911 Porsche World - - Contents -

This is it. The 911 resto­mod to end all resto­mods, all 4.0litres and 500hp of it. We give you Singer’s DLS, now in phys­i­cal form hav­ing­made the leap from com­puter ren­der and nicei­dea-on-pa­per to stun­ningde­but at the Goodwood Fes­ti­val of Speed.

DLS stands for Dy­nam­ics and Lightweight­ing Study in Singer par­lance and it means turningev­ery­thin­gup to 11 in the quest for cre­at­ingthe most ex­treme, the most ca­pa­ble and the most pol­ished ex­pres­sion of a re­stored and mod­i­fied Porsche 911 ever. The head­line fig­ures are stag­ger­ing for a 911 with an air-cooled flat six and di­rectly mir­ror those of Porsche’s lat­est and great­est wa­ter-cooled 911 GT3 en­gine, in­clud­ingthe abil­ity to rev to fully 9000rpm.

In­deed, the Singer mo­tor ap­pears to go even fur­ther. The new 4.0-litre GT3 will rev to 9000rpm, but pro­duces peak power at just 8250rpm. Singer claims its new en­gine is crankingout peak power at 9000rpm and thus will likely rev even higher. Either way, the en­gine is the re­sult of a col­lab­o­ra­tion be­tween Singer, the Wil­liams F1 team’s Ad­vanced Engi­neer­ing off­shoot and one Hans Mezger.

Yes, the man re­spon­si­ble for cre­at­ingthe 911’s iconic flat six has con­trib­uted to the DLS’S en­gine de­sign. High­lights of the en­gine spec in­clude four ti­ta­nium valves per cylin­der, dual over­head cams, ex­ten­sive use of mag­ne­sium and light­weight ma­te­ri­als to re­duce mass, light­weight throt­tle bod­ies with F1-in­spired up­per and lower in­jec­tors to en­hance per­for­mance and driv­abil­ity and a unique and op­ti­mised oil­ingsys­tem to

im­prove lu­bri­ca­tion and cool­ing.

Of course, the 500hp en­gine is just the be­gin­ning. The de­tail­ing and de­lights abound. An ad­vanced aero pack­age cre­ated by Wil­liams com­bines com­pu­ta­tional fluid dy­nam­ics with old­school knowhow from Nor­bert Singer, he of 956 and 962 fame. The pack­age is said to en­tirely re­move front axle lift cour­tesy of items like a mod­ern take on the clas­sic duck­tail spoiler and dual-layer rear win­dow with func­tional aero. It also in­cludes what may turn out to be the DLS’S sig­na­ture fea­ture, those en­gine in­takes in­te­grated into the rear side win­dows.

Else­where, there’s multi-link dou­ble wish­bones front sus­pen­sion, alu­minium rear trailin­garms, be­spoke mas­sop­ti­mised dampers and a body shell op­ti­mised for stiff­ness and low mass. As with pre­vi­ous Singers, the pan­els are all car­bon-fi­bre but all are unique to the DLS. Next up is the be­spoke, sixspeed man­ual gear­box with mag­ne­sium cas­ings and hol­low shafts for max­i­mum re­duc­tion of ro­tat­ing mass. Singer has even re­duced the box’s length to re­po­si­tion the en­gine for­ward for im­proved weight dis­tri­bu­tion.

Then there are the 18-inch cen­tre-lock wheels, cre­ated in part­ner­ship by BBS and Wil­liams, unique Miche­lin Pilot Sport Cup 2 tyres, ce­ramic brake discs, switch­able trac­tion and sta­bil­ity con­trol by Bosch, and, well, an aw­ful lot more. In­deed, even the cabin’s engi­neer­ing is ex­treme. The in­stru­ments are lo­cated on a float­ing car­bon-fi­bre panel, the raised man­ual gearshift with ex­posed ti­ta­nium and mag­ne­sium link­age links with shift lights in­te­grated into the tachome­ter and the door cards alone are in­cred­i­bly in­tri­cate.

In short, Singer has dra­mat­i­cally upped the ante when it comes to re­stored and mod­i­fied 911s. Of late, sev­eral ri­val out­fits around the world have cre­ated 911s very sim­i­lar in look and char­ac­ter to Singer’s orig­i­nal resto­mods. But it’s hard to imag­ine any­one di­rectly chal­leng­ing this new DLS for tech­nol­ogy and at­ten­tion to de­tail. Ex­actly how much the DLS will cost or when you might be able to get your hands on one are un­known, the DLS re­mains a ‘study’ for now. What­ever the price, the DLS is a stag­ger­ing rein­ter­pre­ta­tion of what it means to be an air-cooled 911. It’s cer­tainly sober­ingto re­mem­ber that some­where un­der­neath all that car­bon­fi­bre fin­ery and 500hp tech­ni­cal mas­tery is a hum­ble 964 Car­rera.

Singer takes the ‘resto/retro’ Porsche scene to new heights with Dy­namic Light­weight Study, a col­lab­o­ra­tion be­tween Singer, Wil­liams and Hans Mezger. Quite a cast
