For the 20th B.R.D.C. International Daily Express Trophy race at Silverstone, the Club amassed a small but fairly representative field of Formula One cars. Heading the entry were Hulme and McLaren in the two impeccably-prepared McLaren M7A-Cosworth V8s, which finished first and third in the Race of Champions, and Ferrari sent over two cars, one a new, slightly sleeker-chassised V12 with the engine lower-mounted than hitherto, and the other the car which Amon normally races. Drivers were the young Belgian, Ickx, and Amon, and though the New Zealander tried both cars he decided he preferred his own, and Ickx raced the new one. Graham Hill had a solitary Lotus 49-Cosworth V8 which was entered by Gold Leaf Team Lotus, and B.R.M. were well represented with Rodriguez in the Bourne-built, Terry-designed P133 V12 and Spence in the similar, T.A.C.-built P126. Also in a P126 was Courage, having his first F1 race this season for Parnell, and Hobbs had Bernard White’s relatively unsorted Tasman 2-litre B.R.M. P261 chassis, specially lengthened by the works to accommodate the new V12 engine. Also B.R.M.-powered was the lone works Cooper T86B, with Gardner driving, as Scarfiotti was away practicing for the Targa Florio and Redman was reputedly testing F.2 Dino Ferraris in Modena. Rob Walker had acquired a new Tasman Lotus 49 chassis to replace the one lost recently in a fire at his Dorking headquarters, Siffert driving as usual; Bonnier was in his 1967 McLaren M5A-B.R.M. V12, and the Swiss Moser had the ex-Hulme, ex-Ligier Brabham BT20-Repco V8. Lanfranchi completed the field in a 2.7-litre Climax 4-cylinder powered Brabham BT23.
Withdrawn entries included a second Parnell B.R.M. for Attwood and Sheppard’s Mallite McLaren fitted with a 3-litre version of the original Climax Godiva V8 for Taylor. Two works Brabhams were listed, but were not complete.
Last year’s G.P. practice record of 1 min. 25.3 sec. by Clark in the Lotus 49 looked a little sick compared with this year’s speeds, Hulme taking pole position with 1 min. 24.3 sec. to Spence’s 1 min. 24.9 sec., McLaren’s 1 min. 25.1 sec. and Rodriguez’s 1 min. 25.3 sec. Behind these four on the front row came Amon at 1 min. 25.5 sec., Hill 1 min. 25.6 sec., Ickx 1 min. 26.4 sec., and Siffert 1 min. 27.6 sec.
After a poignant silence in memory of the late Jim Clark, the field were given a maximum of three warming-up laps, and from the start McLaren took an immediate lead ahead of Spence, Hulme, Rodriguez, Ickx, Hill, Amon, Courage, Bonnier and Gardner. Lap 2 and the leading bunch were all scratching hard to draw out some sort of advantage; Courage was briefly ahead of Amon at Copse and Siffert and Gardner were both by Bonnier, who was being harried by Hobbs.
The leading McLarens, B.R.M.s, the lone Lotus and the two Ferraris soon towed each other away from the rest of the field, with Hulme slotting by Spence into second place on lap 4, then being repassed by the B.R.M. Lanfranchi had already stopped for a plug change on his 4-cylinder, and at the start of lap 6 Spence led McLaren into Copse, and was re-passed on the way out to Maggotts to remain the meat in an orange McLaren sandwich for a short distance before chopping by again and leading the bunch on lap 7 from Hulme, McLaren, Rodriguez and Hill, all nose-to-tail. Amon and Ickx had become slightly detached in the works Ferraris, but as they sped down Hangar Straight on that lap a stone was thrown up from Spence’s B.R.M., smashing Hulme’s goggles and giving him a nasty moment which dropped him back to seventh.
