Or diesel without the NOx. Which, in theory, would give better fuel economy and possibly better torque. And it will ship in cars in the 2019 model year (so possibly as early as late next year).&lt;p&gt;To me, it sounds like a &amp;quot;Don&amp;#x27;t pass&amp;quot;[1] bet on electric cars. Which they also are working with Toyota on electric cars so perhaps it is a fall back plan. It will be interesting to see how it fares. There are a lot of products that are built as the other side of an industry change bet. Sun created a workstation on the 68040 in case the SPARCStation didn&amp;#x27;t meet expectations as an example.&lt;p&gt;[1] In the dice game Craps, the &amp;quot;Don&amp;#x27;t Pass&amp;quot; bet is against the current player &amp;#x27;winning.&amp;#x27;</text></comment>

I already have a 2016 Mazda 3 that gets around 40MPG (even though it&amp;#x27;s not a hybrid) and it&amp;#x27;s already pretty peppy.&lt;p&gt;Probably the best car I&amp;#x27;ve owned, and I&amp;#x27;ve owned several nice sports sedans.  Getting 40MPG is too convenient when you make longer commutes, not to mention the thing cost ~20k at 0% APR.  Blows any hybrid out of the water for total COO.</text></comment>
