<p>The objective of this metamorphosis is to ensure closer ties between the research and development carried out&nbsp;in F1, the concerns of everyday motorists and the new challenges faced on economic and environmental&nbsp;fronts, without detracting from the quality of the show or the level of competition.&nbsp;The change fits perfectly with Renault’s powertrain strategy, which is founded on:</p>
<ul>
<li>  An unmatched commitment to electric motors,</li>
<li> Ongoing improvements to the efficiency of its internal combustion engines with a view to achieving&nbsp;spectacular fuel consumption and CO2 emissions gains.</li>
</ul>
<h1>What will change in 2014</h1>
<p>F1 is about to undergo one of the most important transformations in its history. After a 7-year&nbsp;period during which engine specifications were frozen, the new regulations due to come into effect in&nbsp;2014 will see engine makers play a central role in the cars’ overall performance. By placing engines&nbsp;at the very heart of the sport once again, motor racing’s blue riband competition will stand out more&nbsp;than ever as a showcase for cutting edge technology.</p>

<p>The gauntlet the FIA has thrown down to F1&rsquo;s engine&nbsp;makers for 2014 is to reduce the quantity of fuel needed&nbsp;for a Grand Prix by almost 40 %, yet still maintain&nbsp;the same level of performance and power outputs (i.e.&nbsp;around 750 horsepower) as today.&nbsp;The countdown to 2014 is already well under way as the&nbsp;engineers turn their attention to the development of what&nbsp;is termed a &lsquo;power unit&rsquo; that combines a downsized&nbsp;turbocharged engine with two electric motors to recover&nbsp;braking and exhaust heat energy.</p>
<ul>
<li> Downsized internal combustion engine: switching from a V8 to a V6 architecture, with a&nbsp;cubic capacity reduced by one-third from 2.4&nbsp;to 1.6 litres; as well as turbocharging (single-stage compressor), plus&nbsp;engine torque capped at 15,000rpm for a power&nbsp;output of approximately 550 horsepower&nbsp; </li>
</ul>
<ul>
<li>New ‘Energy Recovery System’ (ERS): kinetic&nbsp;energy (ERS-K) and exhaust heat energy (ERS-H) is&nbsp;recovered by two electric motor-generator units&nbsp;named MGU-H and MGU-K.</li>
</ul>

<p style="text-align: center;">©&nbsp;DPPI</p>
<p>The new restrictions specified by the 2014 FIA regulations are threefold:</p>
<ul>
<li>A <strong>double-restriction concerning fuel</strong>: the amount of fuel that can be used during races&nbsp;has been reduced to a maximum of 140 litres; and a fuel flow reduction, with maximum fuel flow rate reduced to 140 litres/hour.</li>
</ul>
<ul>
<li>A <strong>double restriction concerning the flow of electrical energy</strong>: the amount of energy that can be recovered during each lap has been reduced and teh amaoudn of energy that can be restored has also been reduced.</li>
</ul>
<ul>
<li><strong>Development costs have been limited</strong> and the <strong>number of engines each driver</strong> can use in the course of the&nbsp;season has been further capped: five per driver in 2014, then four per driver from 2015 (compared to eight per driver&nbsp;at the moment).</li>
</ul>
<h1>Renault, a major player in this technological metamorphosis</h1>
<p>Wtih 11 Constructors’ crowns (either as an engine&nbsp;supplier or as a team in its own right) and 151 victories,&nbsp;Renault stands out as one of the discipline’s key&nbsp;players<em>.&nbsp;</em>Renault contributed significantly to the establishment of&nbsp;the new regulations through its participation in the&nbsp;different working groups set up by the FIA since 2009.</p>

<blockquote>
<p>“At the time, there was a perceived distance and lack of&nbsp;consistency between the technology employed in F1&nbsp;and that used for mass production vehicles, from both&nbsp;the economic and environmental angles. It was&nbsp;therefore necessary for F1 to undergo a significant&nbsp;change in order to reconcile these two realities.” &#8211; Rob&nbsp;White, Technical Director, Renault Sport F1.</p>
</blockquote>
<p>In order to continue competing in F1, Renault was&nbsp;adamant that the discipline should recover the&nbsp;reputation it enjoyed as a technological pioneer before&nbsp;the engine freeze regulations came into force in 2007.&nbsp;During these group consultations, Renault proposed&nbsp;that the race engines’ specification should be based on&nbsp;‘road relevant’ criteria, with energy efficiency as the&nbsp;number one priority. The watchwords of this shift&nbsp;towards engines that are also closer to the technology&nbsp;used by mass production vehicles were downsizing,&nbsp;supercharging, an upper limit on engine speeds and the&nbsp;controlling of costs to stay close to production&nbsp;technologies. Energy efficiency emerged naturally as&nbsp;the key consideration.</p>
<p>See you in a couple of months for more details on this power-unit, which will most likely revolutionize the world of Formula 1!</p>
