to ensure the grip of the vehicle tire, can adapt to different structures of the road surface for tuning, the tire is standard with Michelin Pilot Sport 4S.
Car selection detective point of view: Compared with today's large number of electric vehicles to make new forces, GMA has another way, take the high-end route, but also attracted a group of rich people who like old cars, although the price of a single unit is more than 10 million, but the quota of limited 100 units is snapped up within a few days, the sound wave of manual transmission and high speed self-priming V12 is full of mechanical charm, and electric vehicle brands use third-party motor battery suppliers, GMA also uses the mature technology of racing suppliers, for potential users, there is no concern about the high failure rate of small factories. Do you think such a manual car is worth selling for tens of millions? Discussion is welcome.
