Well here is a new Ford Truck you have never heard of

I think that what may be less well known is that Ford sold a Low Cab Forward (LCF) truck for a few years but they must not have sold well:

While looking for pictures of the Ford I was very surprised to find that Chevy seems to be selling some now:

I just spent a week in Italy and Croatia and don't think that I saw any trucks over there only going 56mph.

I don't see any drawbacks to cab forward designs that you don't have in pusher motorhomes except engine noise yet those are very popular here.

That is the speed limit for Trucks in the EU. Although a Volvo Cabover set the world speed limit for a Truck. Interesting comparison US Motorhomes,like the Class A pushersdo not have the engine in the front

Volvo Trucks is claiming two new world land speed records. It's custom-built "Iron Knight" truck reportedly achieved an average speed of 131.29 km/h (81.58 mph) and a time of 13.71 seconds over 500 m (1,640 ft) and 169 km/h (105 mph) with a time of 21.29 seconds over 1,000 m (3,281 ft), both from a standing start.Aug 24, 2016

These debates are hilarious.

Got absolutely nothing to do with the 56mph speed limit. Owner drivers here with EuripeanCabovers are getting better fuel,economy at 70mph than their previous conventional truck.

Can you post the data of before and after fuel economy with links because my data shows that the most aerodynamic cabover being the Volvo VF at .59 Cd and the best aerodynamic conventional is the Navistar Prostar at a lower drag coefficient of .53 Cd. And that is wth the Volvo at 85 km/h(52 mph) and the Prostar at 65 mph.
S

So please, post these links of drivers getting better fuel economy at 70 mph in their modern cabover versus a modern conventional cab.

Well the Navistar Prostar was the CAT truck a total failure here, but not in the US
European Heavy Truck fuel usage

I think it's butt ugly. Having driven Class 8 trucks for 30 years, I prefer a conventional. Don't want to be first on the scene with the radiator cap in an accident.

Hard on the knees.

They the modern ones have exemplary saftey records as well as having exemplary secondary safety features.
Bulk of the US heavy trucks are owned hy the Europeans anyway
" Butt Ugly" no not many would agree with you outside NA

No they do not. That is why they are getting better Fuel Economy here and Especially in Europe, where fuel is liquid gold. The Barn Door Front on US Conventials makes them as aerodynamic as a Model A Ford. Conventials are now called" American Style" in New Zealand. We have all three in Australia, European, Japanese and US and " American Style" See IVECO above
JMC is building it for the Chinese market. Otosan the Turkish builder and developer for the Eurasian market

They are getting better fuel economy in Europe because of the 56 mph speed limit, not because of better aerodynamics. NA trucks are limited to 65-75 in many areas except for California where the speed limit is 55 mph. Read the study in the link I posted written by Volvo where even they state conventional cabs are more aerodynamic due to our higher speed limits.

Fleets here buy all types of trucks. Cabovers are becoming more prominent . in distribution duties they are the only style of truck

Robert, if you want to read more about why Europe is predominantly cabovers then here is a good read. It is even written by a European from Volvo trucks so you you won't say it is bias.

Abstract The aerodynamic situation for trucks on the European market differs from that in North America on a number of points. Perhaps the most significant difference is that in Europe trucks are of the CoE configuration (Cab over Engine) and in North America trucks are of the conventional type with a hood. Another major difference is that trucks in Europe are speed limited to 90 km/h (56 mph) which of course means that aerodynamics as a whole has less of an impact there. These differences are primarily dictated by different legislations, which in turn have a lot of different side effects. This paper will high-light some of the differences and their impact on aerodynamics, as well as taking a look at possible future ideas such as: extended front or short nose, ride height adjustments, convoy driving, etc.

Introduction Historically most trucks have been of the conventional type. But with the increasing need to make transportation more effective, maximizing load at the expense of space for the driver, has predominantly in Europe, resulted in trucks with the Cab placed on top of the engine (CoE). All these constraints are regulated by legislations. These legislations are, and have been, very different in European compared to in North America. (There are differences in other parts of the world but those will not be considered here). Of all different legislations it is the ones concerning the length, height, width, weight which has had the biggest impact on the over all shape of the trucks, and hence the aerodynamics. But there are also differences in culture, infrastructure and geography which have contributed in making the detailed design of trucks on the two continents different.

I know why Europe is Cabovers, but Australia , Russia, Turkey and South Africa are as well. We are not crawling along at 56mph. They do not outside Europe either.
