It could be another two reasons to issue the hard top for 124 - track days and homologation. As I know some tracks prohibit to use open cars for trackdays. Also it can be a part of the homologation process. Just take a look at any homologation papers, all open cars used a hardtop as a mandatory.

What is the problem to get even 1000HP? The question how they destroy the balance of the car. Have you ever driven tuned car? Will get check engine light once in a week, always worry about spark plugs and possible engine damage. What will happen with all heat? How did they improved cooling system? Who will pay for all mistakes that tuners do? The Owner! ☏ Z957 ☏

What a stupid idea to install batteries in the truck. They should be in the trailer. Trailers usually spend about 6-7 hours for unloading. in North America every retail store has a bay for 2 trailers. Truck always pick up the empty trailer and left the loaded one. So, truck always moves and does not have a time for charging. Trailers always have a time (about 12 hours) for charging. Logistic scheme is simple, trucks deliver full loaded trailer from logistic centers to the retail stores.

Also I think this technology has a fake name. Mazda uses a fireball, the same principle used Honda Civic СVCC and russian GAZ 3102 in late 70s. When the gasoline mixture burns itself as in a diesel type motors we can call it engine knock. It is a common thing if you use a lean mixture or low octane fuel. So, Mazda adopted 70s technology in modern engines I am just curious, what is CR of Skyactive-X if it can burn fuel by the pressure? :)))))))

Because it is just a marketing. They want to have better engine response, without turbo lag. All major manufactures have been used this technology since 20s. But supercharger uses engine power. The engine with a supercharger is less efficient then with a turbocharger. The most efficient way in my opinion is to use electric supercharger + turbo. It is expensive technology and can not be used now for cheap cars as Mazda. I do not believe that Mazda 3 with Skyactive-X even can achieve 5 l/100 km at highway because of the volumetric supercharger.

By the way high pressure air supply pump was used by Alfa Romeo for amercan market engines in late 70s-early 80s. The summit of this technology was MY81 Spider. EGR+Air Pump+SPICA with air receiver+Cat+VVT

So, what Mazda promises? I tried current SKYACTIVE engine at Mazda CX5. The fuel consumption is VERY high in compare to 1.4 Turbo Multiair of Dodge Dart. I understand the cars a different but.... At highway I was able to rich 7.3 in Mazda. Dodge fuel consumption at the same road is 6.0 In the city Dodge consumes 6.8-7.3 l/100km. So what is the point? Better throttle response because they use mechanical supercharger? But it is already known fact. Better fuel consumption? By burning more fuel you cannot get better fuel consumption

Journalists as always say a lot of bull shit. For instance in this video the guy says that Alfa has 8 speed dual clutch gearbox.max_pershin ha risposto a messaggio nella discussione in Notizie e Scelte Strategiche dal mondo dell'AutoHow they can buy FCA if Exor owns about 30% of the company? FCA is at the stock market with a huge quantity of the shareholders. Revenue of Great Wall in 2016 was about 14.9 billions USD, revenue of FCA in 2016 was 111 billions USD. In 2016 Great Wall sold 1 mln cars, 5 times less than FCA. Is it another joke issued by Autonews?To be honest, I have almost everyday troubles with Multiair of Dodge Dart. But my car is not stock, it has Marelli tuning boxes, also I live about 1500m above the sea level. So, throttle mistake. Yes, happened about once in a month. Never happened under the load, just in a light traffic, about 1300 rpm. To clear the mistake is enough to turn off/on the engine. Another mistake, check engine light, happened once in a week in a summer time and once per month in winter. The reason is a reach mixture. It influenced on performance. To get rid of it I need turn off/on the engine as well. In my opinion Multiair system has a kind of safe mode, that not allow engine to be near the edge of oil temperature or reach fuel mixture. Too intelligent system that depends on atmospheric pressure, temperature and humidity. When something is beyond of the set up level the system shows a mistake that is not critical but warning. Lights are not a signals of the problem that something is broken, no it is the signal that something is beyond of normal level. ☏ Z957 ☏max_pershin ha risposto a messaggio nella discussione in Notizie e Scelte Strategiche dal mondo dell'AutoRussian market is not a Klondike anymore. Russian economic depends on oil mostly. I would say they cannot do anything but oil extraction. So, oil prices are low, and will be low for many years ahead. I would say FIAT made right decision. P.S. Mostly they, and a lot of other companies, stopped sales because of the special emergency system that must be installed in any new car. Big money involved in testing and government required crash tests. No reason to develop it for rather small market as Russia. ☏ Z957 ☏Why they drifted on the tack? Rally driving on the track? The test is about how to drive wrong. Driving mistakes in every single curvemax_pershin ha risposto a messaggio nella discussione in Notizie e Scelte Strategiche dal mondo dell'AutoUtopian idea. DTM is a local (EU, mostly German) championship. Sergio might be willing to invest in global activity, known in North America and Asia. In my opinion there are only 2 championships where Alfa can be represented globally, WEC and F1. Anyway, in both championships cars use hybrid technologies. The same technology has to be used on production cars, to advertise it.. My conclusion, we will not see Alfa in racing till Hybrid technology will appear in the model line. 2020-2021??? ☏ Z957 ☏
