In the wake of Daewoo's bankruptcy, Chery somehow ended up with a complete set of prints/CAD models for the Matiz before GM bought up Daewoo's assets out of bankruptcy. Chery then proceeded to tool up and put the QQ into production but, to the best of my knowledge, has never really explained just how they wound up… » 3/27/15 2:48pm Yesterday 2:48pm

In a true free market established laws apply equally to all. Elon Musk and Tesla just don't think the rules should apply to them. They are asking for an exception to state law that will create a monopoly just for them, allowing them to sell their vehicles at one non-negotiable list price and export every penny of…

The thing I remember about that was the cars of that era had diffuser tunnel blockers to limit downforce (and increase drag) and the Hanford Device (sort of a really big upside-down Gurney Flap) on the rear wing to increase drag — to slow the cars down and add a low pressure zone that aided drafting/slingshot passes. » 3/17/15 5:47pm 3/17/15 5:47pm

Military deuce-and-a-half and five-ton trucks with mechanically-injected diesels. Not fast, not comfortable, but mechanically forgiving of many abuses, can run on pretty much any flammable liquid for a time (or as long as the flammable liquid holds out in some cases), lots of spares available at bases throughout North… » 3/17/15 2:38pm 3/17/15 2:38pm

Because of the CHIL-dren. Really. Children were getting backed over in their own driveways by mommy's Suburbarn 'cause the ground point (where you can see the ground from the driver's seat) out the rear of a 'burb is dozens of feet behind the actual vehicle — it's further away with shorter drivers due to a lower eye… » 3/09/15 5:18pm 3/09/15 5:18pm

@dal20402 has the right of it. The medium-duty engines (F650/750) are very similar to the ones in the light-duty (F250/350/450 pickup) in terms of hardware, but with differences in inlet, turbo, and exhaust (usually - I haven't seen these to know for sure, but I was very familiar with the older 6.0L Navistar engine,… » 3/04/15 5:20pm 3/04/15 5:20pm

I've often wondered just how effective these in-the-engine-compartment "cold" air intakes really are compared to a full airbox that draws air from outside the engine compartment. Seems to me this design is biased toward getting lower inlet temps (and thus bigger numbers) on a chassis dyno test where the SOP is to have… » 3/04/15 11:05am 3/04/15 11:05am

Automakers do market research. Customers tell the market researches they want gauges instead of idiot lights. Automaker puts (accurate) gauges into cars. The 90% of customers who just want a transportation appliance freak right out that their oil pressure varies with engine speed and temperature, and that coolant… » 2/27/15 10:37am 2/27/15 10:37am

Silver tube is ducting to probably the outside of the exhaust (this is the McLaren) so it doesn't cook off the bodywork. Race cars spend more time under load than street cars, so more heat. Other possibilities include electronics cooling or transaxle cooling. » 2/25/15 11:13am 2/25/15 11:13am