Almost immediately Rodriguez’s B.R.M. V12 began to misfire, an ignition lead dropping off, and he stopped before Maggotts, replaced the wire and drove on to the pits, where a more lasting repair was made. By lap 9, with Spence leading narrowly from McLaren, Hill was third in the lone Lotus, Amon was a close fourth and Hulme, whose eyes had stopped watering, was already on his tail and looking for a way by. Positions remained unchanged until lap 14, when the Lotus’ V8 engine died, and, seeing a lot of fluid resting in the vee, Hill thought the engine had suffered a serious breakage and had thrown water. In fact, a fuel pipe had split, and the fluid was petrol, but he was out anyway, and walked back to the pits. Hulme had nipped by Amon on this lap, and was going out after Spence, who had been re-passed by McLaren. lckx was falling back in fifth place with the very new and understeering Ferrari, with Siffert some distance behind, followed by Courage, Gardner, Hobbs, Moser, Lanfranchi and then an unhappy Rodriguez in the misfiring B.R.M., last.
Next lap Hulme was up into second place, and on lap 20 he passed McLaren after getting round in 1 min. 25.3 sec. to take the lead narrowly from his “number one”, Spence and Amon, and these four were still driving in very close company. But Lanfranchi had retired with bad oil surge, and Siffert’s sixth place evaporated on lap 26 when the clutch broke in the Tasman-chassised Lotus, and two laps previously Gardner had gone out in a trail of smoke and steam when the B.R.M. engine broke a liner. Lap 28, and Spence slotted his slim B.R.M. past McLaren into second place, and as they lapped the tail-enders the leading group began to space out. But Amon closed on McLaren noticeably on lap 36 and was looking for a way by, but then lost time lapping Moser at Copse and dropped back, letting McLaren get away and latch on to Spence’s tail in second place. These two then drove very hard, entering corners side-by-side occasionally until lap 41 when the B.R.M.’s engine stopped suddenly at Club with a timing chain breakage, letting McLaren up into second place, but delaying him sufficiently to let Amon catch up in the Ferrari. Rodriguez had finally retired his sick B.R.M., Ickx was running a lonely fourth, with Courage fifth and about to be lapped, while the only other cars still running were Hobbs’ B.R.M. and Moser’s Brabham-Repco. Amon was trying hard to wrest second place from McLaren, setting a new outright circuit record on lap 44 of 1 min. 25.1 sec., 123.82 m.p.h., but Bruce was trying equally hard to stay ahead, doing 1 min. 25.2 sec. on the same lap, and, although the two of them were very close together on lap 45, Amon’s luck was running out and his goggles strap broke. Shielding his eyes from the airstream with one hand he drove for two laps before managing to haul his stand-by pair into position on his face, and this dropped him well back from McLaren, and although closing the gap slightly before the finish he came home in third place. Hulme was battered but triumphant, Bruce McLaren had a lot to smile about with his cars’ first one-two victory, and B.R.M. were well pleased with their turn of speed and not too worried about the frailty their cars had shown since they are still at an early stage in their development. The Ferraris had been rather outpaced from the start, but on a clear track and with McLaren as his target Amon had proved that he is one of the quickest drivers around.—D. C. N.

The supporting races were closely fought in the main, Jo Bonnier showing rare form in his Lola-Chevrolet T70 GT by holding-off Hulme in a similar car until about half-distance, then setting fastest race lap in a close dash to the finish. Tony Dean drove well to win the 2-litre class in his Porsche 906. The saloon car race, third round of the national Championship, was won by Muir in Shaw’s Falcon, winner of the previous two events, after Hobbs’ similar car had fallen out when offering stiff opposition. Elford won the 2-litre class for Porsche after Gardner’s Lotus-Cortina hit trouble, Rhodes’ Mini snatched the 1300 c.c. class from Fitzpatrick’s Escort at the finish as the Ford lost its final drive, and Craft dominated the 1-litre division in a Broadspeed Anglia. Finally, Miles won the F3 event narrowly from Pike’s Titan in an experimental Lotus 41X (née 55) and the Historic Car Race is reported more fully elsewhere in the issue.
